A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus Musa. In some countries, cooking bananas are called plantains, distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a peel, which may have a variety of colors when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless (parthenocarp) cultivated bananas come from two wild species – Musa acuminata and Musa balbisiana, or hybrids of them.

Musa species are native to tropical Indomalaya and Australia; they were probably domesticated in New Guinea. They are grown in 135 countries, primarily for their fruit, and to a lesser extent to make banana paper and textiles, while some are grown as ornamental plants. The world's largest producers of bananas in 2022 were India and China, which together accounted for approximately 26% of total production. Bananas are eaten raw or cooked in recipes varying from curries to banana chips, fritters, fruit preserves, or simply baked or steamed.

Worldwide, there is no sharp distinction between dessert "bananas" and cooking "plantains": this works well enough in the Americas and Europe, but it breaks down in Southeast Asia where many more kinds of bananas are grown and eaten. The term "banana" is applied also to other members of the genus Musa, such as the scarlet banana (Musa coccinea), the pink banana (Musa velutina), and the Fe'i bananas. Members of the genus Ensete, such as the snow banana (Ensete glaucum) and the economically important false banana (Ensete ventricosum) of Africa are sometimes included. Both genera are in the banana family, Musaceae.

Banana plantations are subject to damage by parasitic nematodes and insect pests, and to fungal and bacterial diseases, one of the most serious being Panama disease which is caused by a Fusarium fungus. This and black sigatoka threaten the production of Cavendish bananas, the main kind eaten in the Western world, which is a triploid Musa acuminata. Plant breeders are seeking new varieties, but these are difficult to breed given that commercial varieties are seedless. To enable future breeding, banana germplasm is conserved in multiple gene banks around the world.

Description

The banana plant is the largest herbaceous flowering plant. All the above-ground parts of a banana plant grow from a structure called a corm. Plants are normally tall and fairly sturdy with a treelike appearance, but what appears to be a trunk is actually a pseudostem composed of multiple leaf-stalks (petioles). Bananas grow in a wide variety of soils, as long as it is at least 60 centimetres (2.0 ft) deep, has good drainage and is not compacted. They are among the fastest growing of all plants, with daily surface growth rates recorded from 1.4 square metres (15 sq ft) to 1.6 square metres (17 sq ft).

The leaves of banana plants are composed of a stalk (petiole) and a blade (lamina). The base of the petiole widens to form a sheath; the tightly packed sheaths make up the pseudostem, which is all that supports the plant. The edges of the sheath meet when it is first produced, making it tubular. As new growth occurs in the centre of the pseudostem, the edges are forced apart. Cultivated banana plants vary in height depending on the variety and growing conditions. Most are around 5 m (16 ft) tall, with a range from 'Dwarf Cavendish' plants at around 3 m (10 ft) to 'Gros Michel' at 7 m (23 ft) or more. Leaves are spirally arranged and may grow 2.7 metres (8.9 ft) long and 60 cm (2.0 ft) wide. When a banana plant is mature, the corm stops producing new leaves and begins to form a flower spike or inflorescence. A stem develops which grows up inside the pseudostem, carrying the immature inflorescence until eventually it emerges at the top. Each pseudostem normally produces a single inflorescence, also known as the "banana heart". After fruiting, the pseudostem dies, but offshoots will normally have developed from the base, so that the plant as a whole is perennial. The inflorescence contains many petal-like bracts between rows of flowers. The female flowers (which can develop into fruit) appear in rows further up the stem (closer to the leaves) from the rows of male flowers. The ovary is inferior, meaning that the tiny petals and other flower parts appear at the tip of the ovary.

The banana fruits develop from the banana heart, in a large hanging cluster called a bunch, made up of around 9 tiers called hands, with up to 20 fruits to a hand. A bunch can weigh 22–65 kilograms (49–143 lb).

The fruit has been described as a "leathery berry". There is a protective outer layer (a peel or skin) with numerous long, thin strings (Vascular bundles), which run lengthwise between the skin and the edible inner portion. The inner part of the common yellow dessert variety can be split lengthwise into three sections that correspond to the inner portions of the three carpels by manually deforming the unopened fruit. In cultivated varieties, the seeds are diminished nearly to non-existence; their remnants are tiny black specks inside the fruit.

Taxonomy

Further information: List of banana cultivars

Musa 'Nendran' cultivar, grown widely in the Indian state of Kerala

The genus Musa was created by Carl Linnaeus in 1753. The name may be derived from Antonius Musa, physician to the Emperor Augustus, or Linnaeus may have adapted the Arabic word for banana, mauz. The ultimate origin of musa may be in the Trans–New Guinea languages, which have words similar to "#muku"; from there the name was borrowed into the Austronesian languages and across Asia, accompanying the cultivation of the banana as it was brought to new areas, via the Dravidian languages of India, into Arabic as a Wanderwort. The word "banana" is thought to be of West African origin, possibly from the Wolof word banaana, and passed into English via Spanish or Portuguese.

Musa is the type genus in the family Musaceae. The APG III system assigns Musaceae to the order Zingiberales, part of the commelinid clade of the monocotyledonous flowering plants. Some 70 species of Musa were recognized by the World Checklist of Selected Plant Families as of January 2013; several produce edible fruit, while others are cultivated as ornamentals.

The classification of cultivated bananas has long been a problematic issue for taxonomists. Linnaeus originally placed bananas into two species based only on their uses as food: Musa sapientum for dessert bananas and Musa paradisiaca for plantains. More species names were added, but this approach proved to be inadequate for the number of cultivars in the primary center of diversity of the genus, Southeast Asia. Many of these cultivars were given names that were later discovered to be synonyms.

In a series of papers published from 1947 onwards, Ernest Cheesman showed that Linnaeus's Musa sapientum and Musa paradisiaca were cultivars and descendants of two wild seed-producing species, Musa acuminata and Musa balbisiana, both first described by Luigi Aloysius Colla. Cheesman recommended the abolition of Linnaeus's species in favor of reclassifying bananas according to three morphologically distinct groups of cultivars – those primarily exhibiting the botanical characteristics of Musa balbisiana, those primarily exhibiting the botanical characteristics of Musa acuminata, and those with characteristics of both. Researchers Norman Simmonds and Ken Shepherd proposed a genome-based nomenclature system in 1955. This system eliminated almost all the difficulties and inconsistencies of the earlier classification of bananas based on assigning scientific names to cultivated varieties. Despite this, the original names are still recognized by some authorities, leading to confusion.

The accepted scientific names for most groups of cultivated bananas are Musa acuminata Colla and Musa balbisiana Colla for the ancestral species, and Musa × paradisiaca L. for the hybrid of the two.

Informal classification

In regions such as North America and Europe, Musa fruits offered for sale can be divided into small sweet "bananas" eaten raw when ripe as a dessert, and large starchy "plantains" or cooking bananas, which do not have to be ripe. Linnaeus made this distinction when naming two "species" of Musa. Members of the "plantain subgroup" of banana cultivars, most important as food in West Africa and Latin America, correspond to this description, having long pointed fruit. They are described by Ploetz et al. as "true" plantains, distinct from other cooking bananas.

The cooking bananas of East Africa however belong to a different group, the East African Highland bananas. Further, small farmers in Colombia grow a much wider range of cultivars than large commercial plantations do, and in Southeast Asia—the center of diversity for bananas, both wild and cultivated—the distinction between "bananas" and "plantains" does not work. Many bananas are used both raw and cooked. There are starchy cooking bananas which are smaller than those eaten raw. The range of colors, sizes and shapes is far wider than in those grown or sold in Africa, Europe or the Americas. Southeast Asian languages do not make the distinction between "bananas" and "plantains" that is made in English. Thus both Cavendish dessert bananas and Saba cooking bananas are called pisang in Malaysia and Indonesia, kluai in Thailand and chuối in Vietnam. Fe'i bananas, grown and eaten in the islands of the Pacific, are derived from a different wild species. Most Fe'i bananas are cooked, but Karat bananas, which are short and squat with bright red skins, are eaten raw.

History

Domestication

See also: Musa acuminata, Domesticated plants and animals of Austronesia, and East African Highland bananas

The earliest domestication of bananas (Musa spp.) was from naturally occurring parthenocarpic (seedless) individuals of Musa banksii in New Guinea. These were cultivated by Papuans before the arrival of Austronesian-speakers. Numerous phytoliths of bananas have been recovered from the Kuk Swamp archaeological site and dated to around 10,000 to 6,500 BP. Foraging humans in this area began domestication in the late Pleistocene using transplantation and early cultivation methods. By the early to middle of the Holocene the process was complete. From New Guinea, cultivated bananas spread westward into Island Southeast Asia through proximity (not migrations). They hybridized with other (possibly independently domesticated) subspecies of Musa acuminata as well as M. balbisiana in the Philippines, northern New Guinea, and possibly Halmahera. These hybridization events produced the triploid cultivars of bananas commonly grown today.

Spread

From Island Southeast Asia, bananas became part of the staple domesticated crops of Austronesian peoples and were spread during their voyages and ancient maritime trading routes into Oceania, East Africa, South Asia, and Indochina.

These ancient introductions resulted in the banana subgroup now known as the true plantains, which include the East African Highland bananas and the Pacific plantains (the Iholena and Maoli-Popo'ulu subgroups). East African Highland bananas originated from banana populations introduced to Madagascar probably from the region between Java, Borneo, and New Guinea; while Pacific plantains were introduced to the Pacific Islands from either eastern New Guinea or the Bismarck Archipelago.

Phytolith discoveries in Cameroon dating to the first millennium BCE triggered an as yet unresolved debate about the date of first cultivation in Africa. There is linguistic evidence that bananas were known in East Africa or Madagascar around that time. The earliest prior evidence indicates that cultivation dates to no earlier than the late 6th century CE. It is likely, however, that bananas were brought at least to Madagascar if not to the East African coast during the phase of Malagasy colonization of the island from South East Asia c. 400 CE. Glucanase and two other proteins specific to bananas were found in dental calculus from the early Iron Age (12th century BCE) Philistines in Tel Erani in the southern Levant.

Another wave of introductions later spread bananas to other parts of tropical Asia, particularly Indochina and the Indian subcontinent. However, there is evidence that bananas were known to the Indus Valley civilisation from phytoliths recovered from the Kot Diji archaeological site in Pakistan. This may indicate very early dispersal of bananas by Austronesian traders by sea from as early as 2000 BCE, or they may have come from local wild Musa species used for fiber or as ornamentals, not food. Southeast Asia remains the region of primary diversity of the banana. Areas of secondary diversity are found in Africa, indicating a long history of banana cultivation there.

Arab Agricultural Revolution

The banana may have been present in isolated locations elsewhere in the Middle East on the eve of Islam. The spread of Islam was followed by far-reaching diffusion. There are numerous references to it in Islamic texts (such as poems and hadiths) beginning in the 9th century. By the 10th century the banana appears in texts from Palestine and Egypt. From there it diffused into North Africa and Muslim Iberia during the Arab Agricultural Revolution. An article on banana tree cultivation is included in Ibn al-'Awwam's 12th-century agricultural work, Kitāb al-Filāḥa (Book on Agriculture). During the Middle Ages, bananas from Granada were considered among the best in the Arab world. Bananas were certainly grown in the Christian Kingdom of Cyprus by the late medieval period. Writing in 1458, the Italian traveller and writer Gabriele Capodilista wrote favourably of the extensive farm produce of the estates at Episkopi, near modern-day Limassol, including the region's banana plantations.

Bananas were encountered by European explorers during the Magellan expedition in 1521, in both Guam and the Philippines. Lacking a name for the fruit, the ship's historian Antonio Pigafetta described them as "figs more than one palm long." Bananas were introduced to South America by Portuguese sailors who brought them from West Africa in the 16th century. Southeast Asian banana cultivars, as well as abaca grown for fibers, were introduced to North and Central America by the Spanish from the Philippines, via the Manila galleons. Many wild banana species and cultivars exist in India, China, and Southeast Asia.

Plantation cultivation

Further information: History of modern banana plantations in the Americas

Plantation in the Philippines, 2010

In the 15th and 16th centuries, Portuguese colonists started banana plantations in the Atlantic Islands, Brazil, and western Africa. North Americans began consuming bananas on a small scale at very high prices shortly after the Civil War, though it was only in the 1880s that the food became more widespread. As late as the Victorian Era, bananas were not widely known in Europe, although they were available. The earliest modern plantations originated in Jamaica and the related Western Caribbean Zone, including most of Central America. It involved the combination of modern transportation networks of steamships and railroads with the development of refrigeration that allowed more time between harvesting and ripening. North American shippers like Lorenzo Dow Baker and Andrew Preston, the founders of the Boston Fruit Company started this process in the 1870s, but railroad builders like Minor C. Keith participated, culminating in the multi-national giant corporations like Chiquita and Dole. These companies were monopolistic, vertically integrated (controlling growing, processing, shipping and marketing) and usually used political manipulation to build enclave economies (internally self-sufficient, virtually tax exempt, and export-oriented, contributing little to the host economy). Their political maneuvers, which gave rise to the term banana republic for states such as Honduras and Guatemala, included working with local elites and their rivalries to influence politics or playing the international interests of the United States, especially during the Cold War, to keep the political climate favorable to their interests. In the modern United States, Hawaii is by far the largest banana producer, followed by Florida.

Peasant cultivation

Small-scale banana production, Liberia, 2013

The vast majority of the world's bananas are cultivated for family consumption or for sale on local markets. India is the world leader in this sort of production, but many other Asian and African countries where climate and soil conditions allow cultivation also host large populations of banana growers who sell at least some of their crop. Peasants with smallholdings of 1 to 2 acres in the Caribbean produce bananas for the world market, often alongside other crops.

Modern cultivation

See also: List of banana cultivars

Bananas are propagated asexually from offshoots. The plant is allowed to produce two shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. As a non-seasonal crop, bananas are available fresh year-round. They are grown in some 135 countries.

Cavendish

Main article: Cavendish banana

Cultivars in the Cavendish group dominate the world market.

In global commerce in 2009, by far the most important cultivars belonged to the triploid Musa acuminata AAA group of Cavendish group bananas. It is unclear if any existing cultivar can replace Cavendish bananas, so various hybridisation and genetic engineering programs are attempting to create a disease-resistant, mass-market banana. One such strain that has emerged is the Taiwanese Cavendish or Formosana.

Ripening

Ralstonia solanacearum on an overripe banana

Export bananas are picked green, and ripened in special rooms upon arrival in the destination country. These rooms are air-tight and filled with ethylene gas to induce ripening. This mimics the normal production of this gas as a ripening hormone. Ethylene stimulates the formation of amylase, an enzyme that breaks down starch into sugar, influencing the taste. Ethylene signals the production of pectinase, an enzyme which breaks down the pectin between the cells of the banana, causing the banana to soften as it ripens. The vivid yellow color consumers normally associate with supermarket bananas is caused by ripening around 18 °C (64 °F), and does not occur in Cavendish bananas ripened in tropical temperatures (over 27 °C (81 °F)).

Storage and transport

Bananas are transported over long distances from the tropics to world markets. To obtain maximum shelf life, harvest comes before the fruit is mature. The fruit requires careful handling, rapid transport to ports, cooling, and refrigerated shipping. The goal is to prevent the bananas from producing their natural ripening agent, ethylene. This technology allows storage and transport for 3–4 weeks at 13 °C (55 °F). On arrival, bananas are held at about 17 °C (63 °F) and treated with a low concentration of ethylene. After a few days, the fruit begins to ripen and is distributed for final sale. Ripe bananas can be held for a few days at home. If bananas are too green, they can be put in a brown paper bag with an apple or tomato overnight to speed up the ripening process.

Sustainability

The excessive use of fertilizers contributes greatly to eutrophication in streams and lakes, and harms aquatic life after algal blooms deprive fish of oxygen. It has been theorized that destruction of 60% of coral reefs along the coasts of Costa Rica is partially from sediments from banana plantations. Another issue is the deforestation associated with expanding banana production. As monocultures rapidly deplete soil nutrients plantations expand to areas with rich soils and cut down forests, which also affects soil erosion and degradation, and increases frequency of flooding. The World Wildlife Fund stated that banana production produced more waste than any other agricultural sector, with discarded banana plants, bags used to cover the bananas, strings to tie them, and containers for transport.

Voluntary sustainability standards such as Rainforest Alliance and Fairtrade are being used to address some of these issues. Bananas production certified in this way grew rapidly at the start of the 21st century to represent 36% of banana exports by 2016.

Breeding

Mutation breeding can be used in this crop. Aneuploidy is a source of significant variation in allotriploid varieties. For one example, it can be a source of TR4 resistance. Lab protocols have been devised to screen for such aberrations and for possible resulting disease resistances. Wild Musa spp. provide useful resistance genetics, and are vital to breeding for TR4 resistance, as shown in introgressed resistance from wild relatives.

The Honduran Foundation for Agricultural Research attempted to exploit the rare cases of seed production to create disease-resistant varieties by conventional breeding; 30,000 commercial banana plants were hand-pollinated with pollen from wild fertile Asian fruit, producing 400 tonnes, which contained about fifteen seeds, of which four or five germinated. Further breeding with wild bananas yielded a new seedless variety resistant to both black Sigatoka and Panama disease.

Source: FAOSTAT of the United Nations Note: Some countries distinguish between bananas and plantains, but four of the top six producers do not, thus necessitating comparisons using the total for bananas and plantains combined.

Bananas are exported in larger volume and to a larger value than any other fruit. In 2022, world production of bananas and plantains combined was 179 million tonnes, led by India and China with a combined total of 26% of global production. Other major producers were Uganda, Indonesia, the Philippines, Nigeria and Ecuador. As reported for 2013, total world exports were 20 million tonnes of bananas and 859,000 tonnes of plantains. Ecuador and the Philippines were the leading exporters with 5.4 and 3.3 million tonnes, respectively, and the Dominican Republic was the leading exporter of plantains with 210,350 tonnes.

Developing countries

Bananas and plantains are a major staple food crop for millions of people in developing countries. In many tropical countries, the main cultivars produce green (unripe) bananas used for cooking. Most producers are small-scale farmers either for home consumption or local markets. Because bananas and plantains produce fruit year-round, they provide a valuable food source during the hunger season between harvests of other crops. Bananas and plantains are thus important for global food security.

Pests

Nematodes

Banana roots are subject to damage from multiple species of parasitic nematodes. Radopholus similis causes nematode root rot, the most serious nematode disease of bananas in economic terms. Root-knot is the result of infection by species of Meloidogyne, while root-lesion is caused by species of Pratylenchus, and spiral nematode root damage is the result of infection by Helicotylenchus species.

Insects

Among the main insect pests of banana cultivation are two beetles that cause substantial economic losses, the banana borer Cosmopolites sordidus and the banana stem weevil Odoiporus longicollis. Other significant pests include aphids and scarring beetles.

The banana borer is a destructive pest that tunnels inside the plant.

Diseases

Main article: List of banana and plantain diseases

Although in no danger of outright extinction, bananas of the Cavendish group, which dominate the global market, are under threat. Its predecessor 'Gros Michel', discovered in the 1820s, was similarly dominant but had to be replaced after widespread infections of Panama Disease. Monocropping of Cavendish similarly leaves it susceptible to disease and so threatens both commercial cultivation and small-scale subsistence farming. Within the data gathered from the genes of hundreds of bananas, the botanist Julie Sardos has found several wild banana ancestors currently unknown to scientists, whose genes could provide a means of defense against banana crop diseases.

Some commentators have remarked that those variants which could replace what much of the world considers a "typical banana" are so different that most people would not consider them the same fruit, and blame the decline of the banana on monogenetic cultivation driven by short-term commercial motives. Overall, fungal diseases are disproportionately important to small island developing states.

Panama disease

Panama disease Fusarium fungus climbing up through the banana stem

Panama disease is caused by a Fusarium soil fungus, which enters the plants through the roots and travels with water into the trunk and leaves, producing gels and gums that cut off the flow of water and nutrients, causing the plant to wilt, and exposing the rest of the plant to lethal amounts of sunlight. Prior to 1960, almost all commercial banana production centered on the Gros Michel cultivar, which was highly susceptible. Cavendish was chosen as the replacement for Gros Michel because, among resistant cultivars, it produces the highest quality fruit. However, more care is required for shipping the Cavendish, and its quality compared to Gros Michel is debated.

Fusarium wilt TR4

Fusarium wilt TR4, a reinvigorated strain of Panama disease, was discovered in 1993. This virulent form of Fusarium wilt has destroyed Cavendish plantations in several southeast Asian countries and spread to Australia and India. As the soil-based fungi can easily be carried on boots, clothing, or tools, the wilt spread to the Americas despite years of preventive efforts. Without genetic diversity, Cavendish is highly susceptible to TR4, and the disease endangers its commercial production worldwide. The only known defense to TR4 is genetic resistance. This is conferred either by RGA2, a gene isolated from a TR4-resistant diploid banana, or by the nematode-derived Ced9. This may be achieved by genetic modification. Experts state the need to enrich banana biodiversity by producing diverse new banana varieties, not just having a focus on the Cavendish.

Black sigatoka

Leaf infected with black sigatoka

Black sigatoka is a fungal leaf spot disease first observed in Fiji in 1963 or 1964. It is caused by the ascomycete Mycosphaerella fijiensis. The disease, also called black leaf streak, has spread to banana plantations throughout the tropics from infected banana leaves used as packing material. It affects all main cultivars of bananas and plantains (including the Cavendish cultivars), impeding photosynthesis by blackening parts of the leaves, eventually killing the entire leaf. Starved for energy, fruit production falls by 50% or more, and the bananas that do grow ripen prematurely, making them unsuitable for export. The fungus has shown ever-increasing resistance to treatment, with the current expense for treating 1 hectare (2.5 acres) exceeding US$1,000 per year; spraying with fungicides may be required as often as 50 times a year. In addition to the expense, there is the question of how long intensive spraying can be environmentally justified.

Banana bunchy top virus

Colony of banana aphids (Pentalonia nigronervosa), vector of banana bunchy top virus

Banana bunchy top virus (BBTV) is a plant virus of the genus Babuvirus, family Nanonviridae affecting Musa spp. (including banana, abaca, plantain and ornamental bananas) and Ensete spp. in the family Musaceae. Banana bunchy top disease (BBTD) symptoms include dark green streaks of variable length in leaf veins, midribs and petioles. Leaves become short and stunted as the disease progresses, becoming 'bunched' at the apex of the plant. Infected plants may produce no fruit or the fruit bunch may not emerge from the pseudostem. The virus is transmitted by the banana aphid Pentalonia nigronervosa and is widespread in Southeast Asia, Asia, the Philippines, Taiwan, Oceania and parts of Africa. There is no cure for BBTD, but it can be effectively controlled by the eradication of diseased plants and the use of virus-free planting material. No resistant cultivars have been found, but varietal differences in susceptibility have been reported. The commercially important Cavendish subgroup is severely affected.

Banana bacterial wilt

Banana bacterial wilt (BBW) is a bacterial disease caused by Xanthomonas campestris pv. musacearum. First identified on a close relative of bananas, Ensete ventricosum, in Ethiopia in the 1960s, BBW occurred in Uganda in 2001 affecting all banana cultivars. Since then BBW has been diagnosed in Central and East Africa including the banana growing regions of Rwanda, the Democratic Republic of the Congo, Tanzania, Kenya, Burundi, and Uganda.

Conservation of genetic diversity

The cold storage room for the banana collection at Bioversity International's Musa Germplasm Transit Centre

Given the narrow range of genetic diversity present in bananas and the many threats via biotic (pests and diseases) and abiotic threats (such as drought) stress, conservation of the full spectrum of banana genetic resources is ongoing. In 2024, the economist Pascal Liu of the FAO described the impact of global warming as an "enormous threat" to the world supply of bananas.

Banana germplasm is conserved in many national and regional gene banks, and at the world's largest banana collection, the International Musa Germplasm Transit Centre, managed by Bioversity International and hosted at KU Leuven in Belgium. Musa cultivars are usually seedless, and options for their long-term conservation are constrained by the vegetative nature of the plant's reproductive system. Consequently, they are conserved by three main methods: in vivo (planted in field collections), in vitro (as plantlets in test tubes within a controlled environment), and by cryopreservation (meristems conserved in liquid nitrogen at −196 °C).

Genes from wild banana species are conserved as DNA and as cryopreserved pollen and banana seeds from wild species are also conserved, although less commonly, as they are difficult to regenerate. In addition, bananas and their crop wild relatives are conserved in situ (in wild natural habitats where they evolved and continue to do so). Diversity is also conserved in farmers' fields where continuous cultivation, adaptation and improvement of cultivars is often carried out by small-scale farmers growing traditional local cultivars.

Bananas are a staple starch for many tropical populations. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Both the skin and inner part can be eaten raw or cooked. The primary component of the aroma of fresh bananas is isoamyl acetate (also known as banana oil), which, along with several other compounds such as butyl acetate and isobutyl acetate, is a significant contributor to banana flavor.

Plantains are eaten cooked, such as made into fritters. Pisang goreng, bananas fried with batter is a popular street food in Southeast Asia. Bananas feature in Philippine cuisine, with desserts like maruya banana fritters. Bananas can be made into fruit preserves. Banana chips are a snack produced from sliced and fried bananas, such as in Kerala. Dried bananas are ground to make banana flour.

Flowers

Banana flowers (also called "banana hearts" or "banana blossoms") are used as a vegetable in South Asian and Southeast Asian cuisine. The flavor resembles that of artichoke. As with artichokes, both the fleshy part of the bracts and the heart are edible.

Leaf

Main article: Banana leaf

Banana leaves are large, flexible, and waterproof. While generally too tough to actually be eaten, they are often used as ecologically friendly disposable food containers or as "plates" in South Asia and several Southeast Asian countries. In Indonesian cuisine, banana leaf is employed in cooking methods like pepes and botok; banana leaf packages containing food ingredients and spices are cooked in steam or in boiled water, or are grilled on charcoal. Certain types of tamales are wrapped in banana leaves instead of corn husks.

When used so for steaming or grilling, the banana leaves protect the food ingredients from burning and add a subtle sweet flavor. In South India, it is customary to serve traditional food on a banana leaf. In Tamil Nadu (India), dried banana leaves are used as to pack food and to make cups to hold liquid food items.

Paper and textiles

Further information: Manila hemp and Banana paper

Banana fiber harvested from the pseudostems and leaves has been used for textiles in Asia since at least the 13th century. Both fruit-bearing and fibrous banana species have been used. In the Japanese system Kijōka-bashōfu, leaves and shoots are cut from the plant periodically to ensure softness. Harvested shoots are first boiled in lye to prepare fibers for yarn-making. These banana shoots produce fibers of varying degrees of softness, yielding yarns and textiles with differing qualities for specific uses. For example, the outermost fibers of the shoots are the coarsest, and are suitable for tablecloths, while the softest innermost fibers are desirable for kimono and kamishimo. This traditional Japanese cloth-making process requires many steps, all performed by hand. Banana paper can be made either from the bark of the banana plant, mainly for artistic purposes, or from the fibers of the stem and non-usable fruits. The paper may be hand-made or industrially processed.

Other uses

The large leaves of bananas may also be used as umbrellas.

Banana peel may have capability to extract heavy metal contamination from river water, similar to other purification materials. Waste bananas can be used to feed livestock.

As with all living things, potassium-containing bananas emit radioactivity at low levels occurring naturally from the potassium-40 (K-40) isotope. The banana equivalent dose of radiation was developed in 1995 as a simple teaching-tool to educate the public about the natural, small amount of K-40 radiation occurring in everyone and in common foods.

Cultural roles

Arts

The Edo period poet Matsuo Bashō is named after the Japanese word 芭蕉 (Bashō) for the Japanese banana. The Bashō planted in his garden by a grateful student became a source of inspiration to his poetry, as well as a symbol of his life and home.

The song "Yes! We Have No Bananas" was written by Frank Silver and Irving Cohn and originally released in 1923; for many decades, it was the best-selling sheet music in history. Since then the song has been rerecorded several times and has been particularly popular during banana shortages.

A person slipping on a banana peel has been a staple of physical comedy for generations. An American comedy recording from 1910 features a popular character of the time, "Uncle Josh", claiming to describe his own such incident.

The cover artwork for the debut album of The Velvet Underground features a banana made by Andy Warhol. On the original vinyl LP version, the design allowed the listener to "peel" this banana to find a pink, peeled phallic banana on the inside.

Italian artist Maurizio Cattelan created a concept art piece titled Comedian involving taping a banana to a wall using silver duct tape. The piece was exhibited briefly at the Art Basel in Miami before being removed from the exhibition and eaten without permission in another artistic stunt titled Hungry Artist by New York artist David Datuna.

Religion and folklore

Nang Tani, the female ghost of Thai folklore that haunts banana plants

In India, bananas serve a prominent part in many festivals and occasions of Hindus. In South Indian weddings, particularly Tamil weddings, banana trees are tied in pairs to form an arch as a blessing to the couple for a long-lasting, useful life.

In Thailand, it is believed that a certain type of banana plant may be inhabited by a spirit, Nang Tani, a type of ghost related to trees and similar plants that manifests itself as a young woman. Often people tie a length of colored satin cloth around the pseudostem of the banana plants.

In Malay folklore, the ghost known as Pontianak is associated with banana plants (pokok pisang), and its spirit is said to reside in them during the day.

The Bridgeport, Connecticut, Centennial half dollar (also the Bridgeport Centennial half dollar or Bridgeport half dollar) is a commemorative fifty-cent piece issued in 1936 by the United States Bureau of the Mint to honor the 100th anniversary of the incorporation of Bridgeport, Connecticut as a city. Designed by Henry Kreis, the obverse depicts the showman P. T. Barnum, who was one of Bridgeport's most famous residents, was mayor of the city, helped develop it, and is buried there. The reverse depicts a stylized eagle.

Bridgeport authorities wanted a commemorative coin to help fund the centennial celebrations. At the time, Congress was authorizing such coins for even local events, and the Bridgeport half dollar legislation passed Congress without opposition. Kreis had designed the Connecticut Tercentenary half dollar (1935), and he produced designs showing a left-facing Barnum and a modernistic eagle similar to the one on the Connecticut piece.

The coins were vended to the public beginning in September 1936 at a price of $2. Too late for most of the centennial celebrations, the coins nevertheless sold well, though leaving an unsold remainder of several thousand pieces. These were bought up by coin dealers and wholesale quantities were available on the secondary market until the 1970s. The Bridgeport half dollar sells in the low hundreds of dollars, depending on condition.

Background

Bridgeport, the largest city in Connecticut, was named after a drawbridge that local residents were proud of. Settled in 1647, it was an important center during the 17th and 18th centuries, but was not incorporated as a city until 1836. Elias Howe, inventor of the modern sewing machine, built a factory there.

Among Bridgeport's famous residents was P.T. Barnum, the showman, who became mayor of the city, served in the Connecticut Legislature, and is buried there. He endowed the (now defunct) Barnum Museum of Natural History at Tufts University in Massachusetts, but as numismatic writer Arlie Slabaugh Jr. put it, "his greatest monument is the circus. Don't you see that sawdust ring, hear the calliope?" The Ringling Bros. and Barnum & Bailey Circus survived until 2017.

Until 1954, the entire mintage of each commemorative coin issues issue was sold by the government at face value to a group named by Congress in authorizing legislation, who then tried to sell the coins at a profit to the public. The new pieces then entered the secondary market, and in early 1936 all earlier commemoratives sold at a premium to their issue prices. The apparent easy profits to be made by purchasing and holding commemoratives attracted many to the coin collecting hobby, where they sought to purchase the new issues. The growing market for such pieces led to many commemorative coin proposals in Congress, to mark anniversaries and benefit (it was hoped) worthy causes, including some of purely local significance. Among these were the Bridgeport piece, intended to fund local celebrations of the city's centennial; the designated group was Bridgeport Centennial, Inc., in charge of the celebrations.

Legislation

P.T. Barnum

A bill for a Bridgeport Centennial half dollar was introduced into the United States Senate by Augustine Lonergan of Connecticut on March 10, 1936. The other Connecticut senator, Francis T. Maloney, had been asked three or four weeks previously to introduce the bill, but Senator Maloney had chosen not to do so because of the many commemorative coin bills already before the Senate. The Bridgeport bill was referred to the Committee on Banking and Currency, and was one of several commemorative coin bills to be considered on March 11, 1936, by a subcommittee led by Colorado's Alva B. Adams.

Senator Adams had heard of the commemorative coin abuses of the mid-1930s, with issuers increasing the number of coins needed for a complete set by having them issued at different mints with different mint marks; authorizing legislation placed no prohibition on this. Lyman W. Hoffecker, a Texas coin dealer and official of the American Numismatic Association, testified and told the subcommittee that some issues, like the Oregon Trail Memorial half dollar, first struck in 1926, had been issued over the course of years with different dates and mint marks. Other issues had been entirely bought up by single dealers, and some low-mintage varieties of commemorative coins were selling at high prices. The many varieties and inflated prices for some issues that resulted from these practices angered coin collectors trying to keep their collections current.

On March 26, Adams reported the bill back to the Senate, though with extensive amendments. The coins could only be struck at one mint; there would be a mintage limit of 10,000 coins and no fewer than 5,000 could be made at a time. They would have to be dated 1936, and Bridgeport Centennial, Inc., the organization designated to purchase the coins, had one year to do so. The net proceeds Bridgeport Centennial, Inc. received from selling the coins could only be used for the centennial observances. The bill was brought to the Senate floor on March 27, 1936, the second of six coinage bills being considered one after the other. Like the others, it was amended and passed without recorded discussion or dissent.

The bill reached the House of Representatives on April 1 and was referred to the Committee on Coinage, Weights, and Measures. That committee reported back on the 16th, recommending an amendment to require that not less than 25,000 coins be struck. The amendment deleted the language requiring 5,000 to be minted at a time, as well as the one-year time limit. On April 28, Schuyler Merritt of Connecticut brought the bill to the House floor, asking that it be passed with the recommended amendment, and it was, without any discussion or dissent.

As the two houses had not passed identical versions, this sent the bill back to the Senate. On May 4, Adams moved that the Senate agree to the House amendment, which it did; the bill became law, authorizing not fewer than 25,000 half dollars, with the signature of President Franklin D. Roosevelt on May 15, 1936. The lack of an upper mintage limit or a time limit for production meant that Bridgeport Centennial, Inc. could have ordered as many coins as it wanted as far into the future as it cared to as long as they were dated 1936. Any such authority was removed by Congress with legislation passed August 5, 1939, directing that commemorative coins authorized before March 1 of that year be no longer struck.

Preparation

P. T. Barnum, sculpted by Thomas Ball (1887), Seaside Park, Bridgeport, Connecticut

On June 10, 1936, Bridgeport mayor Jasper McLevy wrote to Director of the United States Mint Nellie Tayloe Ross, informing her that Henry Kreis, designer of the Connecticut Tercentenary half dollar, had been hired to sculpt the Bridgeport coin, and enclosing sketches of the proposed design. McLevy noted that Barnum was the subject of one side of the coin, and explained that Barnum had presented Seaside Park to the city and had helped develop East Bridgeport. The following day, Ross wrote to Secretary of the Treasury Henry Morgenthau Jr. stating that the Bridgeport designs would be forwarded to the Commission of Fine Arts for its opinion before Morgenthau was called upon to give final approval. The commission was charged by a 1921 executive order by President Warren G. Harding with rendering advisory opinions on public artworks, including coins. She noted that while the question of whether Barnum should appear on the coin was not in the jurisdiction of the commission, that had not stopped it from weighing in against the appearance of Stephen Foster on the Cincinnati Musical Center half dollar.

On June 24, 1936, the commission chair, Charles Moore, wrote to Ross, enclosing comments from Lee Lawrie, sculptor-member of the commission, generally approving of Kreis's designs, but proposing that the words LIBERTY and IN GOD WE TRUST be moved from below Barnum's head on the obverse to the reverse. This, Lawrie suggested, would allow space for the name CONNECTICUT (abbreviated as CONN. on the original) to be rendered in full. Revised models were approved by the commission, and on August 4, the completed models for the coins were sent to Morgenthau by Assistant Director of the Mint Mary M. O'Reilly. The models were converted to coin-sized hubs by the Medallic Art Company of New York in time for coinage to begin in September.

Design

The obverse of the Bridgeport half dollar depicts the bust of P.T. Barnum, a subject that has absorbed much of the commentary on the coin's design. Michael K. Garofalo, in his article on Kreis, stated, "although the portrait bears a very strong likeness to Barnum, the rendering was merely average for the talented Kreis." Anthony Swiatek and Walter Breen, in their volume on commemoratives, aver that "the choice of P.T. Barnum, of all imaginable people ... has less to do with his 'There's a sucker born every minute' cynicism (however applicable this might have been to commemorative coin fanciers in the 1930s) than to his philanthropic benefactions to the city." Breen called Barnum the patron saint of coin collectors. Dealer B. Max Mehl, in his 1937 work on commemoratives, suggested purchasers of the coin were "suckers", and wrote, "we think that Barnum's likeness, in view of his famous remark, is certainly most appropriate".

Mehl also criticized the reverse of the coin:

The eagle (?) on the new Bridgeport half dollar is the biggest joke as a specimen of our noble bird that ever appeared on a coin.[cite references] Not a feather appears on its tin-roof surface, and several beholders said it resembled an airplane. Turn it around and you have a fine shark with two dorsal fins, an open mouth and a tongue. The shark appears to be laughing. I wonder at whom? And how apropos that P.T. Barnum's portrait adorns the other side. He was right in his famous remarks years ago.

Kreis's eagle for the Connecticut Tercentenary half dollar

Q. David Bowers describes Kreis's eagle as modernistic and noted its resemblance to the one the sculptor had created for the Connecticut half dollar. Don Taxay, writing in 1966, concurred, considering the eagle the most modernistic seen on any coin. Coin writer Kevin Flynn called it an "ultra modern eagle". Garofalo stated, "Kreis' highly stylized eagle met with mixed reviews. Critically acclaimed by the art world, it bewildered the public, many of whom did not readily identify the bird as the nation's symbol." Kreis's initial K is found incuse in the lower right.

Swiatek and Breen deemed the coin a "very Art Deco composition". According to Garofalo, "From an artistic standpoint, Kreis' designs for the Bridgeport half dollar were an amazing success. The obverse was conservative and accurate, as a portrait should be, and the reverse was stylish and inspirational." Art historian Cornelius Vermeule, in his volume on U.S. coins and medals, stated that the Bridgeport piece "has been cited as one of the more successful commemorative coins within the broad tradition instituted by Augustus Saint-Gaudens". He described the piece as having "P.T. Barnum in large, thoughtful profile and a thrusting eagle of conceptual, metallic style", and praised the lettering, finding the placement of the patriotic mottos on the reverse done "not inartistically". Vermeule suggested that Kreis was unable to find a suitable Bridgeport-related theme for the reverse, and instead turned "to a new interpretation of elements, such as the eagle, used in the coins of the regular issue. A coin honoring P.T. Barnum could have featured a lion, an elephant, or a performing bear on the reverse, but this product of the civic enterprise of Bridgeport gains great merit for showing an exciting new form of the national bird".

Production, distribution and collecting

In September 1936, a total of 25,015 Bridgeport half dollars were struck at the Philadelphia Mint with 15 pieces reserved for inspection and testing the following year by the annual Assay Commission. They were sold at a price of $2, mostly through local banks in Bridgeport. Mail order sales were processed by the First National Bank of Bridgeport. By this time, many of the centennial celebrations had passed, having begun June 4, though they continued until October 3. Individual coins were sold in small cardboard boxes, with a limit of five per purchaser. Despite its relatively high price and the fact that it was released after many of the centennial celebrations, the coin sold well with both the public and collectors.

Several thousand pieces remained unsold, and transferred by the centennial organizers to the Bridgeport Community Chest, which sold them wholesale to coin dealers at a slight advance on face value. In the 1950s, Toivo Johnson, a coin dealer in Maine, possessed about a thousand of them, and rolls of 20 were sold at coin conventions for years after; many were acquired and then sold by a coin investment firm in the early 1970s.

By 1940 the Bridgeport piece sold for about $1.50 in uncirculated condition, though this went up to $2.50 by 1950, $12 by 1960, and $250 by 1985. The deluxe edition of R. S. Yeoman's A Guide Book of United States Coins, published in 2018, lists the coin for between $120 and $300, depending on condition. An exceptional specimen sold for $1,880 in 2015.
