Merger into astrobotany[edit]

I propose that this page be merged in astrobotany. "Astrobotany" is the named sub-discipline and it was coined in the 1940s. It encompasses everything about plants in space. Tikhovcaptain (talk) 00:38, 12 May 2018 (UTC):[reply]

Astrobotany has meant "the branch of botany that investigates the possibility that plants grow on other planets "[1] Not only was that not what this article is about, its not what much of that article is about right now in a way it should not be. Fotaun (talk) 19:55, 12 May 2018 (UTC)[reply]

Plant Responses in Various Experiments[edit]

  • Allan H. Brown tested seedling movements aboard the Columbia space shuttle in 1983. Sunflower seedling movements were recorded while in orbit. They observed that the seedlings still experienced rotational growth and circumnation despite lack of gravity.
  • Several experiments are focused on how plant growth and distribution compares in space (without gravity) versus Earth conditions. One such experiment from the Canadian Space Agency, for example, found that white spruce seedlings grew differently in the anti-gravity space environment compared with Earth-bound seedlings;the space seedlings exhibited enhanced growth from the shoots and needles, along with and also had randomized amyloplast distribution compared with the Earth-bound control group.
  • Other experiments have found that plants have the ability exhibit gravitropism, even in low-gravity conditions. For instance, the ESA's European Modular Cultivation System enables experimentation with plant growth; acting as a miniature greenhouse, scientists aboard the international space station can investigate how plants react in variable-gravity conditions.The Gravi-1 experiment(2008)showed that plants sense the direction of gravity even at very low levels. A later experiment with the EMCS, Gravi-2, in 2014, displayed that plants change calcium signalling towards root growth while being grown in a several gravity levels.

Do you guy think these would make good edits? I think they are relevant and would make the page more informative, but I appreciate any and all constructive criticism/ideas/positive feedback.



Tomatosphere Research[edit]

Tomatosphere Research

Germination

Germination is the process of something coming into existence and developing. When tomato seeds germinate, they sprout. For tomato seeds to germinate best, they must be kept inside for six to eight weeks. They will typically sprout within five to ten days after being planted.

Tomato Seeds

Tomato seeds typically have a shelf life of four to five years, if kept in proper conditions. The seeds should be stored in a cool, dry place, preferably sixty degrees or under. The ISS has a wide variety of climates; on the side facing the sun, temperatures can soar up to a solid 250 degrees Fahrenheit, and on the dark side, temperatures may dive to -250 degrees Fahrenheit. If kept in improper conditions, the seeds will not germinate.

Tomatoes

There are over ten thousand varieties of tomatoes. The Heinz 9478 F1 Hybrid is mainly used for global processing by the Heinz company. Tomatoes originated in Peru, but were brought to Europe in the 1500’s. Tomatoes provide a variety of necessary nutrients. They are rich in lycopene, vitamin A, vitamin C, calcium, and potassium. They also acts as a built-in sunscreen if you eat them. Tomato plants come from the same family as the belladonna, or the deadly nightshade. Many things eat tomatoes and tomato plants. Aphids, tomato worms, slugs, spider mites, and stinkbugs damage tomatoes and tomato plants, along with many other organisms. Tomatoes are actually fruits. The confusion happened in the late 1800’s after the government named it a vegetable for taxation purposes. 

Radiation in Space

Most radiation in space is in the form of tiny particles from stars and other sources. Radiation to humans is referred to in two different terms. It can be acute, meaning a human is exposed to a high dose over a short period of time. It can also be chronic, meaning low levels are exposed over a longer period of time. Magnetic fields in Earth’s liquid iron core protect the planet from much of space’s radiation.

Radiation on the International Space Station

Workers on the ISS have instruments they use to measure radiation outside the station. ISS workers track each worker for signs of radiation. Radiation on the space station is very high, despite NASA’s attempt to shield it. Studies reveal that astronauts and workers are exposed to around 1 millisievert of radiation each day - that’s around how much the average person on earth is exposed to in a year.

Plants Grown in Space

The ISS has a large “space garden” where they grow sunflowers, lettuce, radishes, peas, carrots, rice, tulips, wheat, onions, parsley, and much more. A series NASA experiments, called Lada Validating Vegetable Production Unit, has revealed that food can be grown and safely consumed in space. Studies show that plants grow fine without gravity.

Orphaned references in Plants in space[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Plants in space's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Sputnik 2017":

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 19:02, 3 January 2019 (UTC)[reply]
