Specific leaf area

Specific leaf area is defined as the ratio of leaf area to dry mass.[1][2][3]

Application[edit]

Specific leaf area can be used to estimate the reproductive strategy of a particular plant based upon light and moisture (humidity) levels, among other factors.[4] Specific leaf area (SLA) is one of the most widely accepted key leaf characteristics used during the study of leaf traits.[5][6][7][8]

Measurement of leaf area[edit]

A device being used to non-destructively measure the area, length, width and perimeter of a leaf.

Portable leaf area meters can be used to provide a rapid, non-destructive measurement of leaf surface area, length, width and perimeter. Some can also measure diseased area by altering the sensitivity of the detecting system. These instruments have the ability to record the measured parameters as well as store a digital image of the leaf scanned.
