Edema (plants)
Edema, a condition in plants / From Wikipedia, the free encyclopedia
Edema, (also spelled oedema, and named from the analogous disorder in humans and other animals), is a disorder in plants caused by the build-up of water in plant tissues faster than the leaves can transpire.[1][2] The excess fluid bursts the cell membranes, causing the appearance of growths, particularly on the underside of leaves.[3]
