eruptions. Susceptibility to edema varies by plant species but almost any broad-leaved plant can be affected. In severely affected plants the growths can also appear on the stems and cause leaves to turn yellow and drop off, leaves can also become distorted. If the conditions causing edema are prolonged then the plant can become spindly and have stunted growth.
106:
Edema causes the appearance of growths, mainly on the underside of leaves, and can also cause indentations on the top side of leaves. The growths can take a different appearance depending on the plant species, but can often take the form of needle like hairs, blisters, corky growths and white crusty

Severe cases can cause stunted growth, a spindly appearance, and yellow leaves which can eventually fall off of the plant.

A number of changes to the growing environment can all contribute to the improvement of edema symptoms. These include:
