Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. [ 1 ] Chlorophyll degradation during leaf senescence reveals the carotenoids , such as anthocyanin and xanthophylls, which are the cause of autumn leaf color in deciduous trees.
Severe cases can cause stunted growth, a spindly appearance, [4] and yellow leaves which can eventually fall off of the plant. [ 5 ] The disorder is not infectious and if edema is the only problem, then the plants are safe to handle and the parts of the plant which would usually be edible will remain safe to eat. [ 8 ]
