Lower leaves (older leaves) show symptoms first, since the plant will move nitrogen from older tissues to more important younger ones. [7] Nevertheless, plants are reported to show nitrogen deficiency symptoms at different parts. For example, Nitrogen deficiency of tea is identified by retarded shoot growth and yellowing of younger leaves. [8]
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. Leaf senescence has the important function of ...
An albino corn plant with no chlorophyll (left) beside a normal plant (right) In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll.As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white.
While these plants are relatively low maintenance, it’s not unusual for peace lily leaves to turn yellow here and there due to stress, pests, or other issues. This guide explains the most common ...

Chlorosis occurs in younger leaves because iron is not a mobile element, and as such, the younger leaves cannot draw iron from other areas of the plant. Over time, the yellowing may even turn a pale white or the whole leaf may be affected. [4] Iron deficient plants may overaccumulate heavy metals such as cadmium. [5]
It is found everywhere bananas are grown in Africa, Asia, Central and South America. It attacks banana plants of all ages and spreads mainly through the soil. It causes wilting and yellowing of the leaves. [7] F. oxysporum f. sp. lycopersici causes vascular wilt in tomato. The disease starts out as yellowing and drooping on one side of the plant.
Chimeric plants contain tissues with more than one genotype. [ further explanation needed ] A variegated chimera contains some tissues that produce chlorophyll and other tissues which do not. [ 7 ] Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation ...
