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.
Symptoms of nitrogen deficiencies in plants is general chlorosis of the leaves, which is when leaves turn pale green, and leaves cup upwards quite severely in deficient plants. [4] Nitrogen deficiencies also cause leaves to remain small, and drop prematurely, resulting in less photosynthesis occurring in the plant, and fewer, smaller tubers can ...
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] Any plant may be affected, but raspberries and pears are particularly susceptible, as well as most acid-loving plants such as azaleas and camellias.
Leaf spots are visible symptoms of virus infections on plants, and are referred to as systemic symptoms. [7] In systematic virus infections leaf spots caused by viruses show a loss of green colour in leaves, due to chlorosis which is a repression of chlorophyll development. [ 1 ]
Molybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: [1] [2] pale leaves with interveinal and marginal chlorosis (yellowing) and necrosis (scald); the whiptail disorder in Brassica crops (especially cauliflower);
Plants with nutrient deficiencies can display an array of symptoms depending on the nutrients they lack. Yellowing leaves with visible, bright green veins and stunted plant growth are common signs ...

Darker green leaves and purplish or red pigment can indicate a deficiency in phosphorus. This method however can be an unclear diagnosis because other plant environment factors can result in similar discoloration symptoms. In commercial or well monitored settings for plants, phosphorus deficiency is diagnosed by scientific testing.
