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.
The most visible symptoms of P. manshurica are pale green to light yellow spots that enlarge into pale to bright yellow lesions of variable size and shape. Lesions later turn grayish-brown to dark-brown with a yellowish-green margin that may eventually become entirely brown.
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]
Veins are pinnate and conspicuous. Leaves have a smooth texture above and hairy texture below. The upper side of the leaves are dark green and the undersides are pale green. Flower: The flowers are monoecious, meaning that both sexes are found on a single plant. Male (Staminate) catkins are 1.6-2.4 in long; female (Pistillate) catkins are 1/2 ...

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 ...
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 ...
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]
