Corn grey leaf spot can be an extremely devastating disease as potential yield losses range from 5 to 40 US bushels per acre (440 to 3,480 L/ha). At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.
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.
Often, plants that have wilt symptoms also have leaf blight symptoms. [citation needed] The second, more common phase of the disease is the leaf blight phase, which occurs on the leaves at any vegetative growth stage. [3] At first, the leaf lesions appear long and irregularly shaped and are light green to yellow and later on, straw colored.
This guide explains the most common reasons for peace lily leaves turning yellow and provides simple tips to help your plant recover. 1. Watering Stress. Overwatering and underwatering are, hands ...
Young leaves, may experience chlorotic spotting which may eventually turn into a mosaic or mottle pattern (“Maize Dwarf Mosaic Virus,” n.d.). Later in the growing season, the mosaic pattern may bleed into a general yellowing of the leaf and eventually areas of red streaks or blotches may appear if night time temperatures are consistently ...

Many plants lose much of the remaining energy on growing roots. Most crop plants store ~0.25% to 0.5% of the sunlight in the product (corn kernels, potato starch, etc.). Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about ...
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 ...
