Lowlight

Light is very important for the growth, development, and metabolism of the plant, and being an important environmental factor, plays a critical role in photosynthesis and photomorphogenesis. Due to increased cloud cover, the problem of low light, both quality and quantity, has become dominant stress in eastern India, causing yield loss particularly to the rice crop.
Low light hinders the physiological metabolic processes such as photosynthesis, antioxidant characteristics, carbon, and nitrogen fixation and greatly inhibits the agronomic traits of plants.
It also decreases the leaf weight as well as flower bud numbers by causing slow growth. Low light causes change in color and extend the maturity time in some plants and also reduces sugar and starch contents in the grain.
The photosynthetic efficiency and stomatal conductance were found to be low in the plants grown under low light conditions as compared to those grown under natural light.
Under the prevalence of low light stress from 5 to 15 days, the relative chlorophyll content, anthocyanin, net photosynthesis rate, transpiration rate, stomatal conductance, and antioxidant activity of plant decreases significantly while malonaldehyde content increased, which damages plant cells.
