Changes in crop physiology under drought stress: A review

Abstract

In plants, usually the drought stress in considered as the lowering in the rate of respiration or decrease in the level of the photosynthesis. This review tells us the latest information about the drought stress and its effect on growth of plant with relation to the photosynthesis and water and the mechanism of adaptation. There are numerous ways of mechanism of adaptation that allows the plant to tolerate the drought stress condition. By this review we can proves the statement of different authors on the tolerance of drought stress and the slight changes in the environment conditions may lead to the fast flexibility of the cell metabolism is the first and main step in the avoidance of drought stress.
