The world faces significant challenges such as climate change, floods, population growth, and various environmental stresses. All of these can directly or indirectly affect agriculture. Drought is one of the most important abiotic stresses and a limiting factor in the successful production of plant products worldwide and has adverse effects on plants' morphological and physiological activities. Adaptation to the impact of drought stress results from changes in growth, and physiological and biochemical mechanisms that cause changes in growth rate, stomatal conductance, photosynthetic process, and enzymatic activities of plants. Drought stress disrupts photosynthesis in plants and gradually reduces carbon dioxide uptake due to closed stomata. In addition, drought stress affects the stability of cell membranes and disrupts plant water relationships by reducing water use efficiency. Plants adopt different mechanisms to deal with these conditions. Proper management is essential to prevent the adverse effects of drought stress. Today, researchers are trying to reduce the impact of drought stress by spraying the plants with hormones or hormone-like compounds, growth-promoting bacteria, mycorrhizae, and selecting resistant cultivars. This paper investigates the effects of drought stress on plants' morphological, physiological, and biochemical characteristics. Also, some crop management methods have been reviewed to overcome the destructive effects of drought stress. [ABSTRACT FROM AUTHOR] |
