Physiological Responses of Drought stress in Tomato:A Review



Tomato has important role in food and commercial utilization in the whole world. It is an undetached part of food due to its taste and nutritional value. It is full of minerals, vitamin and antibiotic characteristics. Climate change produces so many natural hazards such as abiotic and biotic stress in the plant. Drought is an important natural phenomenon which affects morphological, physiological, biochemical and yield attributes of plants leading to death. During water stress many physiological and molecular processes are disturbed such as root-shoot growth, water relation, mineral absorption, leaf expansion and orientation, stometal behavior, transpiration rate, photosynthesis and respiration rate, solute translocation, etc. Toxic elements such as reactive oxygen species (ROS) produced during stress period create oxidative damage to the cellular organization. Plants have its antioxidant system to scavenge such harmful element and accumulate osmoprotectants such as proline, glycien betaine, etc to maintain osmotic adjustment. All these and many more aspects have been discussed in case of tomato plants in this review.
