Abstract:
Drought and waterlogging are the most severe global problems for vegetables. When water is present in excess amount than its optimum requirement it refers to water logging. Drought stress occurs when the accessible water in the soil is concentrated and atmospheric circumstances cause permanent loss of water by evaporation or transpiration. In the water-logged soils, water gets filled in the pores of the soil, so the oxygen concentration decreases in soil. O deficiency decrease growth and survival of plants growing in it. The flooding 2 frequently induces stomatal closing mostly in C3 vegetable plants. Drought results in leaf dehydration; therefore, wilting of leaves occurs due to the limited water flow from the roots to the shoots. Waterlogging and drought affect a number of biological and chemical processes, which can impact crop growth in both the short and long term, in plants and soils. Germinating seeds are very sensitive to water logging and drought as their level of metabolism is high. Plants growing under stress conditions also demonstrate the formation of adventitious roots and formation of aerenchyma. Aim of this review paper is exhibit the vegetable plants responses to the water Logging and Water deficiencies.
