Effects of salt stress on Biochemical & Antioxidant Activity in Mung Bean (Vigna radiate)

Abstract

A significant food grain legume with considerable economic importance is the mungbean. For vegans in particular, it is a great source of dietary protein and offers nutritional health benefits. Due to its short lifespan, it plays a crucial part in important farming systems and promotes soil fertility. Due to the mungbean's vulnerability to many environmental stressors, production is still declining. Along with the growing global population and depleting natural resources, salt stress is one of the most pervasive abiotic stresses posing hazards to agriculture food crops. A lesser amount of work has been put on creating a better mungbean cultivar. The present review highlights the detrimental effects of salt stress and the physiological responses in mungbean. Abiotic stress such as salinity, drought, extreme temperature, chemical toxicity and oxidative stress are serious threat to agriculture and natural status of the environment. Salt affects growth of the crop, quality of the crop. Stress in environment which can be natural or induced by human. During salinity condition the length of the root, branches and number of roots hair are decrease. Salt stress cause chlorosis, necrosis & reduced the chlorophyll content in the plant. Salt decrease the osmotic potential of the soil solution. Salinity is the concentration of dissolved mineral salt electrolytes of cations and anions present in the soil and water.The effect of Nacl stress on growth, ion accumulation, content of protein and antioxidant enzymes activity. Nacl stress enhanced the activity of superoxide dismutase and Ascorbate peroxidase & Glutathione peroxidase. Antioxidant enzyme activity could be a response to cellular damage by Nacl. In this study
specific mung genotype RMG-492 was analysed effect of different stress (moderate & severe) on plant growth. the impact of sodium stress on development, ion buildup, protein composition, and antioxidant enzyme function. Superoxide dismutase, ascorbate peroxidase, and glutathione peroxidase all had increased activity in response to a cation stress. Activity of antioxidant enzymes may be a reaction to Nacl-induced cellular damage. In this study, the effects of various stresses (moderate and severe) on the growth of a particular mung genotype, RMG-492, were examined.
