ROS Scavenging and Nitrate Reductase Enzyme Activity in Mungbean [Vigna radiata (L.) Wilczek] under Drought Stress

Abstract

Plants are frequently exposed to different types of stress, viz., drought, low temperature, salinity, flooding, heat, heavy metal toxicity etc. Generally drought stress occurs when the available water in soil is reduced and atmospheric condition cause continuous loss of water by transpiration and evaporation. Water deficit and salt stresses are global issues to ensure survival of agricultural crops and sustainable food production (Jaleel et al., 2009). Of the total cultivated area of 1600 million hectares in the world, about 1300 million hectares (80 percent) are rainfed (FAO, 2011). Although rainfed agriculture produces about 60 percent of global crop output in a wide variety of production systems, but the areas under this system is very much prone to drought stress due to International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 04 (2018) Journal homepage: http://www.ijcmas.com
