Abstract:

Water deficit and salt stresses are global issues related to survival of agricultural crops and sustainable food production. Drought stress occurs when the available water in soil is reduced and atmospheric condition cause continuous loss of water by transpiration and evaporation. The general complexity of drought is often aggravated under conditions of erratic and unpredictable rainfall and by the occurrence of high temperature, high levels of solar radiation and poor soil characteristics. A key to progress towards breeding for better crop varieties under drought stress is to understand the biochemical, physiological and molecular machinery that are induced under such stress. The present experiment was envisaged to i) study the effect of drought stress on seedling growth of few genotypes of mungbean and to rank them on the basis of their tolerance and ii) study the physiological and biochemical changes in selected tolerant and susceptible genotypes to have an understanding of physiological basis of drought tolerance. The drought stress was imposed using a solution of polyethylene glycol (PEG) 6000 creating an osmotic potential of -1.5 MPa. A control set containing distilled water was also prepared for comparison. The higher activities of ROS scavenging enzymes, SOD, GPOX and catalase helped the tolerant genotypes to combat against drought-induced oxidative stress in much better way than the susceptible ones.
