MODULATION OF ANTIOXIDANT ENZYME ACTIVITY IN VIGNA RADIATA BY POLYETHYLENE GLYCOL (PEG): INSIGHTS INTO CELLULAR DEFENSE MECHANISM
AbstractThe physiological and biochemical changes in plants are affected by water deficiency caused by polyethylene glycol (PEG). It is a synthetic, water-soluble polymer and induces water deficit conditions. Its application is useful to induce drought stress in different plant varieties. The purpose of this study is to understand the effects of different concentrations of polyethylene glycol on the antioxidant system of Vigna radiata seeds. The polyphenol oxidase, peroxidase and proline content increased with the increment of water stress induced by polyethylene glycol. Enhanced activities of antioxidants could either be a response to the cellular damage induced by the stressors or a mechanism towards the damages. Obtained results of this research indicated that the activities of PPO, POD and proline had significant increase in the plants under the treatment of PEG.
