Induction of Oxidative Stress in Cyamopsis tetragonoloba, Taub Under Lead and Chromium Phytotoxicity

摘要

Changes in physiological and biochemical characteristics under lead and chromium toxicity were investigated in Cyamopsis tetragonoloba, Taub. Decrease in dry matter and photosyn-thetic pigments were observed in cluster bean under metal treatment. Increase in the activity of enzymatic antioxidants like peroxidase, superoxide dismutase, catalase and polyphe-nol oxidase was observed in both Pb and Cr toxicity. The level of oxidative damage was marked under Cr than Pb, in cluster bean.
