Effects of Chromium (VI) on Groundnut (Arachis Hypogeae L.) Metabolism

Chromium is fairly abundant in earth’s crust and enters in biotic components of ecosystem in various ways. Cr (VI) is highly reactive and influences both plants and animals. A glasshouse experiment was conducted with 0.05, 0.1, 0.2, 0.4, and 0.5 mM of Cr to assess the Cr accumulation pattern and its influence on growth, activities of antioxidant enzymes, relative water content, electrolyte leakage and lipid peroxidation in groundnut (Arachis hypogeae L.) cv. Kaushal plants. In groundnut Cr at 0.5 mM supply caused visible lesions as chlorosis and wilting of mature leaves.
