In this work, the changing effect of different concentrations (0, 0.01, 0.1, 1, 10mM) of hexavalent and trivalent chromium on different biochemical parameters along with antioxidant enzymes was investigated on water lettuce (Pistia stratiotes L.) in order to know the possible involvement of this metal in oxidative injury, besides the activities of antioxidant enzymes leading to biochemical and oxidative aberration induced by elevated concentrations. Both in roots and shoots, Cr produced a significant increase in enzymic and non-enzymic antioxidants, except in catalase (CAT) activity where a strong accumulation of hydrogen peroxide was indicated, suggesting an imposition of oxidative stress. The observation showed an uptake of chromium by P. stratiotes L.... |
