Accumulation of chromium and its effects on physiological and biochemical parameters of Alternanthera philoxeroides seedlings

The results from the present experiments suggest that high concentrations of Cr cause oxidative damage as evidenced by increased antioxidative enzymes, photosynthetic pigments and changes in total soluble protein content. Induction of antioxidative enzymes could the reason for tolerating higher levels of metals by A. philoxeroides plants.
