Abstract
The possible role of Zn and Cr as catalytic inducers of free radicals in wheat leaves was investigated. Treatment of excess heavy metals decreased the chlorophyll and carotenoid content in wheat leaves with the increase in time of excision. A sharp increase in proline accumulation was marked with the increase in metal concentration. Total peroxide content and lipid peroxidation measured as malondialdehyde content showed uniform increase under metal treatment in excised leaves. At almost all concentrations, catalase, guaiacol peroxidase and superoxide dismutase activities decreased with a minor increase in the earlier days of excision. Though glutathione content decreased ascorbate content showed significant increase in wheat leaves under heavy metal treatment.
