THE EFFECT OF CADMIUM EXCESS ON LIPID PEROXIDATION AND ANTIOXIDANT DEFENCE SYSTEM IN WHEAT SEEDLINGS

The objective of this study was to investigate the changes in some biochemical indices and the changes in antioxidant enzyme activities in wheat seedlings in presence of different amounts of cadmium. Two varieties of wheat were studied (Triticum aestivum L.cv. Dropia and cv. Alex) Obtained results illustrate that cadmium uptake was positively correlated with antioxidant enzyme activities, lipid peroxidation, proline and phenols content. Measurement of oxidoreductase activity, especially peroxidase and studied biochemical indices might be used as biomarkers to asses the phytotoxicity for wheat grown on cadmium contaminated media.INTRODUCTIO
