Abstract

To evaluate the capacity of the tolerance mechanisms of plants to metal contamination in the environment, bean seedlings were exposed to two different concentrations (150 and 350 mg L-1) of selected heavy metals (Cu, Mn, Pb, Ni, Cd and Zn). Element analysis (by ICP-AES), and FRAP (Ferric-Reducing Antioxidant Power) assay were performed. Also, RAPD (Random Amplified Polymorphic DNA) analysis was used in order to evaluate the variation at the DNA level. We hope that the results of our research may provide a new insight into understanding metal phytotoxicity and use of plant bio-assays as sensitive tool for detecting genotoxicity.
