Kinetics of stress responses to Cd exposure (50, 100 and 200 μM) expanding from 12 to 48 h were studied in roots of hydroponically cultivated-Vicia faba seedlings. The heavy metal induced toxicity symptoms and growth arrest of Vicia roots gradually to the Cd concentration and duration of the treatment. The intracellular oxidative stress was evaluated with the H2O2 production. The H2O2 content increased...
The potential genotoxicity of Cu2+ was investigated in Vicia faba and Pisum sativum seedlings in hydroponic culture conditions. Cu2+ caused a dose-dependent increase in micronuclei frequencies in both plant models. Cytological analysis of root tips cells showed clastogenic and aneugenic effects of this heavy metal on V. faba root meristems. Cu2+ induced chromosomal alterations at the lowest concentration...
