A study was carried out to identify the mechanisms underlying stress caused by Cd and Pb accumulation in leaves of Atriplex halimus L. collected from habitats representing different kinds of pollution. Mean concentrations of Cd and Pb in aerial parts exceeded the critical levels in polluted plants
Beside a direct toxicity, cadmium impact on plants involves both a secondary-induced water stress and an oxidative stress. Proliferating cell lines of Atriplex halimus were selected for their sensitivity or resistance to polyethylene glycol (PEG 10,000, 20%) and then exposed to 100 microM CdCl2 in
The xero-halophyte Atriplex halimus L., recently described as Cd-hyperaccumulator, was examined to determine Cd toxicity threshold and the physiological mechanisms involved in Cd tolerance. An experiment was conducted to investigate the effect of cadmium from 0 to 1350 μM on chlorophyll fluorescence
