چکیده انگلیسی
Hydroponic experiment was carried out to investigate the effect of cadmium (Cd) on growth, Cd accumulation, lipid peroxidation, antioxidative enzymes, leaf chlorophyll, root activity, protein content and Cd uptake kinetics of vetiver grass. The results showed that 1Â mg/L Cd in solution led to increased chlorophyll contents, root activity and enhanced the growth of vetiver grass after 15Â days, with 2.2% biomass increased compared to the control. Malondialdehyde (MDA) contents were significantly enhanced by all Cd supply levels. The development of toxic symptoms corresponded to a high accumulation of Cd and to the decrease of water content, chlorophyll, protein content and root activity, but to high increase in catalase and peroxidase activities in plants. Cd concentration in shoots and roots increased with increasing Cd supply levels, and reached a maximum of 93 and 2232Â mg/kg Cd dry weight at 30Â mg/L treatment, respectively.
