| Popis: | Pot experiments were carried out to investigate the effects of Copper (Cu) and Cadmium (Cd) on Vetiveria zizanioides. Results revealed that increasing metal concentration in growing medium caused reduction in dry biomass, water content, leaf chlorophyll and soluble protein on exposure of Cu and Cd for 30 days. Cu and Cd accumulation in root and shoot enhanced on increasing Cu and Cd concentration in soil and reached a maximum of 514 and 1069 mg kg−1 dry weight (DW) in root and 58.03 and 17.87 mg kg−1 DW in shoot at exposure of 150 and 75 mg kg−1 of Cu and Cd respectively. Results also showed that the exposure of Cu and Cd in combination was more phytotoxic than the individual treatments. However, Bioconcentraion Factor (BCF) was found to be greater than one indicating suitability of V. zizanioides for phytoremdiation of Cu and Cd from soil. Metal accumulation in roots was much higher than shoots (TF ≪ 1) indicating that the mechanism involved was of phytoextraction. |
