摘要：The present investigation reports the results of Sn (tin) accumulated by Cyperussp. in a pot experiment on different levels of Sn supply (0, 0.5, 2, 6, 25, 60 mg/kg). All tested Cyperus species showed the different abilities to remove Sn which depend on species and concentrations level. Sn accumulated by the leaves, twigs and roots linearly increased with increasing Sn supply levels. The higher concentration Sn treatments significantly promoted the Sn accumulation. Cyperus rotundus L performed the stronger ability of Sn accumulation under different Sn supply treatments, while Cyperus alternifolius and Cyperus fastigiatus Rottb. had the poorer accumulation ability. Sn in soil was more intensively absorbed in the leaves and twigs for all three C. species, was not retained in roots and was transferred to plant tissues above the ground. The results indicated that Cyperus Sp. have excellent potential for Sn phytoremediation because of their high accumulation ability.
