Results showed that shoot biomass of H. annuus was significantly higher than that of R. acetosa and R. hastatus ; among 3 plant species, Cs specific activity in shoots was the highest in H. annuus after treatment for 50 days, however after treatment for 70 days, that in R. acetosa was the highest. Bioaccumulation ratio reached 115, 114 and 113 in R. acetosa, R. hastatus and H. annuus at the end of experiment, respectively, and the former two plants kept with trend of continuously increasing during the experiment period. Three plants were tolerant to Cs contaminated soil and capable to translocate Cs from soil to plants. Among them, H. annuus removed greatest Cs amount in the above ground part, and R. acetosa, R. hastatus showed higher tranclocation factor of Cs than H. annuus. Three plants are promising for phytoremediation of soil contaminated with radiocesium, and also could be used for phytoremediation of radiocesium and heavy metals complex contamination, potentially. : : :( G ) : (19772),,,, Tel : ; E2mail : (19632),,,,,E2mail com
