A newly-discovered cadmium hyperaccumulator-red leaf beet (Beta vulgaris L. vat. cicla L)

摘要：

A pot experiment was arranged with various Cd concentrations to study Cd tolerance, accumulation of red leaf beet (Beta vulgaris L. var. cicla L) and its potential for phytoremediation. Results showed that the average concentration of Cd in shoots of red leaf beet with 20mg/kg (Cd) treatment was more than the accepted critical concentration of 100mg/kg. Both enrichment coefficient (EC) and translocation factor (TF) were higher than 1. Moreover, compared with the control, the growth of red leaf beet in the treatment of 20mg/kg (Cd) was not inhibited. So, red leaf beet was a cadmium hyperaccumulator and could be applied to remediate Cd contaminated soils.
