ABSTRACT

This chapter explains the study of pot experiment to determine if the application of exogenous selenium (Se) can alleviate cadmium (Cd)-induced plant growth inhibition, Cd uptake, and Cd distribution and translocation. Some studies have shown that Se can significantly reduce the accumulation of Cd in rice shoot but has no significant effect on the accumulation of Cd in the root. However, in this study, most of the Cd absorbed by plants was accumulated in shoots, and the distribution ratio of Cd in radish shoots increased with the increase of Se level, indicating that Se application promoted the distribution of Cd in shoot. The application of Se at the appropriate concentration (1 mg/kg) into the soil can reduce the accumulation of Cd in plants, and the application of exogenous Se can regulate the transport of Cd in crops. However, the mechanism of Se inhibiting Cd in plants still needs to be further explored.
