Accumulation and Transfer of Cadmium Isotope (112Cd) by Sonchus asper Intercropped with Vicia faba and Implications for Phytoremediation.

In this study, Sonchus asper and Vicia faba were planted side by side in soils amended with arbuscular mycorrhizae, and 112Cd was applied to either Sonchus asper or Vicia faba planted soils while the neighboring plant received 112Cd across a nylon net impermeable to the roots. Mean concentration of 112Cd in the shoot of Sonchus asper was 7.0 times higher than Vicia faba. The translocation factor of 112Cd in Sonchus asper were 39 and 400 times higher than in Vicia faba under the 112Cd direct and indirect treatments, respectively. The results suggested that the intercropping of Sonchus asper as a hyperaccumulator with Vicia faba, might be a feasible approach for phytoremediation of Cd contaminated soil.
