摘　　要：Germiantion of Brassica chinensis L. grown in the solution with different concentrations of lead, cadmium and chromium (single and combinative) was investigated. Root lengths decreased with the increase of lead, cadmium and chromium in hydroponic solution. The physiological toxicity order for these three ions was Cr 6+ >Cd 2+ >Pb 2+ . The uptake of Pb by Brassica chinensis was enhanced with Pb addition. The toxicity of Cr and Pb was reduced due to precipitation of Cr 2O 7 2- and Pb 2+ . The toxicity of Cd to plant decreased when Cr 6+ was added.
