Abstract

By contrast, tolerance and enrichment characteristics of two species of Sedum alfredii Hance under hydroponic experiment,the maximum Cd content in non mining ecotype Sedum alfredii Hance in shoot and root were 198.93 and 882.64mg/kg, the maximum Cd content mining ecotype Sedum alfredii Hance shoot and root were respectively 5642 and 650.72mg/kg. the enrichment and tolerance of mining ecotype Sedum alfredii Hance has stronger than non mining ecotype Sedum alfredii Hance. This provides a basis for the use of repairing cadmium polluted soil of Sedum alfredii hance.
