Abstract:
Taking Sedum spectabile and Sedum spetabilis planted in pots with cadmium as materials,the absorb and accumulation of Cd in different organs of these two Sedum and the effects of Cd on biomass,height,quantity of leaves and flowers were studied.The results showed that Cd had toxic effect on these two Sedum,decreased plant height,shorter and thinner roots,reduced leaf number,changed leave color,and decreased biomass.With the increase of Cd concentration,Cd content in the organs of both Sedum sp. significantly improved.Cd concentration in different organs from high to low was leaf>stem>inflorescence>root.Cd accumulation above ground was greater than under ground,which indicated that these two Sedum sp.had strong transport capacity,and had the potential for phytoremediation.The results had important significance for the application of Crassulaceae plants in Cd phytoremediation in the northern area.
