The ornamental plant,Brassica oleracea L.var.acephala DC.was selected to study characteristics of tolerance and accumulation for cadmium (Cd),aiming to explore its feasibility in phytoremediation.The results showed that:(1)the dry weight of B.oleracea L.var.acephala DC.increased at first and then decreased with increased Cd concentrations,20-80 mg·kg^-1 Cd treatment could promote the growth of B.oleracea.Higher Cd concentration at 100-120 mg·kg^-1 inhibited roots growth significantly,while promoted growth of shoots,and there was no distinctive difference in whole plant,showing that B.oleracea L.var.acephala DC.had strong capability in tolerance,and the tolerance in shoots was higher than in roots.(2)B.oleracea L.var.acephala DC.has higher activities of antioxidant enzymes such as SOD,POD,APX and lower contents of MDA and electrolyte leakage in leaves.But when the Cd concentration exceed 80 mg·kg^-1,the activities of antioxidant enzymes such as SOD,CAT and APX in roots were decreased,and MDA contents and electrolyte leakage increased significantly,induced severe membrane lipid peroxidation damage,this may be one of the reason of higher tolerance for Cd in shoots than in roots.(3)Cd contents in shoots was higher than in roots,and Cd content in plants increased gradually with the increase of Cd concentration,and reached the maximum at 120 mg·kg^-1 Cd treatment,and the highest Cd contents in roots,shoots were 50.15 mg·kg^-1 and 52.01 mg·kg^-1,respectively.The translocation factor were above 1,Cd accumulation amount in shoots was higher than in roots,and the highest Cd accumulation amount of shoots was 343.19 μg·plant^-1.These results indicated that B.oleracea L.var.acephala DC.had strong capability in tolerance,accumulation and translocation of Cd,and it is a preferable phytoremediation germplasm resources in ornamental plant for Cd polluted soil.
