In order to study the differences of absorption and accumulation characteristics of heavy metal cadmium(Cd) in different cowpea materials,a preliminary pot experiment was conducted using 12 cowpea materials in Cd contaminated soil.The results showed that, under Cd stress, the biomass of cowpea HF1013-25-2-1-1 in seedling stage was significantly higher than that of other cowpea materials,and its Cd content was also higher.For 7104 in seedling stage,the biomass above ground was the lowest and Cd content was the highest,and the biomass above ground of other cowpea materials was between HF1013-25-2-1-1 and 7104.When cowpeas matured,the first four cowpea materials with high pod biomass were:FA black-black-3-1-green pod>15279>17300>HF1013-25-2-1-1,while the pod biomass of 15282-1 was significantly lower than that of other cowpea materials,and other materials were between FA black-black-3-1-green pod and 15282-1.Cowpea 7104 had the lowest Cd content in pods,and except 7104,there was no significant difference in Cd content of pods among 11 other cowpea materials.Therefore,cowpea FA black-black-3-1-green pod and 15279 with high pod biomass and low Cd content can be given preference to plant in the Cd-polluted areas.
