[Differences in cadmium absorption and accumulation of Brassica varieties on cadmium-polluted soil].
A pot experiment was conducted to study the differences in cadmium (Cd) absorption and accumulation of sixty Brassica varieties on the soils added with different concentration of Cd. The results showed that when the soil Cd concentration was 0.6 mg x kg(-1) and 1.2 mg x kg(-1), the percentage of test Brassica varieties whose Cd content exceeded the National Edible Standard was 8.33% and 66.67%, respectively, suggesting that Brassica was easy to be Cd-polluted. The shoot Cd content of all test varieties was below the National Edible Standard, and the biomass of the varieties Changgengbaicai, Shanghaiqing, Aijisuzhouqing, Qingyou 4, Aijiaokuipianheiyebaicai, Zhouyeheiyoudonger, Gaohuaqinggengbaicai, Zaoshenghuajing, Jinguanqingjiangbai, Xiawangqinggengcai, Lifengqinggengbaicai, and Hangzhouyoudonger was not affected. These 12 Brassica varieties could be planted on the soils with light Cd pollution.
