以3种小白菜为试验材料,探讨了乙二胺四乙酸(EDTA)对镉胁迫下小白菜幼苗保护酶活性的影响。结果表明：外施一定浓度的 EDTA 后,可以缓解镉胁迫对小白菜造成的伤害；当 EDTA 浓度为7.5 mmol·L-1时,小白菜 SOD、POD 酶活性最高,MDA 含量最低；当 EDTA 浓度为5 mmol·L-1时,CAT 酶活性最高；不同品种抗性表现不同,供试的3种小白菜品种中,抗热605的抗性最强。

Three species of Brassica campestris L.chinesis were used in this study to learn the effects of EDTA on the protective enzymatic activities of seedling under cadmium stress.The results showed that EDTA reduced the hurt from cadmium stress under special concentration. When the EDTA concentration was 7.5 mmol·L-1 ,the activities of SOD and POD were at their highest level and the content of MDA was the lowest.When the EDTA concentration was 5 mmol·L-1 ,the activity of CAT was the highest.Different species showed different reactions to cadmium stress,among which kangre 605 was the best during three species.
