| 摘 要： | 研究了盆栽试验条件下重金属铬胁迫对芹菜叶绿素含量和抗氧化酶系统的影响。结果表明:低浓度的Cr3+可诱导叶绿素的合成和SOD、POD酶活性的提高,高浓度的Cr3+对叶绿素的合成起破坏作用,降低SOD、POD酶活性。在Cr3+离子浓度为20 mg.L-1时,叶绿素含量达到最高,SOD、POD活性在Cr3+离子浓度为40 mg.L-1达到峰值。MDA含量随着处理浓度的升高,呈升高趋势。

| Abstract: | Effects of heavy metal chromium on chlorophyll content and antioxidant enzyme systems in condition of pot experiments were studied.The results showed that the chlorophyll content,the activities SOD and POD increased under low Cr~(3+)concentration but decreased under high concentration.Chlorophyll content reached the highest point at 20 mg·L~(-1) Cr~(3+).SOD and POD all had a resistant peak at 40 mg·L~(-1)Cr~(3+).An increasing tendency of MDA content appeared with the increasing Cr~(3+) concentration. |
