| 摘 要： | 目的]分析和研究不同Cd浓度处理对芦蒿生理代谢的影响。方法]以芦蒿（Artemisia seleirgensis）为试验材料，研究了不同浓度Cd处理对丙二醛（MDA）含量及超氧化物歧化酶（SOD）和过氧化物酶（POD）活性的影响。结果]结果表明，Cd污染会导致芦蒿氧化胁迫，膜脂过氧化作用随着Cd处理浓度的增加而加剧；低浓度Cd（〈30μmol／L）胁迫下，芦蒿体内的保护酶系统SOD和POD的活性都呈上升的趋势，表现出一定的抗逆性，但是随着Cd浓度（≥50μmol／L）的增加，SOD活性开始下降，而POD活性仍然呈上升的趋势。结论]MDA和保护酶（SOD和POD）能灵敏地反映芦蒿受Cd污染的情况，为环境检测中评价芦蒿被Cd污染的程度提供理论依据。

| Abstract: | Objective] The research aimed to study the effects of different concentrations of cadmium(Cd) on the physiological metabolism of Artemisia selengensis.Method] The effects of Cd on the content of malondialdehyde(MDA) and the activity of superoxide dismutase(SOD) and peroxidase(POD) in leaf of Artemisia seleirgensis were analyzed after treated by Cd.Result] The results showed that the lipid peroxidation in leaf strengthened with the increase of Cd concentration in the culture.When the Cd concentration was ... |
