| 摘 要： | 目的]研究Zn^2＋对滴水观音（AL0cAsIA RHIZOME）抗氧化性系统的影响。方法]采用水培法。结果]在低浓度Zn^2＋胁迫下滴水观音叶片过氧化物酶（POD）、超氧化物歧化酶（SOD）和过氧化氢酶（CAT）活性有一定的增加，但CAT活性在Zn^2＋浓度超过5mg／L时迅速降低。在高浓度Zn^2＋作用下植株叶片POD、SOD和CAT酶活性均快速变化。这表明低浓度Zn^2＋可促进滴水观音生长，而高浓度Zn^2＋则抑制植株生长。结论]可以将滴水观音用于净化低浓度含Zn^2＋废水。

| Abstract: | Objective] The research aimed to study the effects of Zn2+on antioxdation system of ALOCASIA RHIZOME.Method] The solution culture method was used to do the experiment.Result] The results showed that POD,SOD and CAT activities of ALOCASIA RHIZOME leaves had increased with stress of low Zn2+ concentration,but CAT activity had reduced soon when Zn2+ concentration exceeded 5 mg/L.POD,SOD and CAT activities of ALOCASIA RHIZOME leaves had changed quickly with the effects of higher Zn2+ concentration.Low Zn2+ c... |
