| 摘 要： | [目的]研究Fe2＋对人参（Panax ginseng Meyer）叶中防御酶活性和丙二醛（MDA）含量的影响。[方法]采用叶面供Fe2＋的方法。试验共设5个处理,Fe2＋浓度分别为：0（对照）、0.005%、0.050%、0.500%、2.000%。[结果]随着供Fe2＋水平的升高,MDA含量先降低后升高,过氧化物酶（POD）活性呈持续上升趋势,过氧化氢酶（CAT）活性先升高后降低,超氧化物歧化酶（SOD）活性呈先升高后降低再升高的趋势。[结论]从生理角度揭示了铁元素在人参生长发育中的作用机理,为人参的合理施肥提供理论参考。

| Abstract: | [Objective] The research aimed to study the effects of different Fe2+ levels on MDA content and the activity of endogenous protective enzymes in Panax ginseng Meyer leaf.[Method] The foliar application of Fe2+ was carried out.5 treatments were designed,and the concertration of Fe2+ was 0(CK),0.005%,0.050%,0.500% and 2.000% respectively.[Result] The results showed that with the increasing of Fe2+ level,MDA content decreased firstly and increased subsequently,the activity of peroxidase(POD) was increased cons... |
