| 摘 要： | 目的]研究水体镉污染对绿豆种子萌发及幼苗生长的影响,为绿豆高产优质栽培提供理论依据。方法]采用不同浓度（0、1、5、30、100 mg/L）的CdCl2溶液模拟水体镉污染,研究其对绿豆种子萌发及幼苗生长的影响。结果]高浓度的Cd2＋明显抑制绿豆种子的萌发及幼株的生长,并导致幼苗可溶性糖、可溶性蛋白含量降低,游离脯氨酸含量提高。质膜透性增强,随着Cd2＋浓度的升高,SOD活性先升高后降低,POD活性逐渐升高。结论]高浓度的Cd2＋对绿豆幼苗具有明显的毒害作用。

| Abstract: | Objective] The aim was to study effect of water cadmium pollution on germination of mung bean seed and seedling growth and provide theoretical foundation for high quality cultivation of mung bean.Method] Effect of different concentrations(0,1,5,30,100 mg/L)cadmium solution which simulated the water cadmium pollution on germination of mung bean seed and seedling growth was studied.Result] The result showed that high concentration CdCl2 solution obviously inhibited germination of mung bean seed and seedlin... |
