| 摘 要： | 研究了Ｃｄ＾２＋胁迫对玉米幼苗生长和生理生化的影响。结果表明，随着Ｃｄ＾２＋浓度的增加和Ｃｄ＾２＋毒害时间的延长，ＳＯＤ和ＣＡＴ活性降低，ＰＯＤ活性增强，蛋白质含量下降，膜脂过氧化作用加剧（ＭＤＡ含量上升），质膜透性增大，幼苗的生长受到抑制。

| Abstract: | This study showed that increasing the concentration
of Cd2 and prolonging toxic time of Cd2 could reduce protein content and the activity of SOD
and CAT, increase MDA content and the activity of POD, also increase the permeability of
membrane. But, the growth of seedling was inhibited. |
