| 摘 要： | 研究通过不同浓度的Cd^2＋对玉米萌发影响的测试，结果表明，当Cd^2 浓度为0.5mg/L-1.0mg/L时，Ｃd^2 可以促进玉米种子的萌发，提高玉米的发芽势和发芽率，促进玉米芽与幼根的生长，高浓度的Ｃd^2＋不利于玉米萌发和生长。Ｃd^2 对玉米根生长的影响大于对芽生长的影响。

| Abstract: | The effects of Cd 2 in different concentrations on the germination of maize were studied.It was shown that Cd 2 raised germination percentage with viablity,index of seed vigor,the bud growth and root growth when Cd 2 level was range from 0.5 mg/L to 1.0 mg/L.Hign level Cd 2 was harmful to the germination and growth of maize.Cd 2 has more influence on root growth of maize than on its bud. |
