| 摘 要： | 为探讨铜对植物的毒害机理,研究了不同浓度铜对萝卜种子萌发及幼苗生长的影响.研究结果表明,随着铜浓度的增加,萝卜种子的发芽率、幼苗株高和根长都受到抑制.超氧化物歧化酶(SOD)和过氧化物酶(POD)活性随着铜浓度的增加先升高后降低.

| Abstract: | A study was made to explore effects of copper on the germination and seedling growth of radish. The results showed that the germination rate, plant height, root length were restrained. The activity of superoxide dismutase and peroxidase rised firstly then fell with concentration of copper increased. |
