| 摘 要： | 用溶液培养的方法研究了铜离子对青菜幼苗生长的影响及铜在植物体内的分布和积累情况。结果表明:3μmol/LCu2+即显著抑制根系的伸长,10μmol/LCu2+抑制青菜地上部生长,与对照相比,10μmol/LCu2+处理并不能显著降低根系生物量;5μmol/LCu2+处理,叶绿体色素的含量显著降低,10μmol/LCu2+使叶绿体色素的含量减少为对照的60%;青菜根系铜含量远大于地上部,且随着铜离子处理浓度的升高,根系和地上部的铜含量显著增加。

| Abstract: | Hydroponic cultures were conducted to investigate the copper toxicity in the growth of cabbages seedlings. Experiments were also carried out to study the absorption and distribution of copper in cabbages.The plants showed sensitive to copper. Three μmol/L Cu~(2+) can restrict the root growth of cabbages and decrease of chlorophyll and carotenoid in cabbage leaf. There was higher copper concentration in cabbage root, but lower in shoot. Copper concentration in plant roots and shoots increased with the increment of copper concentration in solution.. |
