摘要: 外界铜胁迫会植株硝酸盐含量减少,NR活性和Vc含量也有类似变化,而可溶性蛋白含量先是略有增加,铜浓度较高时则显著减少,可溶性糖含量也会上升,但超过一定浓度又会呈现明显的下降趋势。

Abstract: Copper stress led to the reduction of nitrate content of plants. Nitrate reductase (NR) activity and vitamin C showed in negative correlation of copper stress.The contents of soluble protein lightly increased, then declined distinctly under the higher concentration of copper stress.The contents of soluble sugar increased in low-copper solution, then reduced when the copper concentration is above the certain degree.
