| 摘 要： | 以一年生扶芳藤(Euonymus fortunei Hand.-Mazz.)扦插苗为材料,以不同浓度NaCl溶液对材料进行处理,观测分析盐分胁迫对扶芳藤幼苗生理效应的影响。研究结果表明,在NaCl溶液处理后,扶芳藤叶片电导率与盐液浓度的大小没有呈现出相关规律;在受到盐胁迫时扶芳藤叶片的SOD活性总体高于对照;POD酶活性总体呈现先降后升的变化趋势;盐胁迫下,扶芳藤叶片内的MDA含量与盐浓度的高低无明显规律。

| Abstract: | Cutting seedlings of the annual Euonymus fortunei Hand.-Mazz.were treated with various concentrations of NaCl solution to study the physiological effect under salt stress.The results showed that under the salt stress,the conductance rate had no relation with the solution concentration.The SOD activities of Euonymus fortunei Hand.-Mazz.were higher than that of control.The POD activities appeared the trend that descending firstly then ascending.The MDA contents in leaves of Euonymus fortunei Hand.-Mazz.had no regularity with the different concentrations. |
