| 摘 要： | 对卷柏和圆枝卷柏在干旱胁迫条件下,叶片相对含水量、质膜透性、丙二醛含量(MDA)、叶绿素含量及超氧化物歧化酶活性(SOD)5项指标进行了比较研究。结果表明:随着干旱胁迫天数的增加,2种植物的叶片相对含水量均呈下降趋势,质膜透性、丙二醛含量均呈上升趋势,叶绿素含量不同程度下降,SOD活性先上升后下降,其中圆枝卷柏出现拐点的时间早于卷柏。综合分析表明,卷柏比圆枝卷柏更抗旱。

| Abstract: | The comparative study was conducted on drought stress of Selaginella tamariscina and Selaginella sanguinolenta.The results showed that in the periods of drought stress of two plants,conductance rate and MDA content both rise,while chlorophyll content decrease,and SOD activity rise firstly and decrease finally,however Selaginella sanguinolenta decrease eariler than Selaginella tamariscina.And chlorophyll content and SOD activity could be used as Selaginella tamariscina and Selaginella sanguinolenta drought r... |
