| 摘 要： | 研究了不同生长时期燕子掌叶和花中SOD的含量及不同环境因子下燕子掌叶中SOD的含量。结果表明:随着燕子掌由营养生长向生殖生长转变,叶中SOD的含量会升高,花比叶中含量高;在不同盐浓度、水分、光照处理下,燕子掌叶中SOD的活性会随着3种处理水平的增加而升高到一定峰值后下降;3种环境因子对燕子掌的影响程度由大到小依次是盐光照水分。

| Abstract: | The content of SOD in Crassula portulacea leaves and flowers and the effects of NaCl,water,light treatment on SOD in leaves were studied.The results showed that SOD in leaves increases with transformation from vegetative stage to reproductive stage and SOD in flowers were more than leaves.Under the different treatments of NaCl,water and light,the content of SOD increased with the increasing of levels of treatment,and decreased after a maximum.The sequence of three treatment effects on Crassula portulacea wa... |
