| 摘 要： | 用GA3处理大麦叶段,在黑暗条件下对叶绿素含量下降无影响,而在光照下有保绿效果。本文就这一现象进行了试验分析,其结果是光的作用在于降低叶内ABA含量,从而减缓叶段内ABA对GA3的拮抗作用。

| Abstract: | GA 3 had little effects in dark condition and an obvious effect in light on retarding the decrease of chlorophyll content in barley (Hordeum vulgare L.) leaf segments. GA 3 had little effect either in light when it was mixed with ABA and applied to the segments. The free ABA content determined by RIA in the segments was obviously lower in light than in dark conditions in the experiment. It was inferred that the different effects of GA 3 on delaying the decrease of chlorophyll content in dark and light conditions was due to the different content of endogenous ABA in the segments in dark and light conditions. |
