植物花芽的发育与内源激素关系密切。以芍药品种大富贵休眠期花芽为材料，采用高效液相色谱技术（ HPLC）分析内源激素GA3，IAA，ZT，ABA在芍药休眠芽发育不同时期的含量变化。结果表明：ABA含量在北京地区11月20日开始增加，12月10日达到最大；GA3含量12月10日开始明显上升，12月30日开始下降；ZT与GA3含量变化基本一致；IAA在休眠过程中含量很低且变化不大；GA3/ABA和ZT/ABA的比值随休眠的加深而减小，随休眠的解除而增大。研究证明GA3和ZT是解除休眠的促进物，这一结果对于施用外源激素打破芍药休眠具有理论指导意义。

The growth of flower buds of plants is closely related to the endogenous hormones .This paper examined the buds of Paeonia cultivar Da Fugui in the period of dormancy .The content variation of the GA 3 , IAA, ZT, ABA in different periods of dormant bud development of Chinese herbaceous peony were measured by using the liquid chro -matography technique .The results showed that ABA content started to increase on November 20th, reached the peak on December 10th;GA3 content increased obviously on December 10th and decreased on December 30th;ZT content had a similar trend to that of GA 3 .However , the IAA content was relatively low with little fluctuation in the dormant period.GA3/ABA and ZT/ABA values decreased with the deepening of dormancy and increased after the release of dormancy .The study indicated that GA 3 and ZT can promote the release of dormancy , which has the theoretical guid-ing significance for the release of dormancy with the application of exogenous hormones .
