摘要
目的:揭示内源激素与五味子花芽分化的内在联系。方法:以同一株系五味子超短枝顶芽及长枝的腋芽为试材,采用高效液相色谱法,测定花芽分化不同时期内源激素的含量。结果:高浓度的GA3对五味子的花芽分化及雌花形成具有抑制作用;高浓度的ABA可以促进五味子花芽分化和雌花形成;高浓度ZT对五味子花芽及雌花分化亦具有促进作用;低的GA3/ABA值有利于花芽的形成和雌花分化。结论:内源激素与五味子花芽分化存在一定关系。
Objective： To reveal the relation between endogenous hormones and the flower bud differentiation in Schisandga chinensis. Method： Top buds of extremely short branch and axillary buds of long branch in the same plant of S. chinensis were used as material and the contents of endogenous hormones were measured during different periods of the flower bud differentiation with HPLC. Result： The result showed that flower bud differentiation and the formation of female flower were inhibited by high concentration of GA3 and were promoted by high concentration of ABA or ZT. Low ratio of GA3/ABA has the same result. Conclusion： There was a correlation between endogenous hormones and the flower bud differentiation of S. chinensis.
