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.
目的
揭示五味子内源激素与花芽分化之间的关系。
方法
以五味子同一植株上极短枝顶芽和长枝腋芽为材料，采用高效液相色谱法测定花芽分化不同时期内源激素含量。
结果
结果表明，高浓度的赤霉素（GA3）抑制花芽分化和雌花形成，高浓度的脱落酸（ABA）或玉米素（ZT）促进花芽分化和雌花形成。赤霉素与脱落酸的低比值也有相同效果。
结论
五味子内源激素与花芽分化之间存在相关性。
