| 摘 要： | 采用酶联免疫吸附测定法（ELISA）,在花芽分化期对罗汉果雌株二级蔓上的腋芽（花芽）进行了植物内源激素生长素（IAA）、赤霉素（GA3）、脱落酸（ABA）、玉米素核苷（ZR）含量变化的研究。结果表明：在罗汉果花芽分化进程中,低水平的IAA、GA3和高水平的ABA、ZR可能促进花芽分化;在激素平衡中,ABA/GA3和ZR/GA3比值的变化起主要的影响作用,高比值的ABA/GA3和ZR/GA3可能有利于罗汉果花芽分化。

| Abstract: | During flower bud differentiation of Siraitia grosvenorii,the dynamic variation in contents of plant endogenous hormones IAA,ABA,GA3 and ZR in the female flower bud of second order vine were determined with enzyme linked immunosorbent assay （ELISA）. The results showed that in the developing process of flower bud,low levels of IAA and GA3 and high levels of ABA and ZR could accelerate flower bud differentiation. The changes in ratios of ABA/GA3 and ZR/GA3 played primary roles. High ratios of ABA/GA3 and ZR/GA3 also could promote flower bud differentiation. |
