调查了郑州市 2球悬铃木花芽分化分布规律 .结果表明 ,悬铃木的雄花芽数量远远多于雌花芽数量 ,二球悬铃木的雌雄花芽中 ,分化成 2球的占 1/2以上 ;雌雄花芽主要分布在树冠外围 ,尤其雌花芽在外围的分布比率更大 ;在小枝上 ,顶侧芽分布的花芽最多 ,而其它位置则相对较少 ,雌花芽的分布更是如此 ,导致顶侧芽的雌雄花芽比率增大 .在小枝上的不同侧芽位置 ,1,2 ,3雌雄球的分化比率不同 ,从顶侧芽向下到侧 3,1,2球雌花芽分化比率有减少的趋势 ,而 3球雌花芽比率有上升的趋势 ,与此对应 ,1,2 ,3球雄花芽在各侧芽上的分化比率基本保持不变
The results showed that the number of male flower buds in Platycladus orientalis was much more than that of female flower buds and the number of male and female flower buds in Platycladus orientalis was more than half that of two flower buds, Especially in the periphery of female flower buds. In the branchlets, the top buds distributed the most flower buds, while the other positions were relatively less, especially in the female flower buds, which led to the male and female flower bud ratio Increased in the different branchlets on the branch position, 1, 2, 3 male and female ball differentiation rate is different from the top side of the bud down to the side 3,1,2 ball female flower bud differentiation rate has decreased, and 3 ball female flower bud The rate of increase has the trend, corresponding to this, 1, 2, 3 ball male flower bud differentiation rate in each side bud remained unchanged
