木荷的开花结实特性

Characteristics of the Flowering and Breeding of Schma superbe

野外定位观测木荷的自然生境、开花进程、结实状况等内容 ,结果显示 ,木荷的花枝通常有 3 -1 1朵花 ,花单独腋生或数朵聚生于枝顶。 6月初开花 ,花期 40天左右。单花花期 5 -7天 ,第 2天柱头进入可授期 ,同时花药开裂散发出花粉 ;第 5天 ,花瓣开始脱落 ,而花柱在 2 0天左右脱落。木荷的结实率很高 ,平均为 94.8%左右 ;开花时间和开花顺序对结实率没有明显的影响 ,但对于果实的发育及种子的形成有一定的影响。

The natural habitat, flowering progress, and breeding status of Schma superbe were observed in fieldwork. The results show that there are 3-11 flowers in an inflorescence. Some of them are axillary individually and others are collected together in the top of the inflorescence. It flowers at the beginning of June, lasting for 40 days. The florescence of a single flower is 5-7 days. On the second day of florescence, the chapiter can accept pollen while the anther splits and the pollen is emitted. On the fifth day, the petal falls off while the style falls off 20 days later. The breeding rate of Schma superbe is high, with the average rate being 94.8% or so. The time and the order of flowering have no distinct influence on the breeding. But they have definite influence on the development of fruit and the forming of seed.
