葡萄的花序,在开花后其大部分小花都从小花梗的基部脱落。结实的比率,因品种而异,通常为10—50%。玫瑰香葡萄的花粉萌发率较高而结实性低,易因栽培条件的变化而引起落花。本研究是采用组织形态学的观点,从开花到结果(或落果)的全过程,观察了玫瑰香葡萄的小花,其目的是揭示落果的原因。同时还探讨了摘心、疏花及喷硼等处理对其结果的影响。
The inflorescence of grapes, after flowering, most of its small flowers from the pedicel base off. The sturdy ratio, which varies by breed, is usually 10-50%. Rose grapes pollen germination rate is high and low solidity, easy to change due to cultivation conditions caused by falling flowers. In this study, from the perspective of histomorphology, the flowering to fruiting or deciduous fruit was observed. The purpose of this study was to reveal the causes of falling fruit. At the same time, we also discussed the influence of the processing such as topping, thinning and boron spraying on the result.
