反季节杧果花器官结构对胚胎败育的影响
Effects of Floral Structure on the Embryo Abortion of the Anti-season Mango
摘要
Abstract
[Objective]To research the effects of floral structure on the embryo abortion of the anti-season mango.[Method] We observed the flo-ral organ and embryo structure of anti-season mango,explored the changes of cytology structure of mango cultivar Jinhuang druing embryo abor-tion,and researched the cytological mechanism of embryo abortion.[Result]Jinhuang showed stamen degeneration,there were significant differ-ences in anther development,the bigger anther possessed the more pollen quantity with higher maturity.Only a few pollen in sac showed degener-ation. Pollen activity was 76.9%.In female organs,there were phenomena of ovary atrophy and hemitropous ovule;and the broken transmission tissue was common around the conducting tissue.When the megaspore developed in stage of eight nucleolus,polar nucleus cell disappeared or de-generated in the same or different ovules.[Conclusion] All these factors might affect the fertilization of the ovule,and lead to poor pollination and fertilization.关键词
