摘  要：
果树生殖生物学研究是果树栽培生理和遗传学研究的重要内容之一,了解并掌握果树生殖生物学特性对于果树遗传研究与品种改良具有积极的指导意义。作为我国重要的干果之一,迄今,已经对板栗的生殖生物学特性进行了大量研究,掌握了其授粉结实特性,揭示了花芽分化过程以及内源激素等对花器官发育的调控机制,探明了授粉受精、营养元素及有性生殖过程中胚胎发育异常等因素与板栗空苞的相关性,雄性不育研究也取得了初步进展。根据板栗生殖生物学研究取得的成果,本文从花特性、花芽分化、开花授粉生物学特性以及板栗空苞现象等方面进行了概述,重点总结了板栗花芽分化与花性别分化及其机理、板栗空苞及其发生机理,以及板栗雄性不育等方面的研究进展。并根据目前的研究现状,对该领域今后的发展趋势进行了展望。

摘  要：
Reproductive biology of fruit tree is a crucial part of cultivation physiology and genetic research.Understanding the characteristics of fruit tree reproductive biology provides a window for genetic research and cultivar improvement.Castanea mollissimma,as one of China's important dried fruits,so far,has done a lot on its reproductive characteristics.The studies interpret the nature of pollination,flower bud differentiation and endogenous hormone action during flower organ development.And these also perceive the relationship between abnormal embryo development and the empty shell of chestnut at different case of pollination and fertilization,nutrient,abnormal embryo development and sexual reproduction.An initial progress has also been made in male sterility.The paper features from flowers,flower bud differentiation,flowering and pollination biology characteristics of chestnut and other aspects of the phenomenon of empty shell,also gives an overview summary of the flower bud differentiation and focus on sex differentiation and its mechanism,chestnut empty shell and principle,and research advance about male sterility.Based on the current research status,future trends in this field were discussed.
