在前人关于板栗(Castaea mollissima BL.)花芽形态解剖研究的基础上,作者进一步对其生殖器官的发育和分化进行了系统的解剖学研究。本文描述了板栗的雌雄花花器各部、雌雄配子体、受粉受精、胚胎和果实发育分化阶段及时间,并明确了板栗刺苞的外被和果实各部结构的胚胎来源。根据研究结果,讨论了板栗花的性别比例的调控和产量构成影响因子等问题。
Based on the previous studies on the morphological anatomy of flower buds of chestnut (Castaea mollissima BL.), The author further systematically studied the development and differentiation of reproductive organs. This paper describes the stages and timing of development and differentiation of chestnut male and female flower units, male and female gametophytes, fertilization, embryo and fruit development, and clarifies the embryo origin of the outer coat and the fruit structure of the chestnut spines. According to the results of the study, the regulation of the sex ratio of chestnut flower and the influencing factors of yield composition were discussed.
