摘要: 本文研究了“早玫瑰”和“新玫瑰”葡萄胚珠、胚乳和胚的发育。结果表明:花后3天胚珠即开始迅速生长,共生长的最终大小依品种成熟期的不同而各异。 胚乳游离核在花后33天成为细胞状态。受精后16—21天,合子才开始第一次分裂。当胚乳充满珠心组织时,胚开始迅速发育并—直持续到果实成熟。胚的发育与果实的发育无明显竞争关系。

Abstract: This paper deals with the development of the ovules, endosperms and embryos of “Early-muscat” and “Neo-muscat”. The results were as follows: (3-days after anthesis) The ovules of the two cuhivars began to grow .quickly. Their final sizes depended on the ripening-time of the cultivars. (33 days after anthosis) The endosperms became cell. The zygotes didn’t divide until 16-21 days after anthesis. When the nucelli were filled with endosperms, the embryos began to develop quickly and continued until the ripeniog of the fruit. The development of embryos had no obvious competition with the development of their fruit.
