| 摘 要： | 紫李子的花粉发育及胚珠，胚囊的形成，是在春季萌芽过程中完成的．在花粉的发育过程中，花粉母细胞形成阶段较长，减数分裂期较短．在减数分裂期，第１次减数分裂后，在两个子核之间不产生细胞壁，不形成子细胞。第２次减数分裂后，４个子核之间产生细胞壁，形成四分体。花粉发育的同时，胚珠胚囊形成，各个发育时期与花芽的外部形态存在着密切的相关注。

| Abstract: | The development of pollen and the formation of ovult and embryo sac ofplum were finished follovving shcot sprouting in spring. On the development pollen process,the stage of pollen cell fotmation was long,and the stage of meiosis was shart, on the meio-sis stage,tetraphyte was stable, binary tissue was not stable and could not form the cell wallbetween the two nucleus,it continueel division and formeel for nucleus and formed cell wallon telophase.At the same time of pollon development ovule and embryo sac was formed.Itsdevelopmental stage was closely related with, the floral morphological changes. |
