| 摘 要： | 利用常规石蜡切片技术，对阿月浑子的大小孢子发生及雌雄配子体发育过程进行观察，探讨其发育过程中是否存在生殖障碍。结果表明：（1）花药壁由外向内分别为表皮、药室内壁、中层和绒毡层。绒毡层类型为腺质绒毡层。（2）小孢子母细胞减数分裂过程中的胞质分裂方式为同时型，小孢子四分体排列方式为左右对称型。（3）成熟花粉粒为2–细胞型，具有3个萌发孔。（4）子房具有1个胚珠，基生胎座，双珠被，厚珠心，倒生型；胚囊发育类型为蓼型。（5）雌配子体发育过程存在部分胚珠退化现象。

| Abstract: | The microsporogenesis,megasporogenesis,and development of the male and female gametophytes of pistachio were observed by paraffin section technique to test whether there is any obstacle of reproduction in the process of sexual reproduction.The results showed:(1)The wall of anther consists of epidermis,endothecium,middle layers and tapetum from out to inside,tapetum cell is of glandular tapetum.(2)Cytokinesis during meiosis of the microspore mother cell was simultaneous type,and tetrads were isobilateral(.3)... |
