摘　　要：选取中亚鸢尾为试材,通过石蜡切片的方法,对其小孢子发生和雄配子体发育进行了观察研究。中亚鸢尾花药壁发育方式为双子叶型,绒毡层为腺质;小孢子母细胞减数分裂时胞质分裂即有连续型,也有同时型。小孢子为四面体型和左右对称型,成熟花粉粒为二细胞。The investigation of microsporogenesis and the formation of male gametophyte in Iris blowdowill are made in this article. The main results show that: the development of anther wall belongs to the dicotyledonous type. The tapetum is glandular tapetum. Cytokinesis of microsporpcyte meiotic division are successive type and simultaneous type, the microspore tetrads atr trtrahedral type snd isobilatrtal type, respectively. Mature pollen grain is of the 2-celled type.
