| Abstract: | 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. |
| Keywords: | Iris blowdowill microsporogenesis male gametophyte |
