| 摘 要： | 大孢子母细胞经过减数分裂，形成功能大孢子，再经３次有丝分裂，发育成雌配子体．在雌配子体形成过程中，子房壁内淀粉的积累有一个动态的变化．小孢子母细胞经过减数分裂，形成小孢子，再经有丝分裂，发育成雄配子体．在雄配子体形成过程中，花药壁内淀粉的积累也有一个动态的变化．大、小孢子母细胞的减数分裂，大、小孢子的产生及雌、雄配子体的形成均具有同步性．

| 关 键 词： | 高粱，雌配子体，雄配子体，淀粉 |

| Abstract: | Megasporocytes turns into megaspore by meiosis,which develops to male gametophyte after three times of mitosis.During the formation of male gametophyte, the starch deposit on the locule wall shows a kind of mobile change. Similarly, microsporocytes turns into microspore by meiosis, which develops to female gametophyte after mitosis.During the formation of female gametophyte, the starch deposit on anther wall shows a kind of mobile change. Meiosis of megasporocytes and microsporocytes occurs simultaneously with produce of megasporegenesis and microsporogenesis, and with formation of male and female gametophyte. |
