| 摘 要： | 花粉母细胞间染色质穿壁转移大多发生在减数分裂Ⅰ的前期联会时期，偶尔也有在其他时期发生的。作者在麦类远缘杂种的减数分裂过程中发现，在减数分裂Ⅰ的前期和小孢子时期均存在核穿壁的现象，并对各种状态下的穿壁现象进行了详细的观察研究。

| Abstract: | Cytomixis in pollen mother cells usually occured at prophase of meiosis I, but this phenomenon was observed at other stages occasionally. In the course of present investigation in interspecific hybrid of Tritical crops, cytomixis mas observed at microspore stage, the present investigation deals with detailed analysis of this phenomenon at different conditions. |
