| 摘要: |
| 采用延迟授粉和胚胎学显微观察的方法，研究了黑麦和六倍体小黑麦花粉诱导小麦孤雌生殖的假受精特性。结果表明：①用六倍体小黑麦花粉授粉，精子进入胚囊的频率高于黑麦花粉；②受粉后2h，一个精核已进入卵细胞质中，极少数精核能够刺激卵细胞单性分裂形成胚；③极核正常受精后形成胚乳。 |

| Pseudogamy Property of Wheat Parthenogenes is Induced by Distant Hybridization |
|
|
| Abstract: |
| The study on pseudogamy property of wheat parthenogenesis is conducted by means of delaying pollination and observing embryo sac with microscope.The results indicate that: ①the frequency of sperms with hexaploid triticales entering wheat embryo sac is higher than that of rye's;② two hours after pollination,one sperm enters egg cell cytoplasm and egg cell parthenedivision can be stimulated by few sperms; and ③ one sperm can be fused with polar neclei to form endosperm. |
