| 摘 要： | 通过比较培矮 64S、13 5 6S、博A、安农S— 1、明恢 63和G67的开花习性 ,发现培矮 64S具有柱头受粉面积小 ,颖花开闭时间较短 ,柱头生命力下降快 ,柱头外露率较高 ,花期和花时集中 ,与父本同步开花比率较高等特点。并就提高培矮 64S的制种产量进行了讨论

| Abstract: | Pei'ai 64S had smaller stigma dimensions for receiving pollens, shorter glume opening period, lower stigma vitality and higher stigma exsertion percentage, compared with 1356S, Bo A, Annong S-1, Minghui 63 and G67. Its flowering period and hour were found more concentrated and synchronous with male parents. It was also discussed about how to increase the yield in the F 1 seed production of Pei'ai 64S. |
