| 摘 要： | 用石蜡切片法，对普通小麦（Ｔｒｉｔｉｃｕｍ ａｅｓｔｉｖｕｍ Ｌ．）异源２ 号、中国春与球茎大麦（Ｈｏｒｄｅｕｍ ｂｕｌｂｏｓｕｍ Ｌ．）远缘杂交受精过程和早期胚胎发育进行了比较观察．实验表明，仅具１对Ｋｒ基因的异源２ 号和具３ 对Ｋｒ基因的中国春与球茎大麦杂交，其受精和胚胎发育存在着明显的差异．为小麦与球茎大麦远缘杂交提供了细胞胚胎学证据．

| Abstract: | Observations were made on the fertilization and early embryo development in intergeneric crosses of Triticum aestivum <.cv.Yiyuan 2 and T.aestivum L.cv.Chinese Spring to H.bulbosumL.Evident defference presented in the fertilization and embryo formation of this study perhaps result from the effects of Kr genes in Yiyuan 2 and Chinese Spring.Cytoembryological evidence was given to demonstrate the high frequencies of fertilization and embryo formation in crosses between wheat and H.bulbosum. |
