| 摘 要： | 采用去雄、套袋、人工授粉方法对7种枇杷属植物及2种枇杷近缘属植物共14份材料配置的91个种间、21个属间共112个杂交组合进行研究，结果发现：91个种间杂交组合中有28个坐果率为零，即杂交不亲和，约占30%；杂交组合大多为部分亲和，仅少数为完全亲和。枇杷属与其近缘属植物（石斑木、石楠）的正交基本不亲和，反交有5个组合能结果，但杂种胚中途败育，需要进行胚挽救。不同的种类作为父本或母本时，坐果率相差较大，以大渡河枇杷，栎叶枇杷、野生普通枇杷和‘解放钟’作母本，平均坐果率高达36.2% ~ 58.2%；而以台湾枇杷及其两个变型和椭圆枇杷作母本，平均坐果率仅为2.9% ~ 16.3%，作父本时，平均坐果率较高，达22.4% ~ 43.1%。花粉管生长的荧光观察显示，台湾枇杷恒春变型作母本与栎叶枇杷杂交为孢子体不亲和。

| Abstract: | The cross-compatibility experiments of 91 inter-specific combinations and 21 inter-generic combinations were carried out among 7 Eriobotrya plants and 2 related genera（Raphiolepis indica Lindl. and Photinia serrulata Lindl.）by emasculation，bagging，and artificial pollination. The results showed 28 in 91 inter-specific combinations set no fruit，which means nearly 30% was incompatible. In the rest combinations，most of them were partial cross-compatibility，a few of them were complete cross- compatibility. The cross between Eriobotrya and its related genera plants（R. indica Lindl. and P. serrulata Lindl.）were incompatibility. The back cross of them have 5 compatible combinations could set fruits，which incompatibility developed. The F1 plants could obtain only after embryo rescue. Various species as male or female got difference fruit setting ratio，E. prinoides Rehd. & Wils.，common loquat（E. japonica）and Eriobotrya × daduheensis H. Z. Zhang ex W. B. Liao，Q. Fan et al. as female plant got 36.2%–58.2% average fruit-setting ratio；while E. deflexa Nakai and its two forms，and E. elliptica Lindl. as female plant just got 2.9%–16.3% average fruit-setting ratio，but got as high as 22.4%–43.1% average fruit-setting ratio when they used as male plant. Fluorescent observation of pollen tube growth showed that no fruit-setting from E. deflexa f. koshunensis Nakai × E. prinoides Rehd. & Wils. might be derived from the sporophyte incompatibility. |
