对２０个苹果属植物种类花粉生活力测定、去雄不授粉套袋、不去雄不授粉套袋及人工杂交表明，在多倍体种类中，除海棠花外，均无花粉，属兼性无融合生殖。四倍体种类的无融合生殖能力不低于三倍体种类。在二倍体种类中，除马尔康海棠外，均有花粉和较高生活力，无融合生殖能力，仅珠眉海棠和花叶海棠有较低的座果率和结种率。 Pollen viability of 20 species of apple plants, male sterile pollination bagging, non-pollination non-polluting bagging and artificial hybridization showed that in polyploid types, except for begonia, no pollen, Apomixis. Tetraploid species apomictic reproductive capacity of not less than triploid species. In the diploid species, except Malcolm Begonia, pollen and higher viability, apomictic ability, only the Honeysuckle and begonia have a lower fruitsetting rate and seed rate.
