本文用去雄套袋，不去雄套袋和去雄授粉套袋法，研究了湖北海棠等７个苹果属种或生物型的无融合生殖特性。结果表明，毛山定子Ｍａｌｕｓｍａｌｕｓｍａｎｄｓｈｕｒｉｃａｋｏｍｏｒｏｖ．株眉海棠Ｍ．ｚｕｍｉＲｅｈｄ不具无融合生殖特性。湖北海堂Ｍ．ｈｕｈｅｈｅｎｓｉｓ，Ｒｅｈｄ．不同生物型间无融合生殖特性差异很大，其特性与其倍性有明显相关性。
In this paper, we studied the apomictic and biotype apomictic characteristics of 7 apple genus, such as Begonia cambogia, without removing male and female pollinators. The results show that Mao Shan stator Malusmalusmandshuricakomorov. Zhu Mei Begonia M. zumiRehd does not have apomixis. Hubei sea hall M. huhehensis, Rehd. Differences in apomictic reproductive traits between different biological types are significant, and their characteristics are significantly related to their ploidy.
