摘要:

本研究对三叶半夏和掌叶半夏进行自交、种间杂交、种内异交,对其生物学特性、授粉和结实情况进行了观测及比较,并分类收获种子,测定其出苗率。研究得出半夏为雌雄同株异花授粉植物。掌叶半夏、三叶半夏的人工杂交、自交均能结实,但种间杂交表现不育;掌叶半夏与三叶半夏种内杂交结实率分别达65%和60%,平均单株结种子分别为37和17粒。掌叶半夏和三叶半夏的自交结实率分别为88.24%和62.5%。

Abstract:

In this paper the study examined the selfing, intraspecific and interspecific crossing between Pinellia ternate and Pinellia pedatisecta Schott.We also tested its pollination, fructification and germination rate in the field’s experiment. The result showed that both of the sexual reproduction were monoecious.Artificial crossing and selfing were fruitive,but intraspecific crossing was sterile. The maturing rate inter Pinellia pedatisecta Schott and inter Pinellia ternate could reach to 65% and 60%, and the mean of the seeds of each plant was 37 and 17 respectively. The selfing maturing rates of Pinellia pedatisecta Schott and Pinellia ternate were 88.24% and 62.5% separately.
