昆明地区不同居群厚皮香植物群落特征及繁殖特性的初步研究

对昆明地区 3个居群厚皮香的植物群落特征 ,该种植物的花期物侯以及花、叶器官在数量上的变异等繁殖特性进行了观察研究。发现厚皮香的生存适应能力较强 ,以半阴的林缘环境生长最好 ,阳坡生长次之 ;在阴生环境下不能正常开花结实 ;该植物存在雄性花与两性花异株情况 ,两性花比雄性花的花瓣要大 ,且变异小 ;花期物候显示 ,大小孢子发育基本一致 ,同一枝条与不同枝条上的所有花芽的开花与结果期几乎一致 ,而不同植株上的花芽开花与结果期存在一定时间差异。

Community characteristics and Reproductive Characters of Ternstroemia gymnanthera in Kunming of Yunnan Province

The community character, a series of reproductive characters such as phenophase of flowering, variation of vegetative and productive organs were studied. The results show that T.gymnanthera has promising adaptability to Kunming, the performance by the side of Pinus armandii is the most desirable, the growth at the exposed place is also satisfied, and has no sexual reproductivity in Keteleeria evelyniana forests. T.gymnanthera is andriodioecy, bisexual flower has bigger petal than monosexual flower. The microsporegensis, megasporegensis, the flowering time and fruiting time are at the same time among the same and different shoots, but there are some differences among the different tree individuals.
