摘　　要：以昆明地区自然生长的3个厚皮香植株居群为对象,从花部解剖结构,雄性花与两性花的异株状况,花粉与胚珠比特征,花粉形态及其散布特性等方面,对居群中厚皮香植物的花部特征及传粉生殖特性进行了野外观察及室内的分析研究。其研究结果表明:厚皮香为异花授粉植物,存在风媒与虫媒传粉机制,虫媒传粉显示了其独特的“蜂鸣植物”特性。Taking three populations of Ternstroemia gymnnanthera in Kunming district as the study targets, field observation and lab analysis on flower characteristics and pollination characters were conducted particularly on anatomical structure of flower, male flower, bisexual flower, pollen/ovule, morphological and distribution of pollen. The results showed that Ternstroemia gymnnanthera was cross-pollinated plant, the species could be pollinated by wind and insect.
