摘　　要：以楚雄及腾冲33株野生和半野生的腾冲红花油茶作为观察研究对象,对其花器官数量性状进行观察,分析腾冲红花油茶的花器官数量特征及其变异特点。结果表明:腾冲红花油茶花器官数量均有变异,苞片和萼片5～13片,花瓣5～12片,雄蕊66～174条,花柱2～5条,子房室2～5室,每室胚珠1～10粒,每果胚珠6～23粒,变异系数为12. 46%～26. 37%。其中,子房室数量的变异系数最小,而每室胚珠数量的变异系数最大。腾冲红花油茶花器官数量差异主要发生在株间,花瓣和花柱的数量差异主要发生在居群间,而且差异均为极显著。The wild and semi-wild Camellia reticulata from Chuxiong and Tengchong was used as the observation object,and the quantitative characteristics of flower organs were observed.The quantitative characteristics and variation characteristics of flower organs of C.reticulata were analyzed.The results show that the number of C.reticulata organs varies.5-13 bracteoles and sepals,5-12 petals,66-174 stamens,2-5 stylets,2-5 stylets lo-cules,1-10 ovules per locule,6-23 ovules per fruit,the coefficient of variation is 12.46%-26.37%.Among them,the coefficient of variation of the number of locules is the smallest,and the coefficient of variation of the number of ovules per locule is the largest.The differences in the number of organs of C.reticulata mainly occur between the plants.The differences in the number of petals and stylets mainly occur among the populations,and the differences are extremely significant.
