摘要:
分析了中国分布单叶蔓荆的种内变异。每个居群随机采取5个以上的完整植株,以16个居群单叶蔓荆作为分类运算单位(operational taxonomic unti,OTU),选取11个有变异的形态学性状和3个品质性状。形态性状以各植株的平均值作为OTUs的原始数据,形成16×14的原始数据矩阵,对矩阵进行聚类分析。根据Q分析树系图3,由结合线水平(类间距离等于10)可将16个居群分为三组,Ⅰ(12,15,14,7,16,2,1,3),Ⅱ(8,13,11),Ⅲ(4,5,9,10,6)。国产单叶蔓荆居群分为三型,即低纬度型、混杂型Ⅰ和混杂型Ⅱ。部分显示居群种内变异呈现出与纬度的相关性,而部分居群变异较为复杂,可能受包括纬度在内的多种因素的复杂影响。
Abstract:
The intraspecific variation of different populations of V.rotundifolia was investigated with numerical taxonomy methods. More than five whole strains per population were selected randomly,then 13 varied morphological characters and 3 qualitative characters was included,and 16 populations were treated as operational taxonomic unit. Average value of morphological characters of all strains per population was treated as primary data for operational taxonomic unit to establish the primary 16×14 matrix which was further processed with hierarchical clustering method. The results showed that all populations could be divided into 3 groups, including Ⅰ(12,15,14,7,16,2,1,3),Ⅱ(8,13,11),Ⅲ(4,5,9,10,6). All populations of V.rotundifolia could be classified into 3 types by results of hierarchical clustering analysis:type Ⅰ distributed in low latitude regeons,complexing typeⅠ,complexing typeⅡ. The intraspec variation of some populations was highly correlated with latitude variation,and the other with complexing variation might be influenced by various factors including latituderelated ones.
