Study on intraspecific variation of Vitex rotundifolia growed in China with numerical taxonomy method
摘要
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.关键词
