中国兰花品种数量分类初探

运用计算机对中国兰花３７个品种和３７个形态特征性状进行了数量分类研究．Ｒ分析揭示了性状之间的相关性，初步得出了中国兰花种级分类的特征性状和品种分类特征性状，同时证明了本研究所采用的特征性状的独立性和稳定性．Ｑ分析得出了中国兰花种级分类界线和类型分级界线，将３７个兰花品种大致分为：兜瓣型、竹叶瓣型、多花型、素心瓣型和奇瓣型．最后在Ｒ分析和Ｑ分析的基础上讨论了建立“兰花品种分类管理信息系统”的一些初步设想．通过分析，作者认为建立这一套系统是必要的，也是可能的．

The Numerical Taxonomy of Chinese Cymbidium

In this paper, 37 varieties and 37 characters of Chinese cymbidium are studied by means of numerical taxonomic methods. The R cluster reveals relationships among characters, at the same time, the authors preliminarily derive some characters for species and varieties classification. According to the Q cluster analysis, the 37 varieties are classified as Cymbidium goeringii, Cymbidium sinense and Cymbidium faberi. Furthermore,the authors divide these varieties into five types,i.e. pocket like petal, bamboo leaf like petal, multi flower, unspotted petal and abnormal petal type. Based on the R cluster and Q cluster analyses,the authors discuss the necessity and feasibility on the establishment of Management Information System of Chinese Cymbidium Classification.
