摘要
以10个春兰属品种为试材,对其16个数量性状指标进行了方差分析、相关性分析和聚类分析;对其10个质量性状进行概率分布分析。结果表明:春兰属植物种内的形态性状变异较小,大部分质量性状表现较稳定,数量性状变异较小;种间的形态性状有一定的变异,数量性状上个别表现明显,质量性状表现一致性较高,并且各形态性状间也存在一定的相关性。通过聚类分析表明,16个数量性状可被聚为2类。
With 10 species of genus Cymbidium as materials,16 quantitative traits were analyzed by analysis of variance,correlation analysis and cluster analysis of quality traits;10 quality traits were analgzed by probability distribution analysis.The results showed that the genus of Cymbidium in morphological trait variation was small,most quality traits were relatively stable,quantitative trait variation was small;interspecific morphological characters had a certain variation,quantitative traits on individual performanced significantly,quality traits had high consistency,and the morphological traits also had certain correlation.By cluster analysis,the 16 quantitative traits were clustered into two categories.
