赣南十六个脐橙品种叶数量性状分析
|
摘要
以16个赣南脐橙种植品种为试材,测定了16个脐橙品种的叶长、叶宽、复叶长和复叶宽4项叶片性状特征,通过数量分类的方法进行主成分分析和聚类分析,研究了赣南脐橙叶片性状的相互关系。结果表明:主成分分析中前2项特征根累计贡献率达94.05%,第1主成分为叶宽因子,第2主成分为复叶因子;系统聚类把脐橙分为4个品种群,即小叶品种群、中叶品种群、长叶品种群、复叶品种群;该试验初步为脐橙品种的系统整理和科学划分提供了参考。
Taking 16naval orange varieties which planted in Gannan as materials,through quantitative classification methods of principal component analysis and cluster analysis,the leaf length,leaf width,compound-leaf length and compound-leaf width of 16naval orange were studied,in order to make known of the relationship of naval orange's leaf traits.The results showed that,the principal component analysis in the first two characteristic roots cumulative contribution rate was 94.05%,the first principal component was leaf width factor and the second principal component was compound-leaf factor.System clustering of 16navel orange's leaf traits showed that the oranges was divided into four species groups,i.e.small leaf group,middle leaf group,long leaf group and compound-leaf group,the experiment was to provide a reference for preliminary scientific division and cultivars system arrangement for navel orange.
