Annotatsiya
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.
