Correlation Bnalysis between Leaf Traits and Crown Factors of Osmanthus fragrans,'Pucheng Dan'Based on Stepwise Regression
The correlation between leaf functional traits and stem factors of Osmanthus fragrans,'Pucheng Dan'was analyzed by one-way ANOVA,Pearson correlation analysis,redundancy analysis,and multiple linear regression.The results showed that branch angle and branching rate were two factors that had a strong correlation with leaf functional traits.Branch angle was positively correlated with leaf length,leaf width,leaf thickness,leaf area,leaf circumference,leaf dry weight,and leaf wet weight.Branching rate and the number of branches were negatively correlated with leaf length,leaf width,leaf area,leaf dry weight,and leaf wet weight.The improvement of crown completeness and branch length was beneficial to leaf growth,DBH was negatively correlated with specific leaf area,and other branch fac-tors had little correlation with leaf functional traits.The results indicated that the leaf traits of Osmanthus fragrans,'Pucheng Dan'were affected by the distribution of branches,and the branch angle,the number of branches,and the branching rate were the branch factors strongly correlated with leaves.The research results can provide basis and reference for optimizing the crown structure of Osmanthus fra-grans,'Pucheng Dan'.
