RESUMO

Objective: To investigate the main morphological characters and interrelationship of Blumea bdsamifera, and to provide the guidance for selection and breeding of Blumea balsamifera. Methods: 19 main morphological characters and their interrelationship were analyzed by using correlation analysis,multiple stepwise regression analysis and factor analysis. Results: Variation coefficients of the morphological characters were big in Blumea balsamifera. Correlation coefficients for morphological characters were significant( P <0. 05 or P < 0. 01). Using factor analysis,19 morphological characters were classified into six principal divisors. Ten morphological characters, including length / wide of leaf,trunk diameter, leaf number of second branch, leaf number of first branch, number of trunk leaf, weight of strong leaf, weight of young leaf,weight of old leaf, number of first branch, leaf number of whole plant, were the main factors which influenced the weight of whole plant leaf. Conclusion: The variation of every morphological character of Blumea balsamifera is abundant in different population, and a certain correlation is existed among morphological characters. The morphological characters, length / wide of leaf, trunk diameter, number of first branch, number and weight of leaf, are the main factors which influenced the weight of whole plant leaf.
