Analysis of Growth Traits Variation of Acacia Melanoxylon R.Br.and Early Selection of Excellent Families
In this paper,47 Acacia melanoxylon R.Br.families in Luoxi Stateowned Forest Farm in Fujian Province were used as ma-terials to analyze the variation of their growth traits.The variation coefficient of each trait were19.38%-87.39%.The coefficient of vari-ation of the number of branches was the largest,and the coefficient of variation of tree height was the smallest.47 inter-family lines were rich in variation.From variance analysis,there were significant differences in sub-branch height,number of branches and trunk straight-ness(p<0.001).It was preliminarily concluded that No.3,No.15,No.22,No.39,No.40 and No.46 had strong adaptability,and No.6,No.9 and No.11 dry type performed best.The research results lay a foundation for the promotion of Acacia melanoxylon R.Br.in Fujian Province.
