Growth Traits Analysis and Selective Factors determination of Seedling of Pinus tabulaeformis
Abstract：To determine the selection factors of seedling of Pinus tabulaeformis,the 19 traits of that were studied through the correlation and principal component analysis.The results showed that the range of variation coefficient is 28%～91.6%.Ground diameter,seedling height,crown width and root range were very significantly correlated with total fresh weight（r=0.88,0.83,0.82 and0.73,respectively）.The principal component analysis showed that 19 characters were integrated into 4 principal components and their additive contributing rate reached 75.14%.Best of all,the four factors of total fresh weight,ground diameter,crown width and seedling height could be used as the main selection factors of three-year-old Pinus tabulaeformis seedlings.
