Canonical Correlation Analysis of Growth Traits between Superior Trees and Progenies of Pinus tabulaeformis
摘要
Abstract
With 29 superior tree materials of Pinus tabulaeformis and their progeny testing materials as the research object,the selection factors of superior trees of Pinus tabulaeformis,including the per-centage of tree height,DBH,and volume growth that are greater than the dominant contrast trees,and the correlation between the annual growth of superior trees and the growth factors of the progeny testing forests in Luonan and Huangling were studied.The genetic variation analysis of the growth traits of the progeny forest is also conducted.The results showed that supeiror tree selection factors were not closely correlated with growth factors of progeny in Lounan and volume of progeny in Huan-gling.There were highly correlated with the height and DBH of progeny in Huangling.The height and the volume of superior trees are highly correlated with the volume and the DBH of progeny.Ca-nonical correlation analysis indicated that the growth percentage over the control tree has no signifi-cant influence on growth factors of progeny,and per year growth of height of superior trees has sig-nificant influence on the DBH and the volume of progeny.According to the results of the comparative method of selecting 5 dominant trees,more than 80%of the families are greater than the control,in-dicating that the selection effect is good.关键词
