高脂马尾松子代与优树性状的典型相关分析

TYPICAL CORRELATION ANALYSIS OF FILIAL GENERATION WITH ELITE TREE OF HIGH GUM YIELD MASSON PINE

采用典型相关分析方法，对高脂马尾松优树林龄，树高、胸径、单株材积的年均生长量，单刀产脂量及其增益，产脂力及其增益８个因子，以及其１３年生子代林的产脂力、树高、胸径、单株材积４个因子分析结果表明：子代产脂力随着优树单刀产脂量、年胸径生长、产脂力和产脂力增益的增加而增加；其中优树单刀产脂量是主要因子，另外，胸径年生长与子代产脂力亦密切相关。以上结论可供今后选优时作参考。

Typical correlation analysis was adopted to analyse the relationship between 8 factors of high gum Masson Pine elite trees and 4 factors of 13 year old filial generation trees. The results shows that gum yield ability of filial generation will increase with the gum yield ability of elite trees and gum yield ability increment, gum output for each cut of elite trees,single breast height diameter growth of elite trees;and the gum output for each cut of elite trees is the main factors.Except for gum yield ability,one years growth of the breast height diameter of elite trees is also closely relation with gum yield ability of filial generation and elite trees.This conclusion can be used for reference when super trees of Masson pine are selected in the future.
