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。
Using canonical correlation analysis method, this paper analyzed the relationship between age, tree height, DBH, annual average growth of single plant volume, fat yield and its gain, fat yield and its gain of Pinus massoniana, The results of four factors analysis of fattening, tree height, diameter at breast height and single plant volume of annual progeny showed that the fat yield of offspring increased with the single-knife yield, annual DBH, fat yield and fat gain The increase of single-knife production was the main factor. In addition, the annual growth of DBH was closely related to the fat production of offspring. The above conclusions can be used as reference in the future when selecting the best.
