红松是珍贵的用材树种,选择红松优树主要考虑的经济性状是木材生长速度。而生长速度是遗传数量性状,受环境因子的影响很大,目前采用的选优方法如优势木对比法,固定标准法等均不能排除环境因子的干扰、选出优树的遗传基础是否优良很难判断。树木的形质性状受环境的影响较小,研究红松各形质特征与生长速度之间的相关关系,并根据形质的差异 Korean Pine is a precious species of timber, pine trees choose the main economic character of timber growth rate. However, the growth rate is a genetic quantitative trait, which is greatly affected by environmental factors. Currently, the optimal selection methods such as the dominant wood comparison method and the fixed standard method can not exclude the interference of environmental factors. Difficult to judge. The morphological traits of trees are less affected by the environment. The correlation between the characteristics of the korean pine and the growth rate is studied. According to the difference of the quality
