在东北林业大学帽儿山实验林场,选择了26个17年生红松种源实验林作为研究对象,进行了木材材质性状和生长性状的调查。材质性状包括解剖学性状和物理学性状。解剖学性状测试指标包括,管胞长度、管胞直径和管胞壁腔比。物理学性状指标测定了:生长轮宽度、晚材率和生长轮密度。生长性状方面调查了树高和胸径。统计分析结果表明:各项材质性状和生长性状指标在种源间均存在着显著差异,同时证明各项材质性状均受一定的遗传效应控制;红松的生长性状指标在不同种源间也存在着较大的变异,红松的树高和胸径也受遗传效应的控制;但是,多数材质指标表现为一定的以经向为主的地理变异规律,而红松的生长性状指标如树高和胸径均呈现出一定的纬向变异规律,无经向变异规律。图2表5参6。
In the Maoershan Experimental Forest Farm of Northeast Forestry University, 26 17-year-old Pinus koraiensis provenance forests were selected as the research object, and wood quality traits and growth traits were investigated. Material traits include anatomical and physical traits. Anatomical traits test indicators, including tracheid length, tracheid diameter and tracheid wall cavity ratio. Physical properties of the indicators measured: growth wheel width, latewood rate and growth wheel density. Growth traits investigated the height and DBH. The results of statistical analysis showed that there were significant differences among the provenances in all the material and growth traits, and at the same time, it was proved that all the material traits were controlled by some genetic effects. The growth traits of Pinus koraiensis also existed in different provenances However, most of the material indices showed some regular patterns of the geographical variation, while the growth traits of Korean pine as tree height and DBH showed some latitudinal variation, no variation law.
