地理位置对人工红松林木材材质变异的影响

对不同地理位置（东北林业大学帽儿山实验林场老山实验站、凉水实验林场和方正林业局）的人工红松林木材材质进行了分析。结果表明：管胞长度和管胞直径的平均值排序为老山＞凉水＞方正、纤维角和壁腔比为方正＞凉水＞老山，长宽比为凉水＞老山＞方正。胞壁率为方正＞老山＞凉水。差异均达到了显著水平；生长速率平均值排序为凉水＞方正＞老山，差异不明显；生长轮宽度和硬度平均值排序为方正＞凉水＞老山，差异显著，利用综合坐标法对人工红松林木材材质进行评定，其优劣顺序为凉水，老山和方正，地理位置不同，木材材质各异，这为人工红林定培育提供了科学依据。

Effect of Different Site on Wood Quality of Pinus koraiensis Plantation

The main wood qualities of Pinus koraiensis plantation in different site (Northeast Forestry University Laoshan and Liangrhui Experimental Forest Farm. Fangzheng Forestry Bureau) were studied. The main results obtained are: to compare the average values of tracheid length and tracheid diameter are Laoshan >Liangshui >Fangzheng. wall-indiameter and fibril angle are Fangzheng > Liaseshui > Laoshan. tracheid length-width ratio is Liangshui >Laoshan>Fangzheng. cell wall percentage is Fangzheng>Laoshan> Liangshui. their differences reach significant level. To compare growth rate is Liangshui > Fangzheng > Laoshan. but their difference does not reach significant level; growth ring density and hardness are Fangzlleng > Liangshui >Laoshan. and their difference reach significant level. By means of comprehensive coordinates, the wood qualities at different site were evaluated. and they are in the order of Liangshui> Laoshan>Fangzheng. In general. the wood qualities are different with different site.
