红松人工林木材解剖特征与气象因子的关系

The Relationships between Anatomical Characteristics of Wood and Meteorological Factors of Plantation Forest of Pinus koraiensis

主要研究了红松人工林木材解剖特征与气象因子的关系。结果表明：管胞长度随温度增加而增长，相关程度达显著水平；管胞径向直径与降雨量、相对湿度、日照呈显著正相关．与温度呈显著负相关；管胞径与弦向壁厚和温度与相对湿度呈显著正相关；胞壁率与温度呈正相关；纤丝角与日照是正相关，与温度呈负相关。得出气象因子对木材解剖特征有显著影响的结论，这为红松林的定向培育提供科学依据。

The relationships between anatomical characteristics of wood and meteorological factors of plantation forest of Pinus koraiensis were studied. The results show that tracheid length is significantly positive correlated to temperature. There are significantly positive correlations between tracheid radial diameter and rainfall. relative humidity and sunshine. negative correlations between wall-indiameter ratio and temperature. There are positive correlations between fibril angle and sunshine. negative correlations between fibril angle and temperature. There are significant effects of meteorological factors on anatomical characteristics of wood. The results can provide the theoretical base of the man-made forest intensive management.
