以采自东北林业大学帽儿山实验林场老山生态站的红松人工林内的试材为例 ,分析和探索了红松人工林木材解剖特征的径向变异模式。结果表明 :①管胞长度、长宽比、胞壁率的径向变异模式为 y =a +blnx ,该模型具有典型的生物学意义。②管胞径、弦向直径和壁厚的径向变异为略呈增加趋势 ,径向直径是早材大于晚材 ,弦向直径是晚材大于早材 ;管胞径、弦向壁厚均为晚材大于早材。③管胞径、弦向壁腔比的径向变化规律不明显 Taking the test materials collected from Pinus koraiensis plantation in Maoershan Experimental Station, Northeast Forestry University as an example, the radial variation patterns of anatomical characteristics of Korean pine plantations were analyzed and explored. The results showed that: ① The radial variation pattern of tracheid length, aspect ratio and cell wall rate was y = a + b1nx. The model has typical biological significance. (2) The radial variations of tracheid diameter, chordwise diameter and wall thickness increased slightly, while the radial diameter was larger for earlywood and latewood for latewood than for earlywood; Latewood is bigger than earlywood. ③ Tracheal diameter, radial to wall-to-wall ratio variation is not obvious
