对福建闽候南屿国有林场引种３１个种源的火炬松木材的管胞形态特征变异情况进行了试验分析、结果表明：①种源间管胞特征值中仅早晚材管胞长度及其加权值、腔径比差异显著。②管胞形态特征值种源间个体变异大于种源间的变异。③基本密度与单位面积细胞数目、晚材率、壁厚、长宽比、壁腔比呈极显著正相关，与管胞宽度、腔径比呈极显著负相关，与管胞长度的正相关不显著。④年轮宽度与管胞长度、长宽比、基本密度呈极显著负相关，与晚材率呈显著负相关，与单位细胞数目、壁厚呈负相关，与管胞宽度呈显著正相关，与腔径比正相关不显著。⑤纬度与管胞长度、宽度、直径、腔径比里负相关，与管胞壁厚、壁腔比呈正相关：经度与管胞长度、宽度、直径、腔径比呈正相关、与管胞壁厚、壁腔比呈负相关。
The variation of tracheid morphological traits of the Pinus taeda wood introduced from 31 provenances in the state-owned forest farm of Minhou South Island in Fujian Province was tested and analyzed. The results showed that: (1) Only the tracheid length and its weight Value, cavity diameter ratio difference is significant. ② tracheid morphological eigenvalue individual variation greater than the source of variation between provenances. ③ The basic density and the number of cells per unit area, latewood rate, wall thickness, aspect ratio, wall cavity ratio was extremely significant positive correlation with tracheid width, diameter ratio was significantly negatively correlated with the tracheid length Not obvious. (4) The annual ring width was significantly negatively correlated with tracheid length, aspect ratio and basic density, negatively correlated with latewood rate, negatively correlated with unit cell number and wall thickness, positively correlated with tracheid width, Positive correlation with cavity diameter was not significant. (5) The latitude is negatively correlated with the length, width, diameter and lumen diameter of tube trachea, and positively correlated with the wall thickness and wall cavity ratio of tube trachea: the longitude has a positive correlation with the length, width, diameter, Thick, wall cavity ratio was negatively correlated.
