Abstract

The physical and anatomical properties of FAGUS ORIENTALIS (wood and bark) and their variations in three heights and radial directon in the trunk of tree were analysed in this study. Three FAGUS ORIENTALIS trees were cut down at "Shenrood forest" in west of Lahijan (Siahkal). From each tree, 3 DISKs from the bottom, middle and top of the tree trunk were selected. The Specimens were prepared from these DISKs to measure the main properties, such as MOISTURE CONTENT, DRY SPECIFIC GRAVITY, total shrinkage and FIBER LENGTH, FIBER EFFICIENCY, L/D RATIO.Then, data from 3 heights and RADIAL DIRECTION in the trunk were statistically analysed. The results show that there was little change in the MOISTURE CONTENT of wood RADIAL DIRECTION, but it increased from bottom to top of the tree when the three heights were compared. The specific gravity and total VOLUMETRIC SHRINKAGE of wood in RADIAL DIRECTION decreased from pith to bark and from bottom to top of the tree whereas there were little change in FIBER LENGTH, FIBER EFFICIENCY and L/D RATIO of wood. There were also little change in MOISTURE CONTENT, DRY SPECIFIC GRAVITY, volumertric shrinkage and FIBER LENGTH of bark in LONGITUDINAL DIRECTION of tree trunk, but FIBER EFFICIENCY of the bark in the middle part and its L/D RATIOn in the lower part of tree trunk were higher than other parts.
