JUNIPERUS EXELSA L.: WOOD STRUCTURE AND PHYSICAL PROPERTIES IN IRANO-TORANI REGION

In this research, worked on two juniper trees (Juniperus exelsa L.) in Bakhtiari region as a part of Irano-touranian district. We noted the Sp. Gr. Of wood based on saturated volume 0.52, porosity 64%, volume shrinkage and swelling 10% and 11.3% resp. Anatomical structure and microscopic characteristics had been investigated incidentally. The average length of tracheids 1.3 mm. And the diameter, lumen diameter and thickness of cell wall of tracheids were determined 23.4, 16.3 and 3.5 microns resp. the major pulp indexes are calculated via related formulas.
