In this research study, the biometric properties of fibers and microscopy of fraxinus wood were investigated. For this purpose, a perfectly healthy stem of the fraxinus tree native to Chamestan area was selected and one disc of 5 cm thickness was prepared at breast height. In transverse direction, the test specimens were cut 2 × 2 cm to 3 cm from the pith to the bark sequentially and examined. Then, the biometric properties of the fibers including fiber length, fiber lumen diameter, cell wall thickness and fiber diameter were measured.
The results showed that all the dimensional properties of the fibers from the brain to the skin were increasing. In order to microscopically study fraxinus tree wood, microscopic sections of three transverse, tangential and radial surfaces of wood close to the bark of the fraxinus tree were prepared and evaluated by a light microscope. Results of the anatomical study indicated that the fraxinus tree is a ring porous hardwood species with distinct growth, simple perforation plates and scalariform, alternate intervessel pits and without tyloses.
