Identification of Iranian Hardwood Timbers and Indigenous Softwoods via Cross Section Macroscopic Characteristics

In this research the identification method of Iranian hardwood timbers and indigenous softwoods via cross section characteristic and with use of lens have been studied. For this aim at the first, cross section of samples have been surfaced with sharp razor and then with different magnification and have been photographed via loupe. Results showed that apart of colour and texture of species, the presence or lack of resin canal is main parametr of softwoods genus identification. Vessel arrangement, tyloses in early wood vessels and distinct and indistinct of rays are most important identification factor in ring-porous hardwoods identification. But presence or lack of banded tangential parenchyma, distinct or indistinct of rays and also vessels arrangements play important role in identification of diffuse-porous hardwoods identification.
