A Study of Anatomical Characteristics, Fiber Biometry and Some Other Physical Properties of One of the Most Important Clones of Poplar (Populus deltoides 77.51) in Gilan

Increase in wood consumption has been accompanied by population increase. The importance of cultivated fast growing species and clones of poplar is indicated by the fact that many have been imported to Iran and cultivated in Gilan through recent decades. Among them some clones like Populus deltoides 77.51 are of better compatibility and higher wood yield. Therefore, it was paid more attention to by farmers as well as poplar culturists. Best wood utilization is found to be in close relationship with recognizing the species, anatomical charactrestics, biometr as well as physical properties. Specific gravity in this clone is 0.388 gr/cm^3 with average length and diameter of fiber of 946.95 and 25.4 microns respectively. Anatomical charactrestics: wood is semi-ring porous, homocellular, vessels are single or jointed together in groups of double, triple or tetra bands.
