Abstract

In this study POPULUS ALBA native clone and Populus euramericana 476 clone trees from Gorgan University educative forest were used. Some applied anatomical and physical properties of these species were determined. Results showed that the juvenility age for both species is approximately 10 years .In both species with increase of annual rings upto tenth ring the FIBER LENGTH increase intensively. After tenth ring in P. alba this trend keep on slowly but in P. euramericana the average length of fiber decreased as increase of annual rings. With regard to the annual growth the JUVENILE WOOD percentage in the P. alba and euramericana species were 46.8% and 73.8%, respectively. Basic density of breast height in P. alba and P. euramericana species were 0.329 and 0.318 g/cm3 respectively, that increases from pith to bark. Furthermore there is significant difference between density of JUVENILE WOOD and MATURE WOOD in both species. The pattern of shrinkage in studied species had decreasing procedure from pith to bark.
