A Study of the Effect of Clone on Growth, Biometric and Physical Properties of Populus Deltoides Wood (A Case Study in Shastkolateh Forest in Gorgan)

In this study, the growth, biometric, and physical properties of populus deltoides spp wood from four clones of P.d. 77/51, P.d. 69/55, P.d. 73/51, and P.d. 72/51 located in the educational-research forest of Dr. Bahramnia (the Shastkolateh forest) in the province of Golastan were investigated. For this purpose, three twelve years old normal populus trees were randomly selected and cut down from each clone, and then their growth, biometric, and physical characteristics were measured. Then the data gathered were statistically analyzed. The results showed that clones affected significantly all the parameters, including the tree height, diameter at breast height, stem volume, annual diameter increment, fiber length, cell wall thickness, density and volumetric shrinkage. The results also indicated that the P.d. 77/51 clone of populus deltoides spp, from the growth, biometric, and physical characteristics, was the highest of all compared with the other clones.
