Abstract

 This study investigated the effects of POPULUS DELTOIDS spp trees age on biometrical, physical and chemical properties of wood. For this purpose, three normal Populus trees were randomly cut down in different ages with 4, 8, 12, 16 and 20, 12 years old from Shastkolateh Experimental Forest located in Gorgan. Anatomical, physical and chemical properties of each tree were measured. Then data were statistically analyzed. The results indicated that the effects of different ages of POPULUS DELTOIDS spp trees on fiber dimension (fiber length, fiber diameter and cell wall thickness), wood PHYSICAL PROPERTIES (dry density, critical density and volumetric shrinkage) and CHEMICAL COMPONENTS (cellulose, lignin, extractives materials in alchoal-aceton, hot water, sodium hydroxide soluble extractives and ash) have significant difference in 95% confident levels. Also, the results revealed that there are no significance differences in ANATOMICAL CHARACTERISTICS, PHYSICAL PROPERTIES and CHEMICAL COMPONENTS of POPULUS DELTOIDS spp trees after 12 years old because in this age the period of juvenile wood of POPULUS DELTOIDS spp trees is finished. Therefore, based on fundamental properties of wood, the best cutting age of POPULUS DELTOIDS spp trees (77/51 clone) from Shastkolateh zone in GOLESTAN PROVINCE is 12 years old.
