Abstract

The purpose of this study was to compare the CHEMICAL COMPOSITIONS and biometric features of stem and cone fibers (length, diameter, and wall thickness) and the derived coefficients of loblolly pine (Pinus taeda) in Astara district, Gilan province. Discs from stem and cone were randomly taken and the CHEMICAL COMPOSITIONS and biometric features were measured employing the TAPPI standard test methods and Franklin macerating technique, respectively. The biometric coefficients were estimated as well. Statistical analyses of the results indicated that the average cellulose content in stem and the cone were 54.83% and 27.57%, respectively. Lignin was estimated to be 32.57% in the stem and 34% in the cone. Furthermore, extractives soluble in ethanol, acetone and water from stem wood were measured as 92%, 1.97% and 7.04% respectively. The relevant values for PINE CONE were 1%, 2.45% and 7.28%, respectively. According to the results of statistical analysis, there was significant difference (a=5%) between the results measured from cones and the stem except for the SLENDERNESS RATIO. Regarding the length, diameter, lumen diameter and flexibility factor, the P. taeda stem possesses a higher value compared with cone and the RUNKEL RATIO was higher in cones compared to stem.
