physical and biometry properties of evonymus latifolia wood (case study in chamestan-nour)

The present study carried to investigate physical and biometry properties of Evonymus latifolia wood. For this purpose three normal of trees were selected from Chamestan-Nour city of Mazandaran province. Three log-5 cm thicknesses were taken at 1.30, 3 and 5 meter from each tree. Three samples position were prepared along radial position from the pith to the bark. Then physical properties (basic density and volumetric shrinkage), biometry properties (fiber length, fiber diameter and cell wall thickness) and morphological properties (slenderness, Runkel, flexibility, rigidity coefficients and Luce's shape) were determined by SPSS software. Analysis of variance (ANOVA) indicated that the effect of longitudinal and radial postions had significant differences on the volumetric shrinkage, fiber length, fiber diameter and cell wall thickness. There is a significant difference among samples of radial position in basic density. The physical and fiber diemnsions along vertical direction from bottom to upward of trees were decreased. With increasing of cambial age, the amount of basic density, volumetric shrinkage, fiber length, fiber diameter and cell wall thickness were increased. The averge of basic density was 0.558 g cm-3, the volumetric shrinkage 18.21%, the fiber length was 1.316 mm, the fiber diameter was 25.02µm, the cell wall thickness was 7.24 µm, the slenderness coefficient was 53.19, the flexibility coefficient was 42.06%, the runkel coefficient was 1.41, the rigidity coefficient was 28.96% and the luce's shape pe was 0.698.
