Abstract

In this study, biometrics, physical and microscopic properties of Ficus carica wood were investigated. Three healthy Ficus carica trees in Mazandaran province were selected and felled. Three discs of 5 cm thickness were prepared along the tree (breast height, 1. 9 m height and near the crown). In the transverse direction, 2 × 2 × 2 cm test specimens were sequentially taken from the pith to the bark and examined for physical and biometric properties of the fibers. Then the biometric properties of fibers including fiber length, fiber lumen diameter, fiber diameter and cell wall thickness were measured. Physical properties including basic density, oven dry density, longitudinal shrinkage, radial shrinkage and tangential shrinkage were calculated. Microscopic sections of three surfaces (transverse, tangential and radial) of Ficus carica tree was prepared and the anatomical characteristics of the wood was determined and indexed by IAWA. Anatomical studies near the pith and bark of this wood revealed differences. The most important of these differences are the presence ofTyloses in the vessel lumen near the pith and the absence of this in the near bark, homogeneous rays near the bark and heterogeneous rays in the near pith. The mean tangential vessel diameter near the bark (105 μ m) was larger than near pith (70 μ m) and wood rays were wider near the bark than near the pith. Ficus carica tree was determined to be diffuse porous hardwood species, distinct growth ring, axial parenchyma vasicentric and banded, simple perforation plates. Inter-vessel pits alternate and containing prismatic crystals in parenchyma. The results showed that there were significant differences in both the transverse and longitudinal directions of Ficus carica tree in terms of fiber length, fiber lumen diameter, fiber diameter and cell wall thickness. As the biometric properties of the fibers increased from pith to bark, the mean length, fiber diameter, fiber lumen diameter and cell wall thickness were measured as 1. 05 mm, 30. 47 μ m and 23. 6 μ m and 5. 42 μ m, respectively. The results showed that radial shrinkage, tangential shrinkage, basic density, oven dry density of the pith towards the tree bark had an upward trend and downward from the bottom of the tree towards the crown.
