Abstract

The objective of this study was to investigate the biometry of VASCULAR BUNDLES and their roles in the physical and mechanical properties of DATE PALM. To prepare experimental samples, three DATE PALM trees (Phoenix dactylifera) with the average diameter of 47 cm were cut in Ahvaz (Khoozestan Province, Iran). Cubic samples with dimensions of 2 cm (tangential) × 2 cm (radial) × 2 cm (longitudinal) were taken from different heights of a trunk (2, 5 and 7 meter). The biometry of trunk tissue (number, diameter and cross-cut area of single VASCULAR BUNDLES), as well as physical (density) and mechanical properties (vascular bundles tension strength and modulus of elasticity) were studied. The results showed that the calculated total area of VASCULAR BUNDLES was maximum for outer samples (near the bark; 33% of total area) and the values gradually decreased to 27% for inner specimens (around the pith). Moreover, the number of VASCULAR BUNDLES increased from inner to outer parts of trunk. The same trend was also observed from lower to higher heights of a tree; however considering diameter and cross-cut area of a single vascular bundle, no distinct trend was observed. Regarding the mechanical properties of VASCULAR BUNDLES, the results revealed that TENSILE STRENGTH and modulus of elasticity were higher for the specimens close to the pith in comparison with the samples near the bark. Finally, the highest correlation was found between mechanical properties of VASCULAR BUNDLES and their position in the transversal direction of DATE PALM stem.
