The influence of tree’s age on the physical properties and fiber length of wood species of Eucalyptus Camaldulensis wood in the Zabol region

The easy plantation, growth rate and other advantages caused Eucalyptus Camaldulensis to be spread to different parts of the world and to be planted in many countries. In order to examine the properties of Eucalyptus Camaldulensis, ten healthy trees of two age groups of 14 and 20 years old, were sampled from Agriculture Research Center of Zabol city and their physical properties and fiber length were measured using the standard ASTM-D143 and Franklin method respectively. The analysis of variance (ANOVA) indicated that the trees's age and radial axis had significantly effect on the oven-dry density, basic density, volumetric shrinkage, volumetric swelling and fiber length. The increase of the trees's age would increase the mentioned properties of eucalyptus wood. The values of wood density, volumetric shrinkage and volumetric swelling along radial axis from the pith to the bark were decreased while fiber length was increased.
