Title

COMPARATIVE WOOD ANATOMY OF STEM AND ROOT OF CALLIGONUM COMOSUM GROWN IN THE DESERTS OF IRAN AND THE TECHNICAL PROPERTIES PARTICLEBOARD PRODUCED FROM ITS WOOD

Pages

  538-551

Abstract

 Understanding the wood technological features depends on anatomical characteristics of the wood itself. Unfortunately, researchers in Iran have not focused on this issue recently. There are many trees and shrubs in the desert areas of Dasht-e Kavir and Dasht-e Lut whic woody anatomical features are not yet studied. We studied one of these species, Calligonum comosum (Polygonaceae). Three mature shrubs were selected and small cubic samples of woody stem and ROOT were taken. Micro-sections were obtained with microtome and after dying with Astra-blue and Safranin the sections were mounted in Canada balsa and the anatomical features were investigated. The results showed that differences between ROOTs and stems exist. The distinct growth rings in the stems and indistinct rings in the ROOTs, the presence of gums in the stems and absence in the ROOTs, and lower ray width of the stems compared to the ROOTs were observed and inherent characteristics that have been reported by other researchers were determined. The most important difference between Calligonum comosum’s ROOTs and stems is parenchyma-like fibers in the thin-walled ROOTs which cannot be distinguished from axial parenchyma. The ground tissue of woody ROOTs is parenchymatous cells full of STARCHes, which probably can be related to the drought situation of deserts. The bark of Calligonum comosum contains priderm and sclereid cells which make the bark stiff and hard. Also the properties of PARTICLEBOARD produced from Calligonum comosum’s wood showed that boards has at least technical characteristics of European Standard EN 312 and hence the cultivation of this species for stoping of erosion of soil is advised and it is suitable species for desertification and its wood can be used to produce wood based panel.
