Some of Wood Properties of Narrow Leaved Ash (Fraxinus angustifolia Vahl.) From Natural and Plantation Stands in Turkey

Abstract

Ash wood is very important for forest products industry. Because of its fast growing property it was planting for severeal years. Wood quality may change with several factors which one of the important factor is site conditions. The aim of this study was to investigate the anatomical, physical properties and compression strength paralell to grain of natural and planted narrow leaved ash (Fraxinus angustifolia Vahl.) wood at different sites in Turkey. It was shown that there was a significant difference between natural and planted trees and between regions for all wood properties. Planted trees had higher density which had thicker double fiber cell wall, lower earlywood vessel frequency, higher and/or similar ray width, shorter earlywood vessels, lower multiseriate ray high number and length. The maximum oven-dry densities were 0.773 gr.cm-3 in Sinop and 0.719 gr.cm-3 in Adapazarı for planted trees. Higher shrinkage values were observed in denser planted trees. Planted trees exhibited higher compression strength parallel to grain (53.32 N.mm-2 in Adapazarı and 55.32 N.mm-2 in Sinop) than natural trees (51.02 N.mm-2 in Adapazarı and 50.05 N.mm- 2 in Sinop). As a result; planted NLA wood showed better wood properties except shrinkage values.
