چکیده :

The aim of this study was to determine some of the wood physical properties of 35-year-old Ulmus glabra trees. For this purpose, three normal elm trees were randomly cut down from the Arasbaran-Ardebil site located in northwestern part of Iran. Disks and logs of wood were cut at breast height of stem height. The testing samples were prepared from mature wood to determine physical properties (oven dry density, basic density and volumetric shrinkage). The mean of wood oven-dry density, basic density and volumetric shrinkage were 0.656, 0.575 g cmG3 and 12.39 %, respectively. In addition, the relationships between wood density and volumetric shrinkage were determined by linear analyses. It was found that there were weak correlations between oven-dry density and volumetric shrinkage in Ulmus glabra wood, although these correlations are positive.
