Effects of altitude and aspect on wood-water relations in Oriental beech (Fagus orientalis Lipsky.) were studied. Study area divided into five altitude steps and two aspect groups, total of 20 trees were cut off. In order to determine the wood-water relations; volume density value, fiber saturation point, maximum moisture content, and shrinkage and swelling percentages were determined. According to results, with 95% significance level (p<0,05), altitude affects volume density value, shrinkage and swelling percentages, fiber saturation point and maximum moisture content; aspect affects volume density value, tangential and radial shrinkage percentages, volumetric shrinkage percentage, tangential and longitudinal swelling percentages, fiber saturation point and maximum moisture content while it has no effect on longitudinal shrinkage percentage, radial and volumetric swelling percentages. Results demonstrated that northern aspect and first altitude step has the lowest values, thus, this aspect and altitude step making a suitable place for this tree species to be used as solid wood.
