The paper presents the results of analysis of anisotropy of transverse swelling of the Serbian spruce wood. The analysis included six trees that come from plantations and nine trees from natural stands of Serbian spruce, and a total of 3098 samples were tested. The results show a change in transversal anisotropy at the height of the tree, as well as its change in radius. The dependence of this property on the growth rings width, the participation of late wood and the density of wood was determined by regression analysis.
