It is recommended to use the generalized statistical data of physical and mechanical properties of trunk rectilinear and wavy-curly wood of white fir in the conditions of the Ukrainian Carpathians for preparation of assortments of purpose and with decorative texture of wood. The morphological markers of trees with wavy-curved wood include their width and depth, as well as the length of round timber with wavy-relief trunk formations. The formation of the latter is due to the indicators of the macrostructure: the width of the annual ring, the content of early and late wood in the annual ring. The natural differentiation of white fir in the structure of wood should be associated with a sharp change in microclimatic conditions of growth and altitude and environmental factors.
