Summary: Research into the distribution of properties in the radial direction with wood makes it possible to acquire knowledge of their variability, and to determine the characteristic zones within the trunk. As any other living organism a tree undergoes three developmental phases: juvenile, ripeness and old age. The determination of these three phases is possible on the basis of the recorded changes in properties. This research is limited to the study of the differences in the properties of the two phases; the juvenile and ripe phases of the Fir. Some physical properties of the juvenile and ripe wood of a Fir are determined: width of an annual ring, share of the late wood zone, density in raw condition after felling, water content after felling, nominal density and density in the stadnard dry condition. The materijal for research was taken
from the Compartment VI of the Belevine management unit, NPSO Zalesina, managed by the sustainable method. On the basis of the change of the distribution trend in the width of the annual ring, the nominal density and the density in the standard dry condition in the radial direction, the zone ranging from 30th to 40th annual ring was observed, in which juvenile wood transgresses into ripe wood. The juvenile zone infirwood spans over the first 30-40 annual rings from the heart. The annual-ring width, nominal density and density in a standard dry condition of the juvenile wood significantly differ from the same properties of the ripe wood. The width of an annual ring in the juvenile wood is bigger than the width of annual ring in the ripe wood. The nominal density and density in a standard dry condition of the juvenile wood is smaller than the same properties in the zone of the ripe wood.
