Also differences in density, initial and final moisture content, moisture gradient, intensity of water evaporation and case-hardening, both before and after drying process, were analysed.The differences in drying rate were noticeable mostly at the beginning of drying process. Slower drying rates, both above and under the fibre saturation point, were represented by compression wood. As expected , the differences in density of compression and opposite wood in oven dry state can be reported. Differences in initial moisture content were not found and the differences in moisture gradient were not considered significant. The negative effect of compression wood on case-hardening was not confirmed. Since the compression wood is the source of difficulties in wood processing, better knowledge of these different characteristics may have positive impact on spruce wood processing.
