Density of juvenile and mature wood of selected coniferous species

Popis výsledku v původním jazyce

The objective of the research was to determine the density of juvenile (JW) and mature wood (MW) of selected coniferous species growing in the Czech Republic. The research included the wood of Norway Spruce (Picea abies (L.) Karst.), Scots Pine (Pinus sylvestris L.) and European Larch (Larix decidua Mill.). The juvenile wood density close to the pith was 410 kg/m3 for the spruce, 391 kg/m3 for the pine and 573 kg/m3 for the larch with 12 % water content. The mature wood in the peripheral parts was of ahigher density for all the species -- spruce 516 kg/m3, pine 552 kg/m3 and larch 652 kg/m3. The highest difference, the difference of 161 kg/m3 between juvenile and mature wood, was found out in the Scots Pine. The high difference in the wood density ofpine is caused by a considerable difference in the mean ring width of its juvenile and mature wood. Further, it was proved that with the increasing ring width the wood density decreases, and with the increasing proportion of latewood the
