Název v původním jazyce

Variability in swelling of spruce (Picea abies /L./ Karst.) wood with the presence of compression wood

Popis výsledku v původním jazyce

Wood is a hygroscopic material which is affected by shape changes. The aim of this study was to analyse the variability with which the wood swelling occurs in the individual anatomic directions. The wood swelling was examined on a sample tree containingcompression wood. With regard to the presence of the compression wood, the sample tree was divided into the following three zones - the compression wood zone (CW), the opposite wood zone (OW), and two side wood zones (SWL and SWR). The results have shownthat the wood containing compression wood swells less at the transverse plane (in the radial and tangential direction). Conversely, the swelling of the compression wood in the longitudinal direction is higher. The same proportion has been established inthe case of the swelling coefficient that grew proportionally to the increasing wood density in all anatomic directions. The proportion of the compression wood manifested its effects in different ways. Transversely (in the radial and tan
