European beech tending qualitative production crop trees
2015/5/5
The issues related to appropriate management methods of beech stands have been considered as a
crucial topic from the past up to now. Although the positive effect of tending on wood quality in beech...
The proportion of heartwood in conifer (Pinus sylvestris L., Picea abies [L.] H. Karst.) trunks and its influence on trunk wood moisture
pine spruce heartwood moisture content of wood
2015/4/24
As the tree age increases, the formation of heartwood takes place in the central part of the tree. Since there is a large difference in the moisture content between sapwood and heartwood in conifers, ...
Variation of wood density in Turkish hazel (Corylus colurna L.) grown in the Czech Republic
Corylus colurna L wood density variability
2015/4/14
The aim of this study was to investigate the wood density of Turkish hazel (Corylus colurna L.), an introduced species in the Czech Republic. Sample trees coming from a Czech site were tested for basi...
Site classification vs. wood production: a case study based on Silver fir growth dynamics in the Western Carpathians
Western Carpathians site classification production potential Silver fir growth model
2015/3/27
We analysed wood production on an example of Silver fir growth ability within site units defined in the site classification that is currently used in the Western Carpathians. It has arisen as a very i...

Effect of the position in a stem on the length of tracheids in spruce (Picea abies [L.] Karst.) with the occurrence of reaction wood
spruce tracheid length of tracheids compression wood
2015/2/6
The paper was aimed at the determination of variability of tracheid dimensions in spruce wood in relation to the position in a spruce stem. Significant changes in dimensions were found in early-wood a...
Variation of the tree ring micro-hardness demonstrated on spruce wood
wood tree ring micro-hardness penetration strength
2015/2/2
Micro-hardness was used for the study of wood structure (Norway spruce) in the line perpendicular to tree rings (radial surface). The steel indentor 0.25 mm in diameter with flat head was used for thi...
