The basic physical properties of spruce wood from plantations in the surroundings of Banja Luka were researched. The dependence of growth ring diameter and wood density, density, volume porosity, shrinkage, fibre saturation point and absorption of moisture were analysed on three trees average age ...

In this study the effect of high temperature on mechanical properties, dimensional stability and color of spruce was investigated. Wood specimens conditioned at different relative humidities (50, 65, 80 and 95%) were subjected to heat treatment at 200°C for 2, 4, 8, 10 and 24 h and at...
Tabulates the mean and weighted mean values (from large populations) of late-wood %, oven-dry density, compression strength and bending strength of Picea abies from the Bayrischer Wald, obtained from two test stems. Previous results are confirmed, and some relationships expressed in the form of...
Decreasing trend and fluctuations in the mean ring density of Norway spruce through the twentieth century * Studies on wood density variations are necessary for estimating the forest carbon pool. Further, they can help predict the technological properties of wo......

The discussions on growth-rate and wood properties have focused on three key concepts. Firstly, increase in the proportion of juvenile wood in structural products. This has been attributed to an interaction of accelerated growth and reduction in rotation age (Erasmus et al.2020; Kennedy1995; Long...
The boards consist mainly of wide‐ringed juvenile wood. Norway spruce and Sitka spruce of this material show only small differences in drying properties and they are accordingly analysed together. The boards are prone to severe twisting causing low‐grade boards and a high percentage of rejection ...

However, spruce wood had retentions at the lowest levels with other treated chemicals. Highest retentions were obtained with the wood specimens of a alder tree followed by beech and scots pine woods in general.M. Kemal YALINKILIÇErgün BAYSAL...
