Longitudinal buckling is a very serious problem in production of solid wood panels assembled of beech lamellae joined alternatively breadthwise and longwise into large-sized blocks. The aim of our work was to identify the main factors causing misshaping of beech dowels in solid wood panels production, with the primary focus on identification of reaction tension wood in dowels and logs. According to our results, the most common source of longitudinal buckling of beech dowels was the presence and non-uniform distribution of tension wood in them. The tension wood occurrence in logs is possible to predict with a considerable confidence based on eccentric pith presence. The tension wood presence and distribution over the cross section are possible to identify if the cross-cut surface has been milled and its moisture content reduced under FSP. The tension wood can be discerned through its lighter hue and pearlescent-white gloss.
