L'andamento della fibratura nell'abete rosso. Un caso di studio in Trentino

The grain alignment was analyzed aver 24 plants coming from the "Foresta Demaniale di Cadino" (state-owned forest of Cadino) in Val di Fiemme (TN). Measures were taken considering the radial direction, from the pith to the bark, and the whole height of the plant. Even if the grain angles have a high variance, the general alignment within the radial direction can be ascribable to the conifers scheme, that is defined by a first part of left-hand grain (initial stages of the tree), followed by a slope of the grain, from a left-hand to aright-hand spiral, at maturity. A similar behavior has been noticed along the whole stem.
