Un model al variaţiei în raport cu vârsta a infradensităţii medii a trunchiului arborilor de molid [A model of variation depending on age of the mean of the trunk infradensity for spruce trees]

Abstract

The paper presents the results of the research carried out in even-aged spruce stands regarding the density of wood. This research brought up some unknown aspects that can be considered as new contributions concerning the variation way of wood density, one of the most important wood quality components. Using an original method to determine the infradensity and a special methodology for data treatment, it was possible to establish a model predicting intratree variation of wood infradensity based on the relationship between this characteristic and the cambial age, ring width and relative height on the trunk of spruce trees.
