The study of tree growth in forest plantations for timber use must be complemented by the description of wood characteristics to serve both foresters and wood technologists. Studies based on growth rings allow for the acquisition of growth records in diameter, height, shape, and volume with annual resolution, facilitating the assessment of their relationship with environmental factors. This is crucial for thinning and harvesting decisions in forest plantations. Evaluating differences in wood characteristics in axial and radial directions provides valuable information for analyzing their optimal potential use. This study evaluated the growth of Araucaria angustifolia (Bertol.) Kuntze using dendroecological techniques. Additionally, wood anatomy and basic density were examined at four axial positions and three radial levels as quality indicators. Stem analysis revealed that CAIDBH ranged f...
