Influência do diâmetro das toras de madeira de Eucalyptus spp. nas propriedades físicas

Abstract

This study focuses on analyzing the influence of Eucalyptus log diameter on its physical properties, particularly moisture content and density. The main objective was to understand how the diameter affects these characteristics and its relationship with dry mass. To achieve this objective, an experimental study was conducted using a completely randomized design (CRD). The methodology involved the analysis of Eucalyptus wood, where moisture content was determined following NBR 14660 and NBR 14929 standards. The basic wood density was obtained according to NBR 11942. The dry mass of each sample was calculated from the obtained data. The results of this study demonstrated an influence of Eucalyptus log diameter on its physical properties of moisture content and density. The correlation analysis revealed a significant positive relationship between diameter and dry mass, indicating that an increase in diameter is associated with an increase in the dry mass of the wood. Thus, this study emphasizes the relevance of diameter as an important factor to be considered in the analysis of moisture content and density of Eucalyptus wood throughout its development.
