Relationship between various extracted basic densities and wood chemical components inEucalyptus camaldulensis

Abstract

Relationship between various extracted basic densities and wood chemical components were investigated by their within-tree variations inEucalyptus camaldulensis for assistance in the prediction of the properties of wood or wood derived products. Within-tree variation was not observed for basic density because extraneous compounds masked it. However, extractives-free basic density, total extractives-free basic density and extraneous compounds-free basic density were high on the bark side and top parts in the trunk. These extracted basic densities were expected to have significant relationships to the fiber morphology causing the within-tree variations, and to be very important factors for wood industries. These relationships were sought by correlations between extracted basic densities and wood chemical components based on their within-tree variations. Furthermore, fair relationships between extracted basic densities and hemicellulose composition were observed and speculation made as to the relationship to the constituent ratio of cell wall layers.
