Color Variation of the Teak Wood as a Function of Density and Extractive Content

ABSTRACT The objective of this study was to evaluate the effect of density and extractive content on color variation of teak (Tectona grandis L. f.) wood from plantation of different tree-spacing. Color analyses were performed on radial and tangential sections of heartwood and sapwood by using a CM 2600d spectrophotometer on the L*a*b* color space. Density and extractive content were determined following the ASTM D2395 and ASTM D1105 standards. The wood from larger tree-spacing had higher density and extractive content. In the radial section, denser heartwoods had more yellow hue, while in tangential section, they are darker and had less yellow hue. Denser sapwoods are darker and had more red hue in both sections. Darker woods and with more red hue presented higher extractive content.
