INFLUENCE OF TECHNOLOGICAL CHARACTERISTICS IN THE COLOR OF EUCALYPT WOOD

ABSTRACT

Due to importance of the color of the wood as a component of its description this study was undertaken to verify the influence of chemical components in the color of wood of various clones of eucalypt. The amount of lignin and polyphenols in the wood, the fibres dimensions and its specific gravity were determined. The colorimetric measurements were made through a specterphotometer Data Color 200d Microflash. It was verified by the characteristics of the wood studied, that the amount of extractives, basically polyphenols, had high correlation with the color of the wood.

Key words:
technological characterization; color; eucalypt
