Resumen

Background: This study evaluates the anatomical, physical, and colorimetric properties of Gordonia fruticosa (huamanchilca) and Vochysia ferruginea (bella María), two tropical timber species from the montane rainforest of Amazonas, Peru. Samples were analyzed according to radial and tangential anatomical planes to examine their influence on wood properties under dry and saturated conditions. Results: Anatomical analysis revealed diffuse porosity in G. fruticosa and visible porosity with aliform parenchyma in V. ferruginea. Physical tests showed medium basic density values (0.55 and 0.41 g/ cm³, respectively) and similar volumetric shrinkage (~10.8%) in both species. Colorimetric results indicated that drying increases lightness and modifies chromatic coordinates. G. fruticosa showed increased red and yellow saturation after drying, whereas V. ferruginea exhibited a decrease. No significant differences were found between radial and tangential planes in color parameters. Conclusion: These findings contribute to understanding the interaction between anatomical features and moisture content on wood properties, providing valuable information for optimizing industrial drying processes and supporting sustainable management of these tropical species. © (2025), (Federal University of Lavras).
