M.J. Silva & A.M.G. Azevedo and <em>Machaerium paraguariense </em>Hassl., species of the Fabaceae family, native to the Araucaria Forest in the state of Santa Catarina, southern Brazil. Discs at breast height were collected from three trees of each species and the colorimetric parameters (L*, a*, b*, C* and h) and visible spectra were evaluated in different radial position of the trunk (near bark, intermediate and near pith) and three different anatomical sections (transversal, radial and tangential surfaces). Mean values of hue angle (h) among the colorimetric parameters resulted in the highest potential for species discrimination. With respect to radial trunk position and anatomical section, parameters a* (green-red) and h were not statistically different, independent of the wood samples evaluated. For other parameters (L*, b* and C*), each species presented distinct results. Principal component analysis with second derivative of visible spectra discriminated all species. Colorimetry associated with chemometrics allowed to distinguish <em>I. vera</em>, <em>M. campestris </em>and <em>M. paraguariense</em>.</p>}, journal={Maderas-Cienc Tecnol}, author={Vieira, Helena Cristina and dos Santos, Joielan Xipaia and Souza, Deivison Venicio and Rios, Polliana D’ Angelo and Bolzon de Muñiz, Graciela Inés and Morrone, Simone Ribeiro and Nisgoski, Silvana}, year={2021}, month={Dec.}, pages={1–12} }
