Near infrared spectra of Tectona grandis (teak) wood samples were collected before measuring physical (density, equilibrium moisture content) and strength (flexural and compressive) properties using conventional methods. Partial least squares regression was used to develop calibration models between measured wood properties and near infrared data. The best near infrared spectra pre-processing methods differed by property. Linear calibration models with high R², low error and high ratio of performance to deviation values were observed from partial least squares analysis for different wood properties. These linear models may be applied for rapid and precise estimation of the properties examined in testing and evaluation procedures for commercially valuable teak wood. 2021 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48565417016 https://www.redalyc.org/journal/485/48565417016/ https://www.redalyc.org/journal/485/48565417016/html/ https://www.redalyc.org/journal/485/48565417016/48565417016.epub https://www.redalyc.org/journal/485/48565417016/movil en http://www.redalyc.org/revista.oa?id=485 Maderas.
