Vis spectroscopy and CIELAB parameters of six wood species of the Fabaceae family marketed in the Brazilian Amazon

The aim of this study was to evaluate the potential colorimetry characterize six species (Hymenolobium petraeum, Dipteryx odorata, Ormosia sp., Enterolobium maximum, Hymenaea courbaril e Pseudopiptadenia suaveolens) Fabaceae family. Wood samples were collected in extractivist communities Pará state, Brazil. Colour data obtained randomly on three anatomical sections, along with reflectance spectra range 360–740 nm. All analyses carried out RStudio. In general, similar for all species. However, Principal Component Analysis results, P. suaveolens stood out. colorimetric parameters L*, b* and C*, radial are more important colour results majority wood samples. Colorimetry spectroscopy showed characterizing some Therefore, technique can serve as a support tool better identification group, contributing reduction ecological socio-economic damage.
