Thirty Copaifera spp. trees were selected to extract oleoresins over 24 hours, using a 1.91 cm (¾ inch) auger. In addition, data were collected on tree size and the edaphic characteristics of the topsoil around of each tree. Principal components analysis was used to verify the relationships between variables and a regression analysis was used to verify variables that may be best to predict oleoresin yield. After the principal components analysis, the only variable related to the oleoresin yield was the stem height, which had the best adjusted coefficient of determination (0.84) and relative standard error (13.11%). We found the yield of oleoresin from Copaifera spp. in primary a forest had a significant and positive correlation with the stem height, whereas no significant correlations were found between yield, or any other dendrometric or topsoil variables studied 2019 artículo científico 1405-0471 https://www.redalyc.org/articulo.oa?id=61762764008 https://www.redalyc.org/journal/617/61762764008/ https://www.redalyc.org/journal/617/61762764008/html/ https://www.redalyc.org/journal/617/61762764008/61762764008.epub https://www.redalyc.org/journal/617/61762764008/movil 10.21829/myb.2019.2531475 en http://www.redalyc.org/revista.oa?id=617 Madera y Bosques application/pdf Instituto de Ecología, A.C.
