The aim of this study was to evaluate the effect of tapping by bark streak method on the physical and chemical properties of wood. Pine wood samples were made from boards with and without the presence of oleoresin pockets. All the boards were selected from trees that were tapped 10-12 times for the oleoresin extraction. The oleoresin was characterized by GC/MS, and the physical and chemical characterization of wood was performed by water absorption tests, dynamic wettability, thermogravimetric analyzes, chemical composition and ATR-IR spectroscopy. Among the main compounds found in the pine oleoresin, α and β-pinene had the highest percentage and are considered products with high commercial value. Regarding wood quality, properties related to water absorption and wettability all decreased due to the large presence of oleoresin. On the other hand, thermal stability of the wood samples decreased with the presence of oleoresin.
