This research was carried out in a plantation belonging to Fábricas de Papel Tuxtepec (FAPATUX) to determine the variations in re-sin content in wood from Pinus caribaea var. hondurensis under two conditions (tapped and untapped trees). Three different stem heights and on four different logging dates (September, November, February and April). Also studied was how stem height, stem diameter and bark width influence resin content. The results showed that resin content is similar at 0.30 m and 1.30 m tree height, but less than at 3.70 m, with 2.92, 2.318, and 1.515%, respectively. Trees tapped at 0.30 m and 1.30 m had statistically higher con-tents compared with untapped trees, exhibiting an average content of 2.677% and 1,862%, respectively. In contrast, at 3.70 m, the-re was no significant difference in resin content between tapped and untapped trees. In September and November, resin content was statistically similar, but higher than those reported in February and April, which were also similar. Stem height and bark width had very little influence on resin content.Keyworks: Tapping, extractive, resin, pulpwood.
