• Resumen

  • Assesing the potential for forest carbon (C) capture requires accurate assesments of C in live tree tissues. Usually has been assumed a conversion factor of 50% of the tree biomass. The objective of the present study was to determine C concentration in the main compartments of Arbutus bicolor S. González, M. González et P. D. Sørensen. This species has recently been described and plays an important role un the boi diversity of Mexico´s forest. The total C content expressed as a percentage of biomass was determined with the Solids TOC Analyzer equipment. Analysis of variance evidenced that C concentration varied among compartments.Tukey´s test high lighted that fruits and leaves had the highest values (51.51% y 50.96%, respectively), in contrast with roots recorded the lowest values (46.22%), whereas remaining compartments were non significantly different and showed similar behavior with intermediate values.

    We conclude that C content varies substancially among tree compartments. Thus, a 50% generic value is anoversimplification of limited application in regards to estimation of C storage. Our results contribute to improving C estimates and providing a more reliable account of the mitigation potential of forests on climate change.
