RESUMENL os bosques de Pinus cembroides Zucc, usualmente, han sido segregados del aprovechamiento forestal comercial dadas sus desventajas maderables. Sin embargo, esta especie desempeña un papel importante en la biodiversidad de México. El objetivo del presente estudio fue determinar la concentración de carbono (C) en los principales compartimentos de P. cembroides: raíz, corteza, fuste, ramas, yemas y hojas. La concentración de C total expresado como porcentaje de la biomasa fue determinado con el Solids TOC Analyzer. Los resultados se analizaron en un diseño completamente al azar y mediante comparación de medias de Tukey. El análisis indicó que la concentración de C varía entre los componentes (P < 0.05); la yema tuvo el valor más alto (57.1 %), mientras que el fuste y las ramas registraron los valores más bajos (47.7 y 47.8 %, respectivamente). Los resultados contribuyen a mejorar las estimaciones de C y proveen información importante para definir si los bosques de P. cembroides pueden considerarse como una posible fuente con potencial de mitigación ante el cambio climático y así utilizarlos en un programa de secuestro de C. ABSTRACT P inus cembroidesZucc forests has usually been segregated from commercial logging given their woody disadvantages. However, this species plays an important role in the biodiversity of Mexico. The aim of the present study was to determine the concentration of carbon (C) in the main compartments of P. cembroides: root, bark, stem, branches, buds and leaves. The total C concentration expressed as percentage of biomass was determined with the Solids TOC Analyzer equipment. The results were analyzed in a completely randomized design and Tukey's comparison of means. The analysis of variance evidenced that C concentration varied among components (P < 0.05); the bud had the highest value (57.1 %), while stem and branches recorded the lowest values (47.7 and 47.8 %, respectively). Our results contribute to improving C estimates for this species and provide important information to determine whether P. cembroides forests can be considered as a possible source with mitigation potential against climate change and thus use it in a C sequestration program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
