| description | Aboveground biomass accumulation and allocation to the structural components of trees is crucial in managed forests, both in terms of timber productivity and the reactivation of different ecosystem processes. In this study, we analyzed the pattern of accumulation of aboveground total biomass and its allocation among stems, branches, bark and foliage in a chronosequence of managed Pinus patula forests in Zacualtipán, Hidalgo. Total aboveground biomass (TAB) and its allocation to structural components were estimated by using allometric equations in stands with different numbers of years since harvest, in different years of measurement (2005, 2008 and 2012). We found that the TAB increased with time since harvest, with highly significant differences (p<0.0001) among stand ages. The stand with 30 years since harvest showed an aboveground biomass (AB) of 178.1 Mg ha-1 which was only 20% lower than that estimated for the stand without harvest (AN), indicating that a managed forest could reach levels of aboveground biomass similar to those of the AN, but in less time. Aboveground biomass allocation was made in the following order: stem> branches> bark> foliage. Allocation favored the stem as a commercial timber product, which is the main objective of these managed forests. The pattern of aboveground biomass allocation among the structural components of the trees reflects the fact that forest management in temperate forests operates as an important alternative for the recovery of degraded forests. Because of climate change, it can also represent an appropriate strategy for carbon sequestration and mitigation of carbon dioxide emissions. |

La acumulación y distribución de biomasa hacia los componentes estructurales de los árboles es determinante en bosques manejados, tanto en términos de productividad maderable como en la reactivación de diversos procesos ecosistémicos. En el presente estudio se analizó el patrón de acumulación de biomasa aérea total (BAT) y su asignación hacia fuste, ramas, corteza y follaje en una cronosecuencia de un bosque de Pinus patula bajo aprovechamiento forestal en Zacualtipán, Hidalgo. Mediante el uso de ecuaciones alométricas se estimó la BAT y por componente estructural de los árboles en rodales con diferentes años después de la cosecha, en diferentes años de remedición (años 2005, 2008 y 2012). Se encontró que la BAT aumentó con el tiempo después de la cosecha, con diferencias estadísticas significativas (p < 0.0001) entre los rodales. El rodal de 30 años después de la cosecha presentó una biomasa aérea total (BAT) de 178.1 Mg ha-1, la cual resultó solo 20% menor a la observada en el rodal sin cosecha (AN), lo que indica que un bosque bajo aprovechamiento podría alcanzar niveles de biomasa aérea similares a la del AN, en un menor tiempo. La asignación de biomasa aérea (BA) presentó el siguiente orden: fuste> ramas> corteza> follaje. Esta asignación de BA fue favorecida hacia fuste como un producto maderable comercial, objetivo principal de estos bosques bajo producción. El patrón de asignación de BA entre los componentes estructurales de los árboles puede ser incorporado como base para el diseño de prácticas silvicuturales en los programas de manejo forestal y contribuir en la evaluación de la sustentabilidad de los bosques. Además, puede clarificar el papel de los bosques regenerados después de los aprovechamientos en la fijación y almacenamiento de bióxido de carbono atmosférico.
