| description | Biomass measurements allows knowledge about processes like matter and energy movement, carbon sequestration and storage, among others. Therefore, the objective was to analyze the distribution of structural components of Pinus patula biomass in the green twig stage, as well as the compartments in clearcutting stripe sites at Ixtlán de Juárez, Oaxaca. In 2014, nine sites of 400 m2 each were located using selective sampling and tree inventory was applied. Destructive sampling of 90 trees in the green twig stage was used in order to obtain samples of each structural component, which were subsequently analyzed by regression, to estimate the biomass content per tree and unit of area. The biomass of other compartments (necromass, mulch, bushes and litter fall) of the site was quantified. Variance analysis and mean tests (Tukey, 0.05) were applied for the biomass compartments according to the tree density. The regression models showed adjustments between 0.79% and 97% by structural component and total tree, using inventory variables (diameter at breast height and total height). The high recommended density (> 1500 trees ha-1) presented the largest biomass stores in stem (8048.3 kg ha-1), branches (141.3 kg ha-1), leaves (146.2 kg ha-1) and roots (1350.0 kg ha-1). The clearcutting silvicultural treatment at seven years of its application favors the natural regeneration of the forest with 11.91 t ha-1 of biomass distributed in different compartments. |

El cálculo de biomasa permite el conocimiento de procesos como movimiento de materia y energía, fijación y almacenamiento de carbono, entre otros. Por lo tanto, el objetivo fue analizar la distribución de la biomasa por componentes estructurales de Pinus patula en fase de vardascal, así como de los compartimentos en las áreas tratadas con matarrasa en Ixtlán de Juárez, Oaxaca. En 2014 se ubicaron de forma dirigida nueve sitios de 400 m2 cada uno, para realizar un inventario dasométrico y donde se realizó muestreo destructivo de 90 árboles en fase vardascal para obtener muestras de cada componente estructural; posteriormente se analizaron mediante regresión para estimar el contenido de biomasa por árbol y unidad de superficie. Se cuantificó la biomasa de otros compartimentos del sitio como necromasa, mantillo, arbustos y follaje caído. Se realizó un análisis de varianza y pruebas de medias (Tukey, 0.05) para observar diferencias en acumulación de biomasa de los compartimentos, utilizando como variable clasificatoria la densidad arbórea. Los modelos de regresión mostraron ajustes entre 0.79% y 97% por componente estructural y 97% en total árbol, al utilizar variables de fácil medición en campo (diámetro normal y altura total). La densidad alta recomendable (>1500 árboles ha-1) presentó los mayores almacenes de biomasa en fuste (8048.3 kg ha-1), ramas (141.3 kg ha-1), hojas (146.2 kg ha-1) y raíces (1350.0 kg ha-1). El tratamiento silvícola matarrasa a los siete años de su aplicación favorece la regeneración del bosque con 11.91 t ha-1 de biomasa distribuidos en diferentes compartimentos.
