| description | One of the most important activities in the management of forest resources is the extraction of wood, this being the most important variable due to its economic value. The objective of the work was to adjust taper-volume models for Pinus pseudostrobus Lindl. in the Corona del Rosal ejido in southern Nuevo León, Mexico. 968 pairs of data from 82 trees, coming from non-destructive measurement methods, were employed using the Criterion RD1000® dendrometer. Fang's segmented model turned out to be the most accurate for the species studied, obtaining an adjusted coefficient of determination of 0.98 for the diameter at different sections on the stem and 0.97 for the commercial volume; in the root mean square error and coefficient of variation statistics, the system surpassed the Max and Burkhart and Parresol models. The dendrometric shape from neiloid to paraboloid presented similar inflection points between 6% and 9%, while the change from paraboloid to cone occurs between 88% and 91% of the total height. The models were corrected for autocorrelation and heteroscedasticity to decrease the standard error of the parameters. The results continued to be favorable for the Fang system to predict diameters at any height and volume at any diameter, which constitutes a support for decision-making in the development of forestry activities. |

Una de las actividades más importantes en el manejo de los recursos forestales es la extracción de volumen maderable, siendo la variable de mayor importancia debido al valor económico que tiene. El objetivo del trabajo fue ajustar modelos de ahusamiento-volumen para Pinus pseudostrobus Lindl. en el ejido Corona del Rosal, municipio de Galeana, Nuevo León, México. Se emplearon 968 pares de datos de 82 árboles, provenientes de una medición no destructiva utilizando el dendrómetro Criterion RD1000®. El modelo segmentado de Fang resultó ser el más preciso para la especie, se obtuvo un coeficiente de determinación ajustado de 0.98 para el diámetro a diferentes secciones sobre el fuste y 0.97 para el volumen comercial; en los estadísticos raíz de error medio cuadrático y coeficiente de variación, el sistema superó a los modelos de Max y Burkhart y Parresol. La forma dendrométrica de neiloide a paraboloide presentó puntos de inflexión entre 6% y 9%, mientras que el cambio de paraboloide a cono ocurre entre 88% y 91% de la altura total. Los modelos fueron corregidos por autocorrelación y heterocedasticidad para disminuir el error estándar de los parámetros. Los resultados continuaron siendo favorables para el sistema Fang para predecir diámetros a cualquier altura y volumen a cualquier diámetro, lo que constituye un apoyo para la toma de decisiones en el desarrollo de las actividades forestales.
