| description | The research works on growth and yield of forest plantations, particularly in coniferous species planted in the different Mexican tropical regions, are scarce. Mathematical models are a useful tool for optimal timber forest resources management. In this work, whole stand explicit prediction models were fitted, with data from permanent plots, to determine the growth and timber yields of forest plantations of Pinus patula var. longepedunculata Loock in the Sierra Sur of Oaxaca. Site index was determined with the polymorphic Schumacher model, which was correlated with the basal area and volume models through seemingly unrelated regression. Families of curves with site indexes of 9 m, 11 m, 13 m and 15 m for height at a base age of 10 years were obtained; in basal area site indexes of 32.9 m2 ha-1, 37.9 m2 ha-1, 42.5 m2 ha-1 and 47 m2 ha-1 at 20 years of age were estimated. In addition, a volume per site indexes of 187.5 m3 ha-1, 234.3 m3 ha-1, 282 m3 ha-1 and 330.6 m3 ha-1 was determined at this latter age. The maximum yield obtained for each site was 10.23 m3 ha-1 year-1, 12.04 m3 ha-1 year-1, 14.12 m3 ha-1 year-1, 16.6 m3 ha-1 yr-1, which suggests rotation periods differents for each site ranging from 19 years to 30 years time. |

Las investigaciones sobre crecimiento y rendimiento de plantaciones forestales, particularmente en especies de coníferas plantadas en las distintas regiones tropicales de México, son escasas. Los modelos matemáticos son una herramienta útil para el manejo óptimo de los recursos forestales maderables. En este trabajo, se ajustaron modelos de predicción explícita de rodal completo, con datos provenientes de parcelas permanentes, para determinar el crecimiento y rendimiento maderable de plantaciones forestales de Pinus patula var. longepedunculata Loock en la Sierra Sur de Oaxaca. El índice de sitio se determinó con el modelo de Schumacher tipo polimórfico, el cual se correlacionó con los modelos de área basal y volumen mediante regresión aparentemente no correlacionada. Se obtuvieron familias de curvas con índices de sitio de 9 m, 11 m, 13 m y 15 m para altura a una edad base de 10 años. En área basal se estimaron índices de sitio de 32.9 m2 ha-1, 37.9 m2 ha-1, 42.5 m2 ha-1 y 47 m2 ha-1 a la edad de 20 años. Asimismo, a esta edad se determinó un volumen por índices de sitio de 187.5 m3 ha-1, 234.3 m3 ha-1, 282 m3 ha-1 y 330.6 m3 ha-1. El rendimiento máximo obtenido para cada sitio fue de 10.23 m3 ha-1 año-1, 12.04 m3 ha-1 año-1, 14.12 m3 ha-1 año-1, 16.6 m3 ha-1 año-1, lo que sugiere turnos diferentes para cada sitio que van de 19 años a 30 años.
