          Abstract

          Phellinus pini es un hongo ampliamente distribuido en el hemisferio norte, el causante de la pudrición roja anular y el más importante que afecta a los árboles en pie de las pináceas. En años recientes se ha detectado la muerte del muchos ejemplares de Pinus greggii en el municipio de Santiago, N. L., lo que se atribuye a la acción de este organismo, con el consecuente deterioro de la masa arbolada del Parque Nacional Cumbres de Monterrey. Por esto, y debido al valor de los bosques de pino en el Estado, se plantearon como objetivos de estudio la determinación del impacto de Phellinus pini , su asociación con algunas variables silvícolas y la estimación del turno patológico. Se establecieron parcelas de muestreo circulares en varias localidades; se evaluó la presencia de pudrición mediante la toma de muestras por medio del taladro de Pressler y su posterior cultivo en cajas Petri en laboratorio. Se tomaron las variables silvícolas de todos los árboles muestreados para determinar los factores que favorecen la incidencia del agente causal y, por último, el turno patológico. La edad fue la variable de mayor correlación, que se confirma con los individuos de edad avanzada, sobre los cuales se advirtió el mayor daño. La incidencia y severidad fue de 11.66 y 12.3% respectivamente; el turno patológico propuesto es de 50 años.

          Translated abstract

          Phellinus pini is widely distributed in the Northern Hemisphere, causes the red ring rot and is the most important agent that affects softwood trees. In recent years the death of many Pinus greggi examples has been detected in Santiago Municipalitiy, Nuevo Leon State, which has been linked to it, with the resulting tree mass deterioration of the Monterrey Heights National Park. Thus, and due to what forests are worth in the State, the following objectives were proposed for this study: to determine the impact of Phellinus pini, its association with some forestry variables and the pathological rotation age. Circular sampling lots were placed in various locations; rottenness was assessed through samples taken by a Pressler boarer, and its eventual laboratory cultivation in Petri boxes. Forestry variables were taken from all the sampled trees to determine the factors that favor the incidence of this pathogen and, finally, the pathological rotation age. Age was the highest correlation variable, which was confirmed with the eldest examples, over which the most severe damages were observed. Incidence and severity were 11.66 and 12.3%, respectively; the pathological rotation age was 50 years.
