Abstract
Se describe un método para evaluar troncos para predecir propiedades estructurales y/o tendencia al combado de madera aserrada u hojas de madera que podrían ser producidas a partir de un tronco dado. El método puede ser utilizado en un puesto en un bosque, un área de clasificación o comercialización, en línea en un aserradero, o en otras ubicaciones a lo largo de la ruta del bosque al aserradero. Permite decisiones en cuanto a si un tronco debe ser dirigido a un aserradero para fabricación de madera aserrada o para otras aplicaciones tales como vigas, hojas de madera o astillas (chips) para pulpa. Se ha hallado que el ahusamiento del tronco se correlaciona tanto con la rigidez como con la propensión al combado de la madera aserrada cortada a partir de un tronco dado. Un alto ahusamiento conduce a madera aserrada combada y baja rigidez de la madera aserrada u hojas de madera. La correlación con el ahusamiento es mayor si se mide sobre la longitud total del tallo del tronco talado, antes de que sea trozada a medida para el aserradero o en bloques para hojas de madera. Otras características geométricas del tronco, tales como encorvamiento o irregularidad en la sección transversal, pueden ser combinadas con el ahusamiento en una ecuación de regresión multivariable para incrementar la precisión de la predicción. Esto puede ser fácilmente logrado con un escáner convencional utilizado en un área de clasificación o en el aserradero.
