Uso del método de resistografía para la predicción de la densidad básica de la madera en árboles en pie de Pinus radiata

Abstract: RESUMENEl objetivo de esta investigación fue desarrollar modelos de estimación de la densidad básica de la madera a nivel de árbol completo y a diferentes alturas de árboles de Pinus radiata, a partir de la resistencia de la madera medida con el resistógrafo, a la altura del pecho a 1,3 m sobre el nivel suelo (DAP). Se utilizó una muestra de 29 árboles de 15 años de edad, obtenidos al azar, en un ensayo clonal establecido en la Región del Bío-Bío, Chile. Para cada árbol, en seis diferentes alturas relativas de… Show more

“…The estimation of the wood density by non-destructive methods is performed using devices such as the Pilodyn®, an apparatus that relates the resistance of the wood to the penetration of a pin in its outer parts to obtain data of density, used by Greaves et al (1996), MacDonald (1998), MacKenzie et al (2003), the Resistograph®, an apparatus that determines the strength of the wood in relation to the penetration of a metal drill through the whole diameter of the stem, used by Barría et al (2017), Isik andLi (2003, Rinn et al (1996) and Lima et al (2007), and a motorized extractor for removal of a baguette, a linear sample of wood at the transverse direction of the tree, used by Downes et al (1997) and Raymond and Muneri (2001).…”

“…Barría et al [40] reported a correlation coefficient of 0.65 between WBD (measured at 1.3 m height) and amplitude for Pinus radiata (D. Don). These findings further support the existence of significant associations among mean resistograph amplitude and wood basic density in Eucalyptus species and P. radiata.…”
