Growth of individual trees of Geoffreea decorticans Burk. in a forest from the Semiarid Chaco, Argentina
The objective of this study was to improve the knowledge on the annual growth rates of Geoffreeadecorticans (chañar), to define the evolution of annual growth increment (IR), diameter at breast height(DAP), normal section (DN) with age, to estimate mean annual (IMA) and annual increment (IA) in orde...

| description | The objective of this study was to improve the knowledge on the annual growth rates of Geoffreeadecorticans (chañar), to define the evolution of annual growth increment (IR), diameter at breast height(DAP), normal section (DN) with age, to estimate mean annual (IMA) and annual increment (IA) in orderto propose guidelines for proper management of the species. The study was carried out in a semiaridChaco forest, at Quebrachos Park, Alberdi, Santiago del Estero Province, Argentina. For epidometricstem analysis, 16 vigorous trees were selected based on DAP greater than 15 cm and clean bole. Fromeach tree cross-sections of 5 cm thickness were removed at 0,30 m; 1,30 m above ground, and at theend of the stem. Definition of ring boundaries and ring with measuring were made with computerizedequipment ANIOL and the computer program CATRAS. The data were analyzed with the statisticalsoftware package INFOSTAT. Chañar presented well-defined annual growth rings. The average thicknessof rings is 5,90 mm (1,79 – 16,55). The age of completion for DAP was determined to be the five years, and NS is achieved after 37 years.This growth rate can define the managementon short rotations. |

El objetivo del trabajo es contribuir al conocimiento del crecimiento de árboles individuales deGeoffreea decorticans (chañar), definir en función de la edad la evolución del incremento radial (IR),diámetro a la altura del pecho (DAP), sección normal (SN) y estimar el incremento medio (IMA) y anual(IA) con el fin proponer directrices para la correcta gestión de la especie. El estudio fue realizado en unbosque del Chaco Semiárido, Parque Los Quebrachos, Alberdi, Santiago del Estero, Argentina. Para elanálisis epidométrico de fuste se derribaron 16 individuos que cumplían con la condición de: DAPsuperior a 15 cm; fuste sin defectos; de buena vitalidad. De los árboles derribados se extrajeron rodajasde 5 cm de espesor, a las alturas de 0,30 m; 1,30 m y final del fuste. La marcación y medición de anillosse efectuó con el Equipo Computarizado ANIOL y el programa CATRAS. Los datos fueron analizadoscon el software estadístico IFOSTAT. El chañar presenta anillos de crecimiento bien demarcados. Elincremento radial promedio es 5,90 mm (1,79-16,55). La edad de culminación del crecimiento en DAPes a los 5 años y en SN se logra a partir de los 37 años. Este crecimiento permite definir el manejo enrotaciones cortas.
