| description | This paper reports on mechanical properties and natural durability of avocado branch wood (Persea americana Mill.) with the objectives of providing a reliable property profile and to promote the rational use of this abundant yet largely neglected natural resource. The mechanical properties (static bending, compression, shear, impact bending) and hardness were determined in accordance with European standards (CEN). Natural durability was assessed according to the European standard EN 350-1 (agar block test) using the white rot fungi Trametes versicolor and Phanerochaete chrysosporium, and the brown rot fungus Postia placenta. Avocado trees yield a low to medium density (0,44-0,54-0,64 g/cm3 at 12% mc) branch wood with below average strength under static bending, compression and tension parallel to the grain and average values for longitudinal shear, impact bending and hardness. The wood is rated non-resistant (class 5 according to EN 350-1) and thus is not suitable for exterior applications unless treated. Considering its property profile and the small dimensions available, avocado wood is recommended for general carpentry, furniture, interior paneling, glue-boards for closets and cabinets, and glue-lams for indoor framework. |

Este artículo presenta información sobre las propiedades mecánicas y la durabilidad natural de madera de las ramas de aguacate (Persea americana Mill.) con los objetivos de proporcionar un perfil de propiedades confiable y promover el uso racional de este recurso natural abundante pero en gran parte abandonado. Las propiedades mecánicas (flexión estática, compresión, cortante, resistencia al impacto) y dureza se determinan de conformidad con las normas europeas (CEN). La durabilidad natural se evaluó de acuerdo con la norma europea EN 350-1 (prueba de bloque de agar) utilizando los hongos de pudrición blanca Trametes versicolor y de hongo de pudrición parda Phanerochaete chrysosporium. Árboles de aguacate producen una madera de rama de baja a mediana densidad (0,44-0,54-0,64 g/cm3 en 12% mc) con valores medios a bajos de flexión estática, compresión y tensión paralela a la fibra y valores medios de resistencia al cortante longitudinal, impacto y dureza. La madera se considera como no resistente (clase 5 según EN 350-1) y por lo tanto no es apta para aplicaciones en el exterior a menos que esté tratada. Teniendo en cuenta su perfil de propiedades y las pequeñas dimensiones disponibles, la madera de aguacate se recomienda para carpintería general, muebles, decoración interior, placas encoladas para armarios y archivadores y madera laminada para usos interiores.
