Properties of wood from 7-year-old Cedrela odorata trees of two different populations growing in agroforestry systems with Theobroma cacao
This study evaluated the properties of juvenile wood from 7-year-old Cedrela odorata trees in two populations with the same provenance and planted in an agroforestry system with Theobroma cacao (cacao).

| description | This study evaluated the properties of juvenile wood from 7-year-old Cedrela odorata trees in two populations with the same provenance and planted in an agroforestry system with Theobroma cacao (cacao). The morphological characteristics (diameter at breast height; heartwood, sapwood, bark, and pith percentages; and eccentricity of pith), physical properties (shrinkage, green moisture content, green density, and specific gravity) and mechanical properties (modulus of rupture (MOR) and modulus of elasticity (MOE) in bending, compression stress, Janka hardness, tension stress and shear stress) were determined between two populations. The variation of the physical properties and morphological characteristics at different tree heights was also evaluated. The results showed that there were differences in both populations in terms of bark, pith, volumetric shrinkage, green moisture content, green density, MOR and MOE in bending, longitudinal compression and perpendicular tension. The results showed that population 2 presents better characteristics of growth and quality of wood for structural and furniture uses; hence, this population planted in agroforestry systems has good plantation conditions and wood quality. |

En este estudio se evaluaron las propiedades de la madera juvenil proveniente de árboles de 7 años de Cedrela odorata de dos poblaciones con la misma procedencia, plantadas en un sistema agroforestal con Theobroma cacao (cacao). Se evaluaron las características morfológicas del árbol (diámetro a la altura del pecho, porcentaje de médula, duramen, albura y corteza en relación al área total y excentricidad de la médula), las propiedades físicas (contracciones y contenido de humedad, la densidad verde y el peso específico básico) y las propiedades mecánicas (módulos de ruptura (MOR) y de elasticidad (MOE). De estas últimas, se obtuvieron esfuerzos en compresión longitudinal, tensión paralela y perpendicular, cortante y la dureza. Los resultados mostraron diferencias en las dos poblaciones en porcentajes de corteza, médula, contracción volumétrica, contenido de humedad, densidad verde, MOR y MOE en flexión, así como en la resistencia en compresión longitudinal y tensión perpendicular. Los resultados muestran que la población 2 presenta mejores características de crecimiento y de calidad de la madera, por lo que la población plantada en sistemas agroforestales presenta buenas condiciones de desarrollo y de calidad de madera para su uso estructural o en mueblería.
