BIOLOGICAL, PHYSICAL AND MECHANICAL WOOD

physical and mechanical wood properties of paraíso (Melia azedarach) from a roadside planting at Huaxtla, Jalisco, Mexico. The present study was undertaken with the objective of evaluating the wood quality of 11-year-old paraíso (Melia azedarach) trees from a roadside planting near Huaxtla, Jalisco, Mexico. The biological, physical and mechanical properties studied include density, dimensional stability, strength (bending, compression, tension, shear, impact) and natural durability. The medium density (0.56−0.68−0.76 g/cm3 at 12 % moisture content) wood is similar in strength to true mahogany (Swietenia macrophylla) and is of moderate dimensional stability. Its attractive appearance (colour, figure) resembles that of cedro (Cedrela spp.) and suren (Toona spp.). Heartwood resistance against white rot and brown rot fungi is on average moderate, but quite variable. Based on the property profile established by the present study paraíso wood from trees planted in Mexico appears suitable for the manufacture of decorative veneers sliced and peeled, furniture parts, plywood, glue board, laminates, panelling, window and door framing, general carpentry, and light construction under cover
