QUINTANAR-ISAIAS, Alejandra et al. Wood of Trema micrantha (L.) Blume from Veracruz, México. Madera bosques [online]. 2012, vol.18, n.2, pp.73-91. ISSN 2448-7597.

The microscopic anatomy, hydraulic and mechanical indices of the wood of 28 trees of the species Trema micrantha of four localities in the municipalities of Xico and Coatepec in Veracruz State, Mexico were studied. In addition, macroscopic characteristics such as relative density and moisture content were determined. Results showed that T. micrantha has a mesomorphic xylem characterized by low resistance to cavitation, low values of relative density, low indices for vessel and fiber collapse and a high index of vulnerability. An analysis of variance shows that of all the characteristics studied, only the rate of collapse of the vessels is similar between individuals and populations. Multiple comparison tests show that wall thickness and the number of rays separate populations Bola de Oro and Barrales from the other sites of study. Carpentry tests reveal that wood from T. micrantha is resistant to splitting when nailed, is well suited to assemblage, and thus, it is recommended for use in carpentry in rural areas.
