Durability of wood of Prosopis laevigata and the effect of its extractives on wood-decaying fungus
The natural durability of mezquite wood (Prosopis laevigata) from four localities in Northeast Mexico was determined using two test, a) terrestrial microcosm (European pre-norm 807) during 32 weeks on a non sterilized vertisol soil and, b) laboratory conditions according to the modify European Norm...

| description | The natural durability of mezquite wood (Prosopis laevigata) from four localities in Northeast Mexico was determined using two test, a) terrestrial microcosm (European pre-norm 807) during 32 weeks on a non sterilized vertisol soil and, b) laboratory conditions according to the modify European Norm 113, the wood was exposed by 16 weeks to Basidiomycetes Trametes versicolor, Coniophora puteana, Irpex lacteus and Pleurotus ostreatus. The natural durability of two methods were determined by mass loss and by the dynamic modulus of elasticity loss (MOEdyn). Additionally the inhibition effect of wood extracts obtained from wood sawdust in either hot water, ethanol or acetone at 100 parts per million (ppm), 1 000 ppm, 5 000 ppm and 10 000 ppm on growth of C. puteana and T. versicolor was also determined. The results showed that P. laevigata wood from the four sites is similar and very resistant to soil contact; the mass lost was ranging from (9 ± 2)% to (17 ± 5)%. The MOEdin lost of P. laevigata was ranging from (20 ± 4)% to (39 ± 11)%, the control species showed values of (91 ± 13)% and (62 ± 15)% respectively. The second method (modify european norm 113) showed mass loss of P. laevigata for the four localities and the four fungi ranging from (0,7 ± 0,5)% to (2,6 ± 3,2)%, placed this species as a class 1 (i.e. very durable) according to the European Norm 350-1. The MOEdyn losses was from (3,8 ± 4,2)% to (19,9 ± 5,6)%. The hot water extracts at 1 0000 ppm concentration inhibited growth of C. puteana and T. versicolor by (83 ± 8)% and (93 ± 6)% respectively. |

Se determinó la durabilidad natural de la madera de Prosopis laevigata de cuatro sitios del Noreste de México mediante a) microcosmos terrestres (Pre-norma Europea 807) en un suelo tipo vertisol durante 32 semanas y b) en condiciones de laboratorio (Norma Europea 113 modificada) al exponer la madera a los hongos Coniophora puteana, Irpex lacteus, Pleurotus ostreatus y Trametes versicolor durante 16 semanas. La durabilidad natural fue cuantificada como pérdida de masa y pérdida de módulo de elasticidad dinámico (MOEdin). Adicionalmente, se determinó el efecto en el crecimiento de los hongos C. puteana y T. versicolor producido por los extractos de la madera de P. laevigata obtenidos por agua caliente, etanol y acetona en concentraciones de 100 partes por millón (ppm), 1 000 ppm, 5 000 ppm y 10 000 ppm. Los resultados indican que P. laevigata es altamente resistente en el microcosmos terrestre, con pérdidas en masa de (9 ± 2)% a (17 ± 5)% y MOEdin de (20 ± 4)% a (39 ± 11)%. En el segundo método, la pérdida en masa producida por los cuatro hongos fue de (0,7 ± 0,5)% a (2,6 ± 3,2)% y clasificada según la Norma Europea 350-1 como clase 1 (muy durable). La pérdida del MOEdin fue de (3,8 ± 4,2)% a (19,9 ± 5,6)%. Los extractos de P. laevigata obtenidos con agua caliente en concentración de 10 000 ppm mostraron el mayor porcentaje de inhibición al reducir el crecimiento de C. puteana (83 ± 8)% y (93 ± 6)% para T. versicolor.
