 en NATURAL DECAY RESISTANCE OF SIX AMAZON WOOD SPECIES IN SOIL BLOCK TESTS
da Silva Alves, Marcus Vinicius; da Costa, Alexandre Florian; da Silva Espig, Daniele & do Vale, Ailton Teixeira

Abstract

This study evaluated the natural resistance of six Amazonian wood species: Aspidosperma desmanthum check for this species in other resources (Araracanga), Parinari excelsa check for this species in other resources (Parinari), Mouriri callocarpa check for this species in other resources (Miraúba), Marmaroxylon racemosum check for this species in other resources (Angelim-rajado), Peltogyne paniculata check for this species in other resources (Roxinho) e Astronium check for this species in other resources sp. (Muiracatiara) against Pycnoporus sanguineus check for this species in other resources , a white rot fungus, and Gloeophyllum trabeum check for this species in other resources , a brown rot fungus. Testing was performed based on the American Society for Testing and Materials - Standard Method for Accelerated Laboratory Test of Natural Decay Resistance of Woods - ASTM D2017/81(86). Results showed that all tested wood species were classified as very resistant to both decay fungi, except the wood of Aspidosperma desmanthum, which demonstrated to be very resistant to Pycnoporus sanguineous and resistant to Gloeophyllum trabeum. The wood of Peltogyne paniculata showed the best performance against Pycnoporus sanguineous, whereas the wood of Astronium sp. presented the best results when submitted to Gloeophyllum trabeum attack.

Keywords

 pt RESISTÊNCIA NATURAL DE SEIS ESPÉCIES DE MADEIRAS DA REGIÃO AMAZÔNICA A FUNGOS APODRECEDORES, EM ENSAIOS DE LABORATÓRIO

Resumo

O presente trabalho avaliou a resistência natural das madeiras de Aspidosperma desmanthum check for this species in other resources (Araracanga), Parinari excelsa check for this species in other resources (Parinari), Mouriri callocarpa check for this species in other resources (Miraúba), Marmaroxylon racemosum check for this species in other resources (Angelim-rajado), Peltogyne paniculata check for this species in other resources (Roxinho) e Astronium check for this species in other resources sp. (Muiracatiara) aos fungos causadores de podridão-branca Pycnoporus sanguineus check for this species in other resources e podridão-parda Gloeophyllum trabeum check for this species in other resources , em ensaios de laboratório. A determinação da resistência natural foi feita por meio da avaliação da perda de massa, com base na norma da American Society for Testing and Materials – Standard Method for Accelerated Laboratory Test of Natural Decay Resistance of Woods – ASTM D2017/81(86). Todas as espécies se apresentaram muito resistentes aos fungos Pycnoporus sanguineus e Gloeophyllum trabeum, exceto Aspidosperma desmanthum que mostrou ser resistente ao fungo de podridão parda. A espécie Peltogyne paniculata mostrou-se a mais resistente ao fungo Pycnoporus sanguineus, enquanto Parinari excelsa apresentou-se como a espécie de menor resistência. A maior resistência ao fungo Gloeophyllum trabeum foi observada para a madeira de Astronium sp., enquanto que a espécie Aspidosperma desmanthum se mostrou como a menos resistente.

Palavras-chave
