摘要

Natural resistance of eight wood species from Caatinga, an exclusive Brazilian biome, was evaluated according to [ASTM Standard (2005) D 2017-05. Standard test method of accelerated laboratory test of natural decay resistance of woods.]. Samples were exposed to white rot (WR) and brown rot (BR) fungi, namely to Trametes versicolor (WR), Pycnoporus sanguineus (WR), Gloeophyllum trabeum (BR) and Gloeophyllum striatum (BR). Weight loss, specific gravity and extractive content of each wood species were evaluated. Diptychandra aurantiaca, Pterodon abruptus and Terminalia fagifolia were classified as "highly resistant", while T. fagifolia was "resistant" to T. versicolor only. Machaerium acutifolium was resistant to all fungi. Aspidosperma multiflorum was resistant to WR fungi and Combretum glaucocarpum to a BR fungus. The species Pityrocarpa moniliformis and Swartzia psilonema were moderately resistant.
