摘要：Small wood specimens selected from six slash pine (Pinus elliottii) trees were inoculated with brown-rot and white-rot fungi and then evaluated for static modulus of elasticity (MOE) and dynamic MOE (MOEsw). The experimental variables studied included a brown-rot fungus (Gloeophyllum trabeum) and a white-rot fungus (Trametes versicolor) for six exposure periods (2, 4, 6, 8, 10, and 12 weeks). The MOEsw was tested by a stress wave timer prior to static bending and the results were compared via regression analyses. Regression analyses indicated good correlations between static MOE and MOEsw. The R-2 ranged from 0.66 to 0.80 for non-decayed, brown-rot, white-rot, and all the specimens. (C) 2016 Elsevier Ltd.
