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 R2 ranged from 0.66 to 0.80 for non-decayed, brown-rot, white-rot, and all the specimens. ? 2016 Elsevier Ltd
