The comparison of properties of European beech Fagus sylvatica (L.) in different stage of degradation caused by wood-decay fungi

| Summary: | This work focus on comparison of biological degradation of wood caused by wood-decay fungi (white and brown rot). Test samples were made of European Beech Fagus sylvatica (L.). As wood-decay fungi were used Trametes versicolor (L.) Lloyd (white rot) and Serpula lacrymans (Wulf. Ex Fr.) Schroet (brown rot). Aim of this work was comparison of rate of propagation of wood-decay fungus and degradation of wood in time. After termination of the test was made comparison of intensity of degradation between both fungi species. Weights of test samples were diminishing for both groups of wood-decay fungi during three months. Moisture content increased in direct proportion with time. Compression strength in direction of wood fibers of tested samples was diminishing. Samples tested by Serpula lacrymans had the fastest decrease of compression strength after first and second week of degradation. Samples tested by Trametes versicolor had different course. Compression strength significantly decreased after first month and third month of degradation. On the other hand module of elasticity of both tested groups was diminishing already during first and second week of degradation. Generally, it is possible to say that Trametes versicolor has more significant impact on changes of mechanical characteristic of wood, because it causes degradation of all chemical constituents of wood. |
