Description

Trabalho apresentado em Abril de 2009, em Praga no Forestry, Wildlife and Wood Sciences for Society Development. Pine oil can be obtained from α-pinene and this is one of the constituents from gun-turpentine. Is a natural product and os known for its insecticide, bactericide and fungicide proprieties. In this study dry pinewood samples, cut in radial section, were impregnated with pine oil and stabilised at room temperature. Two degradative fungi were tested: Trametes versicolor and Trichoderma citrinoviride. Sterilized polypropylene vessels filled with glass beads and distilled water were prepared. Wood samples, deposed over the glass beads surface, were inoculated with fungal plugs collected from actively growing colonies and maintained at 25ºC in the dark during 29 days. The fungi development was assessed with image analysis system using a digital camera. Analysis of variance (ANOVA) was use to study the effect of impregnation treatments, sterilization and fungal treatments.
