- Abstract
The research aimed to evaluate the efficiency of salt solutions (sodium chloride, lithium chloride, sodium carbonate, magnesium sulfate, zinc sulfate, and copper II sulfate) impregnated in Corymbia torelliana and Eucalyptus cloeziana woods on biological resistance to brown rot (Postia placenta) fungus under laboratory conditions. Wood test samples of 2.0 x 2.0 x 3.0 cm (tangential x radial x longitudinal) from each species were taken of the planks obtained in the heartwood region on base-top direction. The samples were impregnated with 5% concentration of solutions and submitted for 16 weeks to the P. placenta fungus under laboratory conditions. The wood of E. cloeziana was more resistant to decay than C. torelliana, both impregnated with salt solutions as not impregnated. The treatments with saline solutions were satisfactory as regards resistance of wood degradation, and may be used as a parameter for the evaluation of the wood, the xylophagous tested fungus.
