The study aimed to analyze the natural resistance of Tachigali vulgaris wood to Postia placenta fungus that causes brown rot. Nine trees were collected and from basal log we prepared six samples of each tree measuring 25 mm x 25 mm x 9 mm (radial, tangential and axial) from base to top. The samples were kept in contact with the fungus in an acclimatized room for 14 weeks, when samples were dried and measured weight loss. T. vulgaris wood showed high resistance to P. placenta as the greatest mass loss was 12.13%. An indirect correlation of 82.9% was observed between the basic density and wood durability, but it was not observed effect of base to top position on durability.Downloads
