RT Journal Article SR Electronic A1 Holan, Jiří A1 Merenda, Lukáš T1 Comparison of the properties of the Spruce wood Picea abies L. (Karst.) in various state and rate of degradation by wood-destroying fungus Serpula lacrymans Schröter JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 56 IS 5 SP 81 OP 88 DO 10.11118/actaun200856050081 UL https://acta.mendelu.cz/artkey/acu-200805-0011.php AB This article deals with the change of mechanical properties of the Spruce wood (Picea abies L. Karst.) which was exposed to the attack of the wood-destroying fungus Serpula lacrymans Schröter.An activity of the wood-destroying fungus has negattive effect on the wood and its properties. Growth of the wood-destroying fungus causes degradation of the chemical components of wood. Due to this the mechanical properties are changed and strength of the degraded wood is decreasing with extend of the activity time of the wood-destroying fungus. Together with this Serpula lacrymans Schröter causes the weight-shortage.For tests in this article have been chosen the times of one, two and three months of the wood-destroying fungus attack. And then have been established weight-shortage and determined the strength of the degraded wood with Serpula lacrymans Schröter.
