Povezava med razkrojenostjo bukovine in globino prodora igle Pilodyn 6J: Correlation between degradation of Beech wood and penetration of Pilodyn 6J needle

Assessment of white rot decay is one of the most important issues for appropriate treatment of infested wooden commodities, particularly damaged constructions. Pilodyn is a well-established tool for assessing density of several commercially important plantation species, therefore we were interested in its suitability to evaluate the rate of decay as well. The Pilodyn measurements performed on common beech wood (Fagus sylvatica), exposedto three white rot fungi (Trametes versicolor, Hypoxylon fragiforme andPleurotus ostreatus) according to the modified EN 113 procedure, indicate correlations between Pilodyn needle penetration and mass loss. Ocenjevanje razkrojenosti lesa zaradi delovanja gliv bele trohnobe je pomembno za pravilno ukrepanje pri sanaciji lesenih izdelkov, še posebno nosilnih lesenih konstrukcij. Pilodyn je splošno uporabno orodje za vrednotenje gostote lesa številnih komercialnih lesnih vrst, zato nas je zanimalo, ali je primeren tudi za oceno razkrojenosti lesa. Meritve z napravo Pilodyn so bile opravljene na bukovini, ki je bila za različna časovna obdobja izpostavljena glivam bele trohnobe (Trametes versicolor, Hypoxylon fragiforme in Pleurotus ostreatus) v skladu s standardom SIST EN 113. Rezultati kažejo, da med izgubo mase zaradi delovanja gliv razkrojevalk in globino prodora igle Pilodyn obstaja povezava.
