Abstract (2. Language): 
Serpula lacrymans (WulfeiuFr.) Schroeter, the dry rot fungus, is generally accepted as one of the most economically important wood degrading fungi in some temperate regions of the world. This study evaluated decay capacity of one isolate of S. lacrymans at four different wood species by the two different decay tests by using wood blocks and stakes. Besides mass losses in the specimens, strength losses and oxalic acid (OA) production in wood by the fungus during decay process were also measured. Higher mass losses were observed in the wood blocks in soil block tests when compared to the stakes in a modified soil bed tests. Losses in modulus of rupture (MOR) in bending were more distinctive in the stakes than mass losses. In the specimens subjected to decay tests, there was a good correlation between both mass losses and OA production and MOR losses and OA production. Further studies are in progress for treated wood specimens to understand copper tolerance ability of S. lacrymans to copper-based wood preservatives.

Abstract (Original Language): 
Kuru çürüklük mantarı Serpula lacrymans (Wıılfen:Fr.) Schroeter, dünyanın ılıman bölgelerinde önemli ekonomik kayıplara neden olan odun tahripçisi mantarlardan biri olarak kabul edilmektedir. Bu çalışma, dört farklı ağaç odunlarından 2 farklı boyutta hazırlanan örneklerde uygulanan 2 farklı çürüklük testinde S. lacrymans''m bir izolasyonunun oluşturduğu çürüklük kapasitesini incelemektedir. Çürüklük sürecinde S. lacrymans tarafından örneklerde oluşturulan ağırlık kayıplarının yanı sıra, direnç kayıpları ve oluşan oksalik asit miktarı da belirlenmiştir. Modifıye edilmiş toprak yatak (soil bed) denemeleriyle karşılaştırıldığında, toprak blok (soil block) denemelerinde odun örneklerinde daha yüksek ağırlık kayıpları meydana geldiği görülmüşütür. Eğilme direnci deneme örneklerinde meydana gelen direnç kayıpları, ağırlık kayıplarına gore çok daha ayırt edicidir. Çürüklük denemelerinde kullanılan örneklerde hem ağırlık kaybı ile oksalik asit üretimi hem de eğilme direnci kaybı ile oksalik asit üretimi arasında iyi bir ilişki olduğu belirlenmiştir. Bakır esaslı emprenye maddelerine karşı 5. lacrymans mantarının emprenyeli odun örneklerinde bakır toleransı kapasitesinin belirlenmesine yönelik çalışmalar sürdürülmektedir.
