Identification of wood‐decay fungi and assessment of damage in log depots of Western Black Sea Region (Turkey)

Abstract

The aim of this study was to determine and quantify the wood‐decay fungi found on logs of forest tree species (beech, oak, hornbeam, Scots pine and fir) stored in log depots located in six different provinces in the Western Black Sea Region of Turkey. Additionally, it was aimed to determine the natural durability of some important wood species against the most commonly detected wood‐decay fungi. Eighteen families, 31 genera and 45 species belonging to the division Basidiomycota were detected; Antrodia crassa was identified for the first time in Turkey. The abundance of Panus neostrigosus, Polyporus meridionalis, Trametes hirsuta, T. versicolor and Stereum hirsutumincreased significantly with the holding time of the logs (r = 0.99, 0.87, 0.53, 0.57 and 0.78, respectively, p < 0.05). The majority of the fungal species were detected on logs stored in depots for 4–6 years (66%). The percentage of fungal species found on the logs with a holding time of three years or less was 29%, whereas the percentage for those detected on logs stored for seven or more years was 31%. Among the wood species, the greatest number of fungal species (29) and highest amount of fungi (2,539) occurred on beech wood. Natural durability tests showed that T. versicolor caused the greatest loss of wood mass, with an average of 23%. Field studies and natural durability tests performed in the laboratory showed that beech wood lost the most mass among the timber species studied.

Identification, diversity and host specificity of the wood‐decay fungi in major sawmill depots of north‐eastern Bangladesh

“…Earlier studies in other countries have reported similarly that temperature, relative humidity, wood contact with soil and damp ground in the depots influence the abundance of wood-decay fungi and the severity of decay (Mueller et al, 2004;Talley et al, 2002;Yalçin et al, 2019). Fungal abundance and species variations have been reported as host-specific in several other studies (Deflorio et al, 2008;Malakani et al, 2014;Yalçin et al, 2019), corroborating the findings in the current work.…”

“…Samples were returned to the laboratory, carefully dried at 40-45°C for 2 and 3 days to prevent deterioration (Yalçin et al, 2019) and finally stored in polythene bags for further studies.…”

“…The biological degradation of wood biomass in the depots caused by wood‐decay fungi is a major concern because of associated economic loss and quality degeneration (Sivrikaya & Can, 2014; Yalçin et al, 2019). After harvesting trees from the forests, logs are taken to sawmill depots for processing and trading.…”

Decay Resistance of Carbonized Wood Surfaces

“…When the weight loss of the control samples of the wood species were examined, the weight losses were found higher in pine wood exposed brown rot than beech wood exposed white rot. This is due to the differences in the enzyme systems of fungi [12].…”

“…Basidiomycota bölümüyle ilgili olarak, araştırma alanına yakın çevre ve komşu bölgelerde yapılan çalışmaların bulgularıyla mevcut çalışma arasında %7,84-21,52 düzeyinde (Tablo 1) benzerlik bulunmaktadır [3], [15], [16], [33]- [39]. Tablo 1'e göre Kocaeli yöresi için takson sayıları ve ilgili çalışmalar arasındaki benzerlik %21,52, Bartın-Küre Dağları Milli Parkı bölümü için %16,92 [36] olup yakın çevresi Bolu ve Düzce yöresinde 26 ortak taksonla en yüksek sayıya ulaşılmasına rağmen Yenmez Zehirli benzerlik oranı %10'dur [16].…”
