Climate change from global warming raises the risk of wood decay. Knowing the inherent durability period of wood is crucial for long-term use. Hence, the natural durability of five important Korean wood species (Larix kaempferi, Pinus densiflora, Quercus rubra, Quercus variabilis, and Quercus serrata) was evaluated. In addition, the fungal diversity isolated from each wood stake was investigated to compare and analyze the differences in natural durability. The natural durability of the five wood species was determined to be highest in Larix kaempferi and Quercus serrata, followed by Quercus variabilis, Quercus rubra, and Pinus densiflora. Overall, 306 fungal isolates were collected, including 16 species of Ascomycota, 22 species of Basidiomycota, 15 species of Zygomycota, and eight unidentified species, which dominate different positions of the wood stake. Less Basidiomycota diversity was observed in the two wood species with high durability. In addition, the isolation of not only Basidiomycota but also Ascomycota and Zygomycota could affect wood deterioration and explain the association with wood durability. These findings are expected to be useful in improving the durability of useful wood in Korea in an era of climate change, where the risk of wood decay is increasing.

韩国旌善实地试验场中五种木材的自然耐久性和真菌多样性

全球变暖导致的气候变化增加了木材腐烂的风险。了解木材固有的耐用期对于长期使用至关重要。因此，韩国五种重要木材树种的自然耐久性（落叶松,赤松,红栎,栓皮栎， 和锯缘栎）进行了评价。此外，还研究了从每个木桩中分离出的真菌多样性，以比较和分析自然耐久性的差异。这五种木材的自然耐久性被确定为最高的落叶松和锯缘栎， 其次是栓皮栎,红栎， 和赤松。总共收集了 306 株真菌分离株，其中包括 16 种子囊菌门, 22 种担子菌门, 15 种接合菌门，以及八个不明物种，它们主导着木桩的不同位置。较少的担子菌门在两种具有高耐久性的木材品种中观察到多样性。此外，隔离不仅担子菌门但是也子囊菌门和接合菌门可能会影响木材的劣化并解释与木材耐久性的关联。在气候变化时代，木材腐烂的风险不断增加，这些发现预计将有助于提高韩国有用木材的耐用性。
