Abstract

Abstract 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.

韩国旌善地区5种木材的自然耐久性和真菌多样性

摘要全球变暖引起的气候变化增加了木材腐烂的风险。了解木材固有的耐用性对于长期使用至关重要。因此，对五种重要的韩国木材（山奈落叶松、赤松、红栎、栓皮栎和锯齿栎）的自然耐久性进行了评估。此外，还对从每个木桩中分离出的真菌多样性进行了调查，以比较和分析天然耐久性的差异。五种木材的自然耐久性最高的是山奈落叶松和锯齿栎，其次是栓皮栎、红栎和赤松。总共收集了306个真菌分离株，包括16种子囊菌门、22种担子菌门、15种接合菌门和8个未鉴定的物种，它们在木桩的不同位置占主导地位。在具有高耐久性的两种木材中观察到较少的担子菌门多样性。此外，不仅担子菌门的分离，而且子囊菌门和结霉菌门的分离都可能影响木材的劣化，并解释其与木材耐久性的关系。在气候变化时代，木材腐烂的风险正在增加，这些发现有望有助于提高韩国有用木材的耐用性。
