Characterizing the mechanical properties of wood cell walls will lead to better understanding and optimization of modifications made to wood infected by the blue-stain fungi. In this study, in situ nanoindentation was used to characterize the mechanical properties of the cell walls of Pinus massoniana infected by blue-stain fungi at the cellular level. The results show that in situ nanoindentation is an effective method for this purpose and that blue-stain fungi penetrate wood structures and degrade wood cell walls, significantly reducing the mechanical properties of the cell walls. The method can also be used to evaluate and improve the properties of other wood species infected by blue-stain fungi.

表征木质细胞壁的机械性能将有助于更好地理解和优化对蓝染真菌感染的木材的修饰。在这项研究中，原位纳米压痕用于表征在细胞水平上被蓝染色真菌感染的马尾松细胞壁的机械性能。结果表明，原位纳米压痕是实现此目的的一种有效方法，蓝染真菌会穿透木质结构并降解木质细胞壁，从而显着降低细胞壁的机械性能。该方法还可用于评估和改善受蓝染色真菌感染的其他木材种类的性能。
