Wood blue staining is one of the most common wood defects, which commonly occurs in rubberwood and Masson pine. It not only affects the appearance of the wood, but also its properties. In this study, rubberwood from Xishuangbanna was examined. During the process, blue-stain fungi and endophytic fungi were isolated and identified. The antagonism of biocontrol strains against blue-stain fungi was studied, and their inhibitory effects were evaluated by inoculating the biocontrol strains on non-blue-stained rubberwood. The morphology and distribution of the strains on the wood were observed using polarized light and fluorescence microscopy, infrared spectroscopy, scanning electron microscopy (SEM-EDS), and X-ray diffraction (XRD). The effects of biocontrol strains on the blue stain of the wood were then evaluated. The results showed that at room temperature, the fungus causing the blue stain in rubberwood was identified as , and the biocontrol strains of endophytic fungi isolated were and . It was found that was more effective than in inhibiting the development of . Based on these findings, was suggested as a biocontrol strain for preventing and controlling blue stain in rubberwood.
木材蓝变是最常见的木材缺陷之一，常见于橡胶木和马尾松中。它不仅影响木材外观，还影响其性能。本研究对来自西双版纳的橡胶木进行了检测。在此过程中，分离并鉴定了蓝变真菌和内生真菌。研究了生防菌株对蓝变真菌的拮抗作用，并通过将生防菌株接种到未蓝变的橡胶木上来评估其抑制效果。使用偏光显微镜和荧光显微镜、红外光谱、扫描电子显微镜（SEM-EDS）和X射线衍射（XRD）观察了菌株在木材上的形态和分布。然后评估了生防菌株对木材蓝变的影响。结果表明，在室温下，导致橡胶木蓝变的真菌被鉴定为 ，分离出的内生真菌生防菌株为 和 。发现 在抑制 的生长方面比 更有效。基于这些发现，建议将 作为防治橡胶木蓝变的生防菌株。
