筛选诱导白木香产生沉香的真菌的研究

 目的 筛选诱导白木香产生沉香的活性真菌。 方法 野外条件下用真菌接种白木香，利用光学显微镜和扫描电子显微镜分别观察真菌诱导白木香树产生沉香过程中的真菌侵染、定植、真菌与植物的互作情况；用GC-MS检测诱导产生沉香材料中挥发油的主要成分。结果 筛选到三株具有诱导白木香产生沉香的活性真菌，这些真菌的诱导效果尚属首次报道。真菌菌丝能够侵入白木香组织细胞，诱导白木香产生的沉香与天然沉香的化学成分类似。结论 利用本实验得到的3株真菌诱导白木香结香具有重要的理论意义和实际应用价值。

Fungus Inducing the Formation of Agilawood from Aquilaria sinensis

OBJECTIVE To screen the fungi which can induce Aquilaria sinensis to produce active substance.METHODS Fungus was inoculated in the stem of A.sinensis under natural conditions.The penetration and planting of fungus in stem of A.sinensis as well as the interaction of the two organisms were studied by microscope and scanning electron microscopy,and the main ingredients of the volatile oil in induced agilawood were analysed by GC-MS.RESULTS Three active strains inducing the formation of agilawood were obtained,which was reported for the first time in the world.The main ingredients of the volatile oil were similar between the induced agilawood and the natural materials.CONCLUSION It is very important for us to use the fungus in the induction of agilawood and in the sustainable utilization of this special medicinal material.
