| 摘 要： | 杏鲍菇是一种重要的具有食用价值和药用价值的真菌，其发酵液中含有大量的次级代谢产物。文章初步探究了杏鲍菇发酵液对尖镰孢菌、链格孢菌、禾谷镰孢菌3种植物病菌的抑制作用。结果表明：发酵液使3种病菌菌丝均表现出溶菌现象；发酵液原液对3种病菌菌丝生长速度及孢子萌发影响最大，其抑菌率依次为尖镰孢菌（92.78%）>链格孢菌（89.76%）>禾谷镰孢菌（87.45%）；其孢子萌发抑制率依次为禾谷镰孢菌（79.45%）>链格孢菌（72.25%）>尖镰孢菌（52.32%）。由此可见，杏鲍菇发酵液中的确存在对植物病菌有抑制作用的物质，进而为生物制剂的开发提供依据。

| Abstract: | Pleurotus eryngii is a very important edible and medical mushroom， whose fermented filtrates contain a lot of secondary metabolites. The inhibition effect of the fermented filtrates from Pleurotus eryngii on the growth of Alternaria alternata， Fusarium oxysporum f.sp.cucmrium and Fusarium graminearum was investigated. The results showed that the fermented filtrates from Pleurotus eryngii showed the lysis phenomenon and it had significant inhibition effects on pathogen mycelial growth and spore germination. The inhibitory rate of the extracts against the mycelial growth showed as Fusarium oxysporum f.sp.cucmrium （92.78%）>Alternaria alternata （89.76%）>Fusarium graminearum （87.45%） and the inhibitory rate against the spore germination were Fusarium graminearum （79.45%）>Alternaria alternata （72.25%）>Fusarium oxysporum f.sp.cucmrium （52.32%）. Therefore， there were the anti pathogenic materials in fermented filtrates of Pleurotus eryngii， which could lay the foundation for the development of bio inhibitor. |
