真姬菇菌糠提取液对5种食用菌的化感作用

Allelopathy of Spent Substrate Extract of Hypsizygus marmoreus on Five Edible Fungi

采用平板培养法研究了真姬菇菌糠水提液和乙醇提取液对金针菇、灵芝、真姬菇、花脸香蘑和糙皮侧耳等5种食用菌菌丝生长的影响。结果表明,真姬菇菌糠水提液或醇提液对供试食用菌菌丝生长均具有不同程度的影响,水提液有利于糙皮侧耳菌丝的生长;而醇提液则有利于灵芝和金针菇菌丝的生长;2种提取液对花脸香蘑和真姬菇菌丝生长均具有抑制作用。研究结果可为真姬菇菌糠的合理利用提供参考。

The allelopathy of spent substrate extracts including water extract and ethanol extract of Hypsizygus marmoreus on the mycelium growth of five edible fungi, i.e, Flammulina velutipes, Ganoderma lucidum, Hypsizygus marmoreus, Lepista sordida and Pleurotus ostreatus, were investigated using Petri dishes approach. The results indicated that the spent substrate extracts had different effects on their mycelium growth. The mycelium of Pleurotus ostreatus grew better with water extract. The mycelia of Ganoderma lucidum and Flammulina velutipes grew better with ethanol extract. The mycelia of Lepista sordida and Hypsizygus marmoreus were inhibited by spent substrate extracts. The results could provide reference values for rational utilization of the spent mushroom substrate.
