| 摘要: |
| 为探究林下参内生真菌球毛壳菌(Chaetomium globosum)FS-01菌株对人参病原菌的抑菌作用,该研究在实验室条件下,测定了FS-01菌株菌丝、发酵液和孢子悬浮液对人参黑斑病菌(Alternaria panax)、人参菌核病菌(Sclerotinia schinseng)、人参灰霉病菌(Botrytis cinerea)、人参立枯病菌(Rhizoctonia solani)、人参根腐病菌(Fusarium solani)5种人参病原菌的抑制作用。结果表明:内生真菌球毛壳菌FS-01对5种病原菌均有抑制作用,其中,对人参黑斑病菌的抑制作用最高,为30.80%,其次是人参立枯病菌、人参菌核病菌、人参根腐病菌和人参灰霉病菌; 发酵液抑菌实验结果表明,在加入内生真菌球毛壳菌FS-01菌株发酵液的PDA培养基上,对人参灰霉病菌的抑制作用最高,为82.09%,其次是人参菌核病菌、人参黑斑病菌、人参立枯病菌和人参根腐病菌; 孢子抑菌实验结果表明,在加入内生真菌球毛壳菌FS-01菌株孢子悬浮液的PDA培养基上,对人参黑斑病菌的抑制作用最高,为83.72%,其次是人参灰霉病菌、人参立枯病菌、人参菌核病菌和人参根腐病菌。综上结果认为,内生真菌球毛壳菌FS-01菌株对人参病原菌均有很高的抑菌作用,可作为人参病原菌的生防菌株资源。 |

| Abstract: |
| To study the inhibitory effects of Chaetomium globosum strain FS-01 against Alternaria panax, Sclerotinia schinseng, Botrytis cinerea, Rhizoctonia solani and Fusarium solani of ginseng pathogens, mycelia, fermentation broth and conidia suspension were tested in laboratory. The results showed that Chaetomium globosum FS-01 had certain inhibitory effects against five kinds of ginseng pathogens by confront culture. Among them, the highest inhibition rate to mycelia growth of Alternaria panax, reached 30.80%, followed by Rhizoctonia solani, Sclerotinia schinseng, Fusarium solani and Botrytis cinerea; On the PDA plate mixed with Chaetomium globosum FS-01 fermentation broth, the highest inhibition rate to mycelia growth of Botrytis cinerea, reached 82.09%, followed by Sclerotinia schinseng, Alternaria panax, Rhizoctonia solani and Fusarium solani; On the PDA plate mixed with Chaetomium globosum FS-01 conidia suspension, the highest inhibition rate to mycelia growth of Alternaria panax, reached 83.72%, followed by Botrytis cinerea, Rhizoctonia solani, Sclerotinia schinseng and Fusarium solani. Endophytic fungi FS-01 strain had a significant inhibitory effects, it could be utilized as a biological control resource inhibiting ginseng pathogens. |
