摘要
目的:筛选抗人参根部病原菌的优良木霉菌株。方法:通过不同培养基培养,对10株木霉的生物学特性进行比较;通过平板对峙试验,对木霉抗人参疫病菌、人参锈腐病菌和人参立枯病菌能力进行分析。结果和结论:绿色木霉Tv04-2和哈茨木霉Th3080不仅在土壤浸液培养基和PDA培养基上生长良好,而且对3种病原菌均表现出较高的抑制率。木霉在不同的光照条件及不同的pH下生长速度存在显著性差异。除Tv04-2对菌虫绝霸不敏感外,木霉菌株对人参病害防治中大多数常用杀菌剂敏感。
Objective： To screen the Trichoderma spp. for strong antagonist against ginseng root pathogens. Method ： The biological characters of ten Trichoderma strains were compared by culturing on different media. And their antagonistic activity against Phytophthora cactorum, Cylindrocarpon destructans and Rhizoctonia solani were measured on PDA. Result and Conclusion： Tv04-2 and Th3080 showed a good growth on soil solution medium and PDA,and also showed high inhibitory efficacy to the three pathogens. The two Trichoderma strains showed different growth rate under light conditions and pH. Trichoderma strains were sensitive to most fungicides used in ginseng root disease controlling,however Tv04-2 was not sensitive to the fungicide Junchong Jueba.
