摘　　要：检测地卷地衣内生真菌的生防活性。从湖北神农架地卷属地衣中分离获得3株对4种植物病原真菌和水霉病病原卵菌拮抗性好抑制率高的优势生防菌株,分别为Creosphaeria sassafras,Annulohypoxylon multiforme和Penicillium vulpinum;通过液体发酵液及拮抗试验检测了3株地衣内生真菌的生防潜力。结果显示其对病原菌的抑制作用优于常用的生防菌球毛壳菌,在与植物病原真菌的营养竞争过程中占有一定优势。地衣内生真菌可用于植物病害和水霉病的防治。Three strains of endolichenic fungi identified as Creosphaeria sassafras, Annulohypoxylon multi-forme and Penicillium vulpinum, were isolated from samples of Peltigera species collected from Shennongjia forest region in Central China. The anti-pathogenic microorganic activities of them were assessed by the methods of culturing with their fermentation broth and plate confrontation co-culture against four pathogenic fungi. The results showed that some strains had more obvious inhibitory effect than positive control strain Chaetomium globosum. We conclude that some endolichenic fungi have the potential for use in developing a novel therapy to control plant disease and saprolegniasis.
