Abstract:
Six strains of endophytic fungi were isolated from three samples of Evernia mesomorpha by scraping cortex method,which were collected from the Great Hinggan Mountains.Taking five pathogenic fungi as antagonistic indicator,anti-pathogenic fungal activities of six strains were studied by the plate confrontation method.The results showed that based on the morphological observation of colonies and ITS sequence analysis,all six strains of endophytic fungi were classified to Sordariomycetes,Ascomycota.Among them,strains FF-3 and FF-4 were identified as Hypoxylon fuscum,strain FF-7 was identified as Engyodontium album,strain FF-2 was identified as Hypoxylon sp.,strain FF-6 was identified as Xylaria sp.,strain FF-9 was identified as Chaetomium sp.,strains FF-2(Hypoxylon fuscum)and FF-6(Xylaria sp.)had inhibitory effect on Lichtheimia ramosa.Strain FF-6 had inhibitory effect on Plectosphaerella cucumerina.Strain FF-6 had the obvious inhibitory activity against pathogenic fungi,which could form an obvious antagonistic strip.The maximum width observed was 7.00 mm in the experiment.Strains FF-2 and FF-6 were expected to be candidated biological control fungi of plant pathogenic fungi.
