Abstract:
To obtain biocontrol fungus for Alternaria panax,the antifungal effects of one strain of endophytic fungi isolated from leaves of healthy ginseng were screened and evaluated by using dual-culture method,and the taxonomic assignment of the screened strain was identified based on the morphological characters and ITS sequence analysis. The results of dual-culture showed that one of the endophytes marked as FS-01 had good antifungal effects and the inhibitory rates of FS-01 strain to A. panax was( 60. 21±0. 12) %.The hyphae junction of the both strains,A. panax dissolved,broke and winded,while the hyphae of FS-01 strain remained normal. The inhibitory rates of non-sterilized FS-01 strain fermentation liqud was( 13. 94±0. 21) %. Strain FS-01 identified as Chaetomium globosum.
