Abstract

Endophytic fungus No.1028 isolated from the stem of Gingko plant was cultured in vitro,the metabolites of which were found to have strong inhibitory effect on several crop pathogenic fungi.The inhibition rates were 66.7%,48.3%,64.6%,36.5%,57.1% and 23% on pathogenic fungi Alternaria solani,Fusarium oxysporum,Colletotrichum lindemuthianum,Colletotrichum gloeosporioides,Thanatephorus cucumeris and Rhizoctonia Solani respectively.The effects of carbon,nitrogen and inorganic ion on the growth and metabolism of this endophytic fungus were studied.Corn starch,soybean starch and Na~+ could obviously promote its growth and metabolism for significantly producing more active ingredients.
