Diversity of Endophytic Fungi from Three Aquatic Plants and Their Antagonistic Activities in vitro / 微生物学通报

ABSTRACT

155 endophytic fungi were isolated from Equisetum arvense L.,Impatiens chinensis L. and Myriophyllum verticillatum L. They were identified to 26 taxa. The antagonistic activities of these isolates against 6 isolates of plant pathogenic fungi were tested on the medium,and 37(23.9%) isolates were activitive against one or more phytopathogens. The percentage of antifungal active isolates from E. arvense L.,I. chinensis L. and M. verticillatum L. were 13.9%,29.2% and 37.1%,respectively. It was lower than that of terrestrial plants. The active isolates were mainly belonging to 5 genera including Cladosporium,Trichoderma and Geotrichum.
