摘　　要：[Objectives]To investigate the mechanism of endophytic fungi mediating the plant growth and promoting the accumulation of secondary metabolites in Camellia oleifera.[Methods]Four strains of endophytic fungi isolated from the rhizomes of C.oleifera were co-cultured with C.oleifera seedlings individually in sterile soil for 49 d:Didymella sp.(DS),Fusarium sp.(FS),Penicillium sp.(PS),and Clonostachys rosea(CR).[Results]The biological activities of the four fungal strains differed,but all exhibited the ability to promote quercetin accumulation while simultaneously reducing quercetin glycosides after co-culture with C.oleifera seedlings.The DS,FS and PS treatments resulted in a significant increase in the leaf area of C.oleifera,with all of the experimental groups exhibiting a weight increase of over 50%compared to the control(CON)group.[Conclusions]Our findings demonstrate the potential utility of endophytic fungi in the production of C.oleifera,highlighting their capacity to enhance both productivity and the accumulation of plant metabolites.
