Abstract
Endophytic fungi are generally found in plants as beneficial microbial flora, establishing a symbiotic relationship with them and enhancing their resistance and promoting growth. To study the effect of endophytic fungi on Camellia oleifera C. Abel. growth, four endophytic fungi strains were isolated from rhizomes of C. oleifera and co-cultured with C. oleifera seedlings individually in sterile soil for 49 days: Didymella sp. (DS), Fusarium sp. (FS), Penicillium sp. (PS), and Clonostachys rosea (CR). The experimental results showed that bioactivities of four fungal stains differed, but all exhibited the promotion of quercetin accumulation and reduction of quercetin glycosides after co-culture with C. oleifera seedlings. DS, FS and PS significantly increased the leaf area of C. oleifera, and all of the experimental groups were more than 50% heavier than the Control (CON). Our results demonstrate the prospective utility of endophytic fungi in C. oleifera production with the capacities to enhance productivity and accumulation of plant metabolism products
