| Abstract:Objective To study the effects of endophytic fungus Epichlo? bromicola SH09 on the plant growth and accumulation of active components in Salvia miltiorrhiza, and improve the quality of medicinal plant S. miltiorrhiza. Methods E. bromicola SH09 solid bacterial fertilizer was prepared and co-cultured with S. miltiorrhiza for 60 d and 120 d. Four morphological indexes, fresh weight of roots, dry weight of roots, and the contents of four tanshinones and two phenolic acids in the roots of S. miltiorrhiza from treated group and control group were assayed, respectively. Results After 60 d and 120 d co-culture, E. Bromicola SH09 significantly increased the tiller number, plant height, leaf number, leaf area, fresh weight of roots, dry weight of roots, and the content of tanshinones and phenolic acids in S. miltiorrhiz. Conclusion The endophytic fungus E. bromicola SH09 can effectively promote the plant growth and improve the accumulation of active components in S. miltiorrhiza, which not only broadens the new ecological functions of endophytic fungi, but also improves the quality of medicinal plant S. miltiorrhiza. |
