Abstract: Dendrobium is a traditional and precious Chinese medicinal material with“medicine food homology”, and it contains abundant endophytic bacteria. In long-termsymbiosis, endophytic bacteria can promote the growth and development, stress resistance and the synthesis of active metabolites of Dendrobium. This paper briefly describes the current research results of endophytic bacteria resources and their promoting effects on Dendrobium, and prospects the problems and research directions, in order to provide a basis for the development and utilization of Dendrobium and endophytic bacteria.
Keywords: Dendrobium; endophytic bacteria; research progress
