Effect of different mycobionts on symbiotic germination and seedling growth of Dendrobium officinale, an important medicinal orchid.

Tulasnella and Sebacina strains could promote seed germination and seedling growth of D. officinale with different efficiencies. Our results suggest a non-specific mycorrhizal association and development-dependent preference. Our data provide the basic knowledge for use of different fungal strains in conservation and/or production practices of D. officinale.
