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

ABSTRACT:

Background

Orchids maintain a symbiotic relationship with mycorrhizal fungi in the lifecycle. Previous reports indicated that diverse mycobionts may have different roles during orchid growth and development. Although various mycorrhizal fungi have been isolated from Dendrobium roots and protocorms, little is known about their specific effects on seed germination and seedling growth. To understand the specific role of isolated fungal strains (i.e., Tulasnella and Sebacina), we used symbiotic culture to compare the effect of 6 fungal strains on seed germination and seedling growth of Dendrobium officinale, an important Chinese medicinal orchid.

Results

In symbiotic germination tests, 6 fungal strains (4 Tulasnella strains and 2 Sebacina strains) promoted seed germination with
