Abstract:Dendrobium, epiphyticly growing on tree or rock, is one of the largest genus in orchid family, belonging to Dendrobiinae of Epidendroideae. Most of species in this genus have high medicinal and ornamental values. Howerver, the wild species of Dendrobium has been threatened because of over-collection and habitat deterioration in recent years. Dendrobium is one of typical orchid mycorrhizal plants, it needs symbiosisn with mycorrhizal fungi to complete its life cycle under natural conditions. Mycorrhizal fungus have important roles in Dendrobium seed germination and plant growth. the conformation of Dendrobium mycorrhizae, effects and diversity of mycorrhizal fungi in Dendrobium were reviewed, as well as the mycorrhizal technology utilization in Dendrobium. In addition, some ideas based on the current researches are proposed for future studies.
