Review of Interaction between Orchidaceae and Symbiotic Fungi
Orchidaceae is one of the smallest seed types in angiosperms,with only one small and undeveloped embryo without endosperm.Orchidaceae is highly dependent on symbiotic fungi throughout its life cycle,especial-ly in the early stage when nutrient resources are scarce.The mycorrhizal symbiosis between symbiotic fungi and Orchidaceae provides essential nutrients for seed germination,protocorm growth and development,seedling differ-entiation and adult plant growth.The paper reviewed the research process and profile,mycorrhizal interaction rela-tionship,diversity and specificity,growth-promoting effect and application prospect of symbiotic fungi in Orchi-daceae.And based on this,to provide reference for the conservation and development of wild Orchidaceae re-sources,artificial cultivation and production,as well as the research and development of biocontrol fungi and fun-gal fertilizer.
