摘要
兰科植物的种子细小,是所有被子植物中最小种子类型之一,只具备一种不被胚乳包围且小而不发达的胚,在其生命周期的整个过程中,特别是在营养资源匮乏的早期阶段,对共生真菌的依赖性非常强.共生真菌与兰科植物形成菌根联合共生体为种子萌发、原球茎生长发育、幼苗分化以及成年植株生殖生长提供所需的营养物质.本研究对兰科植物共生真菌的研究历程与概况、菌根互作关系、多样性与专一性、促生作用以及应用前景等方面进行了综述,并在此基础上进行展望,以期为兰科植物野生资源保育与开发、人工栽培生产以及生防菌与菌肥研发等研究提供参考.
Abstract
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.
