兰科药用植物共生真菌促进种子萌发研究进展

Advances on orchid symbiotic fungi promoting seeds germination

兰科植物种子细小如尘、无胚乳、存在萌发障碍,在自然条件下需要依赖共生真菌提供碳源、氮源、水及其他营养物质才能萌发。本文以相关研究文献为基础,对国内外兰科植物种子促萌发真菌研究历程、种类及共萌发过程中营养物质传递机制等方面进行综述,为兰科植物资源保护和再生、人工栽培及深入开展共生机制的研究提供参考。

Orchidaceae seeds are tiny,without endosperm and must depend on suitable mycorrhizal fungi for carbon nutrients,nitrogen,water and other nutrient sources to germinate in natural conditions.Research progress of the development of endophytic fungi on seed germination,a various of endophytic fungi on seed germination and the nutrition relationship between nutrition sources and endophytic fungi are reviewed to provide a reference for orchid plant rapid propagation and conversation.
