内生真菌对兰科药用植物种子萌发作用研究进展

摘要

兰科植物种子细小,无胚乳,自然条件下需与适宜的内生真菌共生才能萌发.近年来,大量研究结果表明,内生真菌能够为兰科药用植物种子萌发提供必要的碳源、氮源等多种营养物质.本文对内生真菌为兰科药用植物种子提供的营养物质进行总结,并对二者的营养关系进行了综述.%Orchid seeds are tiny,without endosperm and must depend on suitable endophytic fungi to germinate under natural conditions.More and more studies have shown that endophytic fungi can provide the necessary carbon nutrients,nitrogen and other nutrient sources for the seed germination of medicinal plants of Orchidaceae.The research progress concerning nutrients provided by endophytic fungi for seeds of orchid medicinal plants are reviewed,and the nutritional relationships between endophytic fungi and orchid seed germination are discussed.
