摘　　要：兰科植物大多花色艳丽极具观赏性,有些常作为药用,因此,具有重要的社会、经济和药用价值。但其种子细小无胚乳,自然条件难以正常萌发生长,大多通过营养繁殖,或通过人工组培等技术实现快速繁育。不过在特殊情况下,部分兰科植物在自然条件下也可以实现种子繁殖,即在内生菌的共生帮助下种子可正常成苗。而在这过程中,内生菌为种子提供了营养、激素和增强植物对环境胁迫的抗性等作用;科学促进这种良好协作关系的建立,有利于快速、高效培育优质兰科植物种苗。因此,本文通过兰科植物与其内生菌互作方面的研究分析对其种子共生萌发机制进行综述,并以兰科植物天麻、白及和铁皮石斛为例,阐释共生萌发技术在产业化上的实际生产应用价值,实现兰科植物种质资源保护并促进其科学开发利用。Most Orchidaceae plants have bright and highly ornamental flowers,some of which are often used for medicinal purposes,and therefore have important social,economic,and medicinal value.However,its seeds are small and have no endosperm,so it is difficult to germinate and grow normally under natural conditions.Most of them are bred rapidly through vegetative reproduction or artificial tissue culture.However,in special circumstances,some orchid plants can also achieve seed reproduction under natural conditions,where the symbiosis of endophyte helps the seeds to grow normally.During this process,endophyte provide nutrients,hormones,and enhance the plant′s resistance to environmental stress for the seeds,scientifically promote the establishment of such a good collaborative relationship,which is conducive to the rapid and efficient cultivation of high-quality Orchidaceae plant seedlings.Therefore,this article reviews the mechanism of seed symbiotic germination of Orchidaceae plants through research and analysis of their interactions with endophyte.Taking Orchidaceae plants such as Gastrodia elata Bl,Bletilla striata and Dendrobium officinale as examples,the practical production and application value of symbiotic germination technology in industrialization is explained,achieving the protection of Orchidaceae plant germplasm resources and promoting their scientific development and utilization.
