摘　　要：兰科是被子植物中最大的科之一,物种繁多,分布广泛,因其奇特的花型、丰富的花色和持久的花期,具有极高的观赏价值。兰科植物也是国际上贸易最多的花卉之一,具有极高的经济价值。其开花时间和花朵品质是影响兰科植物观赏价值的重要因素,但由于大部分兰科植物的自然花期与市场需求错位、开花整齐度低、开花品质不佳,极大地限制了兰花产业的发展。因此,如何调控兰花花期、提升兰花花朵品质对兰科植物的生产和应用具有重要意义。本文结合国内外研究对兰科植物的花芽分化进程、花期调控技术及开花相关的分子调控机理进行综述,总结出兰科植物花芽分化的特征、兰科植物花期调控相关基础研究与技术存在的问题、兰科植物相关的开花途径以及蝴蝶兰相关的开花机理与花期调控技术,提出兰科植物花期调控机理和花期调控技术具有潜在研究价值的方向,以期为兰科植物的花期调控研究、规模化生产和品质提升提供参考。Orchidaceae is one of the largest families in angiosperms,with a wide range of species and wide distribution.It has high ornamental value because of its peculiar flower type,rich flower color and long-lasting flowering period.Orchids are also one of the most traded flowers internationally,with extremely high economic value.The flowering time and flower quality are important traits that affecting the ornamental value of orchid.However,due to the mismatch between the natural flowering period of most orchids and market demand,low flowering uniformity,and poor flowering quality,the development of the orchid industry is greatly limited.Therefore,how to regulate the flowering period and improve the quality of orchid is of great significance for the production and application of orchid.This article provides a review of the flower bud differentiation process,flowering regulation techniques,and molecular regulation mechanisms related to flowering in orchid,based on domestic and foreign research.It summarizes the characteristics of flower bud differentiation in orchid,the existing problems in basic research and technology related to flowering regulation in orchid plants,the flowering pathways related to orchid,and the flowering mechanism and flowering regulation techniques related to Phalaenopsis.It proposes potential research directions for flowering regulation mechanisms and techniques in orchid,in order to provide reference for flowering regulation research,large-scale production,and quality improvement in orchid.
