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.
