Abstract:Orchidaceae is one of the largest families in angiosperms, with a wide range of species and wide distribution. Due to its unique flower patterns, rich flower colors, and long flowering period, it has high ornamental value. The flowering time and flower quality are important traits that affect the ornamental value of orchid. How to regulate the flowering period and improve the quality of orchid flowers is of great significance for the production and application of orchid. This article reviews the process of flower bud differentiation, flowering regulation techniques, and molecular regulation mechanisms related to flowering of Orchidaceae plants, combining domestic and foreign research. It summarizes the characteristics of flower bud differentiation and the basic research and technical problems related to flowering regulation in orchids, as well as the flowering pathways related to Orchidaceae plants. It proposes potential research directions for the flowering regulation mechanisms and techniques of orchids. In order to provide reference for the study of flowering regulation, industrial production, and quality improvement of orchids in the Orchidaceae family.
