Abstract: Flowering is an important sign of changing to reproductive growth for plants. Therefore, the formation of flower organs is important for the transmission of genetic information. Tea plant is a valuable cash crop species originated from the southwestern China, whose active blossoms last a long period. In production, the consumption of large amount of nutrients by exuberant reproductive growth seriously affects the yield and quality of tea. On the contrary, in cross breeding, tea plant has the features of self-incompatibility and low seed fertility. In order to gain insight into the timetable of floral bud differentiation and development, influencing factors and molecular regulation mechanisms, it is necessary to disclose the flowering mechanism of tea plant to provide a theoretical basis for fine breeding, high-efficiency production and improving breeding efficiency. Currently, researches on tea plant flowering had made some progresses, but not deep and systematic enough. This paper introduced recent advances in flowering regulation in tea plant and other plant species, flower bud differentiation and floral development. Useful thoughts for current problems and future research directions in tea plant flowering were also provided.

Key words: tea plant, flowering induction, floral bud differentiation, floral development
