Abstract: Bolting and flowering are the important events in the transition from vegetative growth to reproductive growth of plants, and also affect the formation of flower moss in cabbage vegetables. Chinese cabbage vegetables, as long-day crops sensitive to photoperiod, regulate the time of bolting and flowering by sensing changes in photoperiod, which in turn affects the quality, yield and other agronomic traits of the crop, and influences their ecological adaptability to photoperiod. Chinese cabbage vegetables sense photoperiod through photoreceptors and transmit it to the circadian clock, converting light signals into flowering signals to promote flowering. By inducing the expression of key genes in photoperiod, such as CONSTANS（CO） and FLOWERING LOCUS T（FT）, the flowering time can be further regulated. This paper reviews the research progress in the influence of photoperiod on the flowering period of Chinese cabbage, analyzes the regulatory mechanism of photoperiod on the flowering period of Chinese cabbage vegetables, and integrates the molecular mechanism of the photoperiod pathway in regulating the flowering time of plants, providing a theoretical reference for further breeding of high-quality Chinese cabbage varieties.
