Metabolite-Metabolite Interaction Network in different stages. S1, S2, S3 represent the early, middle, and later stage of the first flower bud differentiation, respectively. S4, S5, S6 represent the early, middle, and later stage of the second flower bud differentiation, respectively. The circles of different sizes represent interactions between metabolites. The larger the circle, the more closely it interacts with other metabolites. The straight lines between the circles represent interactions between metabolites
