Blueberry flower buds cultivated in greenhouses develop during both autumn and spring, with floral induction being a critical process for flowering, influenced by environmental factors. This study aimed to clarify the regulatory mechanisms governing greenhouse blueberries, focusing on similarities differences bud differentiation between spring seasons. Understanding these is pivotal enhancing blueberry production. In this study, we analysed phenotypic characteristics associated observed that short photoperiods markedly affect process. Transcriptomic analyses revealed distinct major metabolic pathways activated compared spring. Seasonal variations carbohydrate metabolism were also noted, sucrose hydrolysis prominent synthesis prevailing The interplay circadian rhythms photosynthesis appeared facilitate allocation of sugars development. Subsequent investigations underscored sensitivity VcCO3 photoperiod. Predominantly localised nucleus, facilitated response activating expression downstream genes, including VcFT, VcLFY, VcAP3, VcSOC1. Furthermore, exhibits close association sugar gene VcSUS, promoting increased concentrations.
