Dormancy status under environmental conditions and RNA-seq sampling dates. a Evaluation of bud break percentage under forcing conditions was carried out for three sweet cherry cultivars displaying different flowering dates: ‘Cristobalina’, ‘Garnet’ and ‘Regina’ for the early, medium and late flowering cultivars, respectively. The dashed and dotted lines correspond to the dormancy release date, estimated at 50% of buds at BBCH stage 53 [35], and the flowering date, respectively. b Pictures of the sweet cherry buds corresponding to the different sampling dates. c Sampling time points for the transcriptomic analysis are represented by coloured stars. Red for ‘Cristobalina, green for ‘Garnet’ and blue for ‘Regina’
