Dormancy is not just a survival strategy, since chilling accumulation is required for proper flowering and arbitrates species adaptation to different latitudes. In spite of the fact that chilling requirements have been known for two centuries, the biological basis behind remain elusive. Since chilling accumulation is required for the normal growth of flower buds, it is tempting to hypothesize that something might be going on at this particular stage during winter dormancy. Here, we characterized flower bud development in relation to dormancy, quantifying changes in starch in the flower primordia in two sweet cherry cultivars over a cold and a mild year. Results show that, along the winter, flower buds remain at the same phenological stage with flower primordia at the very same developmental stage. But, surprisingly, important variation in the starch content of the ovary primordia cells occurs. Starch accumulated following the same pattern than chilling accumulation and reaching a maximum at chilling fulfillment. This starch subsequently vanished during ecodormancy concomitantly with ovary development before budbreak. These results showed that, along the apparent inactivity during endodormancy, flower primordia were physiologically active accumulating starch, providing a biological basis to understand chilling requirements.This research was supported by Ministerio de Economía, Industria y Competitividad (MEIC) – European Regional Development Fund, European Union (AGL2012-40239 and BES-2010-037992 to EF); Instituto Nacional de Investigación Agraria (INIA) (RTA2014-00085-00, RFP2015-00015-00, and RTA2017-00003-00); Gobierno de Aragón – European Social Fund, European Union (Grupo Consolidado A-43).Peer reviewedFrontiers MediaMinisterio de Economía y Competitividad (España)European CommissionCSIC - Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA)Gobierno de AragónConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201820182018info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/161856reponame:DIGITAL.CSIC.
