Flower Bud Dormancy in Prunus Species

摘要: In Prunus species, developing flower buds survive winter by entering a dormant stage. However, dormancy is not just survival strategy, but also prerequisite for proper flowering and fruiting. spite of its importance the fact that cold requirements are empirically known number cultivars, what occurs during at cellular molecular level remains somewhat mystery. Here we review information available on genetic control possible physiological mechanisms involved in bud species. Genes regulation appear to play some role, interactions between these genes still being determined, as well epigenetic this process. From perspective, vegetative appears be associated with isolation both cell organ level, could case buds, studied. Finally, characterization biological factors impacting processes will clearly contribute our understanding dormancy.
