Reproductive meristems and embryos display dormancy mechanisms in specialized structures named respectively buds and
seeds that arrest the growth of perennial plants until environmental conditions are optimal for survival. Dormancy shows
common physiological features in buds and seeds. A genotype-specific period of chilling is usually required to release
dormancy by molecular mechanisms that are still poorly understood. In order to find common transcriptional pathways
associated to dormancy release, we analyzed the chilling-dependent expression in embryos of certain genes that were
previously found related to dormancy in flower buds of peach. We propose the presence of short and long-term dormancy
events affecting respectively the germination rate and seedling development by independent mechanisms. Short periods of
chilling seem to improve germination in an abscisic acid-dependent manner, whereas the positive effect of longer cold
treatments on physiological dwarfing coincides with the accumulation of phenylpropanoids in the seed [-]
