英文摘要	Endodormancy is one of the most studied physiological processes in perennial plants like apricot. This period is vital both for the tree survival against the adverse climatic conditions of winter and for obtaining a proper flowering and fruit set. Many studies have remarked the importance of chill accumulation as the limiting factor for endodormancy release. The increase of mean temperatures caused by climate change has been seriously endangering this process during the last decades. Because of this, plant growth regulators for promoting endodormancy release have spread worldwide. However, due to the toxicity and the irregular efficiency, there is a great necessity of developing new environment-friendly regulators for promoting endodormancy release. In this 3-year study, we applied four different commercial plant growth regulators to the Flopr & iacute;a apricot cultivar. Two of them, Broston (R) and Erger (R) were the most effective ones to advance endodormancy release. The physiology and biochemistry behind these treatments were studied by a non-target metabolomic and expression analysis in flower buds. Metabolic groups, like phospholipids, only varied in treated samples, whereas others like by-products of L-Phe metabolism, or ABA significantly varied in both types of samples throughout endodormancy release. Finally, to validate these results, solutions of phospholipids, phenylpropanoids, or ABA, among others, were applied for the first time to apricot trees, showing, i.e., that phospholipids treated-trees released from endodormancy two weeks earlier than control. This study aims to be an initial stage for the elaboration of environmentally safe regulators in apricot, with a potential in other Prunus and temperate fruit tree species.
