Aroma is the core characteristic of the flavor quality of Prunus persica, composed of various volatile organic compounds, and its formation is comprehensively influenced by genetic background, cultivation management and post-harvest treatment. In recent years, studies have revealed the key roles of fatty acids, amino acids, terpenoids and esters as the main precursor substances in aroma synthesis, as well as the regulatory mechanism of ethylene on aroma formation. This article clarified the genetic basis of aroma synthesis, reviewed the research progress of aroma components and their biosynthetic pathways in Prunus persica, aiming to provide a the oretical basis for the quality evaluation and quality improvement of Prunus persica. However, at present, the complexity of the aroma synthesis pathway and the influence mechanism of environmental factors on it have not been fully clarified. Future research needs to further analyze the molecular mechanism of aroma synthesis and optimize cultivation and post-harvest processing techniques to enhance the aroma quality of Prunus persica.
