Comparison of quality and flavor between on-tree storage and cold storage of Satsuma 'Youliang'.

ABSTRACT: This study investigates the effects of on-tree storage (OTS) on the quality and flavor of Satsuma 'Youliang' compared with cold storage (COS). Fruit quality was assessed based on sugar-acid ratio and juice flavor profiles. Comparative analysis revealed a progressive decline in soluble sugar content under COS, while OTS effectively preserved sugars, resulting in a higher sugar-acid ratio than COS-treated fruits. During storage, OTS fruits maintained significantly higher levels of sucrose, fructose, and malic acid than COS fruits. Additionally, OTS fruits exhibited a greater variety and higher concentrations of volatile organic compounds (VOCs), contributing to enhanced flavor. Transcriptome analysis indicated that OTS reduced sugar loss by upregulating soluble sugar metabolism-related genes
