Abstract：Yellow peaches are highly susceptible to postharvest decay.To explore an effective preservation strategy，this study investigated the effcts of pre-harvest spraying of sodium dehydroacetate on‘Jinxiu’yellow peaches.The decay index，firmness，color difference，and other quality indicators were evaluated under 4 C cold storage and subsequent 25∘C shelf-life conditions. Additionally，high-throughput sequencing technology was employed to analyze the treatment’s impact on fruit qualityand fungal diversity.The results demonstrated that atthe end of the shelf-life period，the decay index of the sodium dehydroacetate-treated group decreased by 22.12% compared to the control group，while fruit firmness increased by 18.92% ．Furthermore，the treatmentefectivelydelayed thedecline in titratableacidity，total solublesolids，and free water content.Highthroughput sequencing revealed that sodium dehydroacetate treatment reduced fungal diversity and richness in both the peel and flesh during cold storage.It notablyaltered the fungal community structure of the fruit and suppressed the relativeabundance of potential pathogenic fungi，including Diaporthe，Cladosporium，Alternaria， andFusarium.In conclusion，the pre-harvest application of sodium dehydroacetate can efectively extend the shelf life of‘Jinxiu’yellow peaches.
