Abstract: In order to study the effects of regulated deficit irrigation (RDI) technique on Muscat hamburg grape berries and corresponding wine,and provide theoretical basis for accurate water management technique.The changes of basic physical and chemical composition,phenolic contents of grape berries and corresponding wine under different RDI degree were analyzed,as well the quality of grape berries and wine were evaluated objectively by principal component analysis.The results showed that RDI increased total phenolic and tannin content,but decreased total anthocyanin,total flavonoid and total flavanol content in grape berries.With the deficit degree aggravated,the variance tendency of phenolic composition content was different between grape berries and corresponding wine.Except R1 (80% of conventional water supply),other RDI increased total phenolic and tannin content in wine.In addition,all RDI treatment increased total flavonoid and total flavanol content.Comprehensive evaluation showed that grape berries and wine possessed best quality under R2 condition (70% of conventional water supply).
