Abstract:

This study was conducted to investigate the relationship between soil physicochemical properties and fruit quality indicators of five main grape cultivars(‘Summer Black’‘Jumeigui’‘Gold Finger’‘Shine Muscat’‘Zuijinxiang’)grown in five vineyards of Nanjing. The aim was to identify key soil factors influencing fruit quality and to provide a theoretical basis for high-quality grape production. Comprehensive analysis of soil properties and fruit quality traits was performed,followed by principal component analysis(PCA)to evaluate the comprehensive quality of different cultivars. The results indicated that soil mineral nutrients(available nitrogen,available phosphorus,available potassium),exchangeable calcium,exchangeable magnesium,and soil porosity were key factors affecting grape quality. Among the fruit quality indicators,anthocyanin content and soluble solid-to-acid ratio exhibited considerable variation(with coefficient of variation up to 78.61%),indicating high sensitivity to soil conditions. In contrast,fruit shape index and color parameters remained relatively stable. Significant cultivar-dependent responses to soil environment were observed:‘Summer Black’showed strong adaptability and consistently exhibited superior comprehensive quality across all orchards;‘Gold Finger’performed poorly overall;while the quality of‘Jumeigui’‘Shine Muscat’and‘Zuijinxiang’was highly dependent on specific orchard soil conditions(porosity,enzyme activity,etc). PCA further revealed that soil fertility structure and nutrient status jointly regulated grape quality formation. In conclusion,grape fruit quality is determined by the interaction between genetic characteristics and soil environmental factors. Accordingly,it is recommended to implement cultivar-soil matching strategies along with precise fertilization and soil management practices to improve fruit quality and planting efficiency.
