摘要: 以天津地区栽培的8个葡萄品种为试材,分别测定了外在品质(单果重、横径、纵径、果形指数)和内在品质(可溶性糖、可溶性固形物、含水量、可滴定酸、VC、糖酸比),然后进行相关分析。结果表明:8个葡萄品种的果实品质呈显著差异;单果重与横径呈极显著正相关;横径与果形指数呈极显著负相关;纵径与VC含量呈显著正相关、与可溶性固形物呈极显著负相关、与果形指数呈显著正相关;果形指数与VC呈极显著负相关;可溶性糖与可溶性固形物呈显著正相关;主成分分析综合排名为:‘葡之梦’>‘紫甜无核’>‘夏黑’>‘玫瑰香’>‘美人指’>‘阳光玫瑰’>‘蓝宝石’>‘新疆无籽露’,其中,‘葡之梦’果实的综合品质最优,‘新疆无籽露’最差。

Abstract: The external quality(single fruit weight, transverse diameter, longitudinal diameter, fruit shape index)and internal quality(soluble sugar, soluble solid, water content, titratable acid, VC, ratio of sugar to acid)were measured with eight varieties of grapes, respectively. By comparing the differences of fruit quality in eight different varieties, this study screens high quality grapes and provides theoretical basis for grape nutrition diagnosis. The result showed that the fruit quality of 8 grape varieties showed significant difference; correlation analysis showed that the correlation between single fruit weight and transverse diameter was significantly positive;there was a significant negative correlation between transverse diameter and fruit shape index;the longitudinal diameter was positively correlated with the content of VC, negatively correlated with the soluble solids, and positively correlated with the fruit shape index;fruit shape index was negatively correlated with VC;there was a significant positive correlation between soluble sugar and soluble solids;the comprehensive ranking after principal component analysis:‘Portugal's Dream’>‘Purple Sweet Seedless’>‘Summer Black’>‘Muscat Hamburg’>‘Manicure Finger’>‘Sunshine Rose’> ‘Sapphir’>‘Xinjiang Seedless Dew’. The best comprehensive quality is the fruit of ‘Portugal's Dream’ and the worst is ‘Xinjiang Seedless Dew’ .
