摘要: 以3年生大棚有机栽培和常规栽培的巨峰葡萄为试材,对不同发育时期葡萄果实的平均果粒质量、果粒横径、可溶性糖含量、可滴定酸含量、糖酸比、维生素C含量、成熟期游离氨基酸含量及成熟期果实质地等品质指标进行测定,探究有机栽培对巨峰葡萄果实品质理化指标的影响。结果表明,有机栽培巨峰葡萄的可溶性糖含量、可滴定酸含量、糖酸比、维生素C含量、可溶性蛋白含量及游离氨基酸含量明显高于常规栽培,平均果粒质量、果粒横径在整个果实发育期相差不大,但成熟期略低于常规栽培。总体而言,有机栽培改善了巨峰葡萄的品质。

Abstract: Three year\|old Kyoho grape under organic cultivation and conventional cultivation were used as materials, fruit diameter, fruit weight, total soluble solids (TSS) content, titratable acid (TA) content, TSS/TA and Vitamin C (VC) content in different development periods of grape were determined, free amino acid content and fruit texture in the mature stage were examined. The aim of this research was to explore the effects of organic cultivation on fruit quality in Kyoho grapes. The results indicated that the contents of TSS, TA, TSS/TA, VC and soluble protein in Kyoho grapes fruit under organic cultivation were significantly higher than those of control. Fruit weight and diameter were similar with the control group during the whole development stage, but they were slightly reduced than those of control in the berries mature stage. This study showed that organic cultivation could improve the quality of Kyoho grapes.

Key words: organic cultivation, conventional cultivation, Kyoho grape, fruit quality
