摘　　要：【目的】研究避雨栽培对葡萄果实品质的影响,以期对葡萄避雨栽培技术的改进提供参考依据。【方法】以6 a生葡萄‘金手指’为试材,调查果粒纵横径及质量、果实可溶性固形物含量和可滴定酸含量、果实着色状况以及香气物质组分等果实品质指标。【结果】避雨栽培条件下,‘金手指’葡萄果粒质量迅速生长期延后1周左右,可滴定酸含量明显下降;果实色泽参数CIRG值为1.23,显著低于对照1.25;检测出醛类为香气物质的主要成分,且较对照增加了1种物质,即3-己烯醛;在醛类物质中,2-己烯醛相对含量最高,较对照增加了17.52%;但在整个观察期内,果粒纵横径和可溶性固形物含量未发现显著差异。【结论】避雨栽培对葡萄着色状况和香气物质组分等指标有一定的影响。【Objective】In order to provide a theoretical basis for the guidance of grape rain-shelter cultivation,the berry quality under rain-shelter cultivation was observed in this research.【Methods】Six-year-old‘Golden finger＇grapevine was used to study the berry quality including berry length,berry width,berry weight,soluble solids,total acidity,skin coloring indexes and aromatic component.【Results】The results showed that under the rain-shelter cultivation condition,the rapid increase period of berry weight delayed about one week,total acid content decreased obviously;CIRG of the skin coloring indexes was 1.23,which was significantly less than that of control 1.25;Aldehydes were the main components of aromatic compounds,and 3-Hexenal was detected only in rain-shelter treatment; The relative content of 2-Hexenal was the highest among aldehydes,which increased by 17.52% compared with control;But the berry length,width and soluble solids content did not show significant difference between the treatment and control.【Conclusion】Skin coloring indexes and aromatic component of the berry changed under rain-shelter cultivation.
