摘  要:
以泾阳县主栽的酿酒葡萄赤霞珠和北醇为试材,研究了距地面40、801、20 cm结果部位成熟果实的糖、酸、总酚、单宁及花色素苷含量。结果表明:赤霞珠和北淳在结果部位高度距地面80 cm时,葡萄果实中的还原糖、单宁、总酚及总花色素苷含量均显著高于40 cm及120 cm。单宁和总酚含量在80 cm部位高度表现最高。说明,结果部位过高或过低均不利于葡萄果实中糖分和酚类物质的积累及果实中酸的条件。综合比较,在陕西泾阳,赤霞珠和北醇均以80 cm结果部位的果实品质最好。

摘  要:
Taking Cabernet Sauvignon and Beichun grape as test material,the sugar,acidity,total phenols,tannins and anthocyanin content of mature fruit set heights above the ground of 40,80,120 cm were studied.The results showed that the reducing sugar,tannins,total phenolics and total anthocyanin content of grape fruit of above the ground 80 cm was significantly higher than those of the 40 cm and 120 cm.The total phenolic and tannin highes content was above the ground 80 cm.Illustrate the mature fruit set heights above the ground of high or low were not conducive accumulation of grape sugar and phenolic compounds and acid degradation.Comprehensive comparison,the quality of grapes from fruit set height 80 cm resulted in the best fruit quality for Cabernet Sauvignon and Beichun in Jingyang of Shaanxi.
