摘要
本文以红色酿酒葡萄品种‘赤霞珠’‘品丽珠’‘美乐’‘黑比诺’及‘马瑟兰’为试材,在陕西省合阳县气候条件下研究了葡萄成熟过程中浆果的还原糖、总酸的变化趋势,并测定了成熟果实的可溶性固形物、果皮总酚、果皮单宁和花色苷含量,以及穗质量、果梗率、出汁率、种子含量、果穗尺寸、粒质量、果穗紧密度、果实病害与卫生情况。研究表明,5个供试品种成熟果实糖含量以‘赤霞珠’‘美乐’较高,‘马瑟兰’次之,‘黑比诺’‘品丽珠’较低。总酸含量为5.0 g/L左右,成熟系数均大于20。果皮总酚、总花色苷、总单宁含量较高,其中‘赤霞珠’‘品丽珠’‘马瑟兰’的表现较好。总体来看,‘赤霞珠’‘美乐’和‘马瑟兰’可作为陕西合阳地区的推荐种植品种,采收时间以8月31日-9月4日为宜。研究结果将为合阳地区酿酒葡萄的种植示范和推广提供参考。
Red wine grape varieties'Cabernet Sauvignon''Cabernet Franc''Merlot''Pinor Noir'and'Marselan'were used as materials to investigate the changes of berry sugar,acid and sugar-acid ratio after veraison in Heyang county of Shaanxi.Polyphenols,tannins,anthocyanins and other quality indexes of mature berries were studied.The results showed that'Cabernet Sauvignon''Merlot'and'Marselan'had higher sugar content,whereas'Pinor Noir'and'Cabernet Franc'have lower sugar content.The total acid content were 5 g/L and the maturity coefficient were over 20 for all the 5 varieties.'Cabernet Sauvignon''Cabernet Franc'and'Marselan'had higher phenolic,anthocyanin and tannin contents.In general,'Cabernet Sauvignon''Merlot'and'Marselan'were appropriate to be the recommended planting varieties in Heyang.31th August to 4th September as harvest time were recommended.The results would provide a reference for the demonstration and promotion of wine grape cultivation in Heyang region.
