山东平度爱迪尔酒庄主要酿酒葡萄品种的研究

Study on the Major Grape Varieties in Pingdu Ideal Winery

针对我国葡萄酒产区存在同质化的问题,以山东平度爱迪尔酒庄酿酒葡萄品种"宝石"(‘Cabernet Ruby’)、"梅鹿辄"(‘Merlot’)和"贵人香"(‘Italian Riesling’)为试材,研究了各品种的物候期、病害、成熟进程及成熟果实的主要品质指标,以期发掘该区域内特色优势酿酒葡萄品种。结果表明:"贵人香"和"宝石"的叶片发病率较轻,"梅鹿辄"发病最重,3个品种果粒发病率无明显差异,但"梅鹿辄"的果穗发病率显著高于"宝石"和"贵人香";供试品种在当地均未达到最佳成熟期,"梅鹿辄"、"宝石"和"贵人香"分别于2012年9月8日、18日和20日采收,采收时"贵人香"的成熟度最好,但果实还原糖含量均低于180mg/L;"贵人香"果实总酚及单宁含量均极显著(P<0.01)低于2个红色品种,同时"梅鹿辄"果实单宁含量显著(P<0.05)低于"宝石",而"宝石"果实总花色苷极显著(P<0.01)高于"梅鹿辄"。整体而言,"贵人香"在该地区的表现最佳,具有较好的发展潜力。

Due to the existing problem of homogenization in Chinese wine regions,the phenophase,grape diseases conditions,ripening process,the main quality indexes in maturity fruit of the main wine grape varieties（＇Cabernet Ruby＇,＇Merlot＇,＇Italian Riesling＇） during the maturation were studied at Ideal Winery in Pingdu county in order to explore the characteristic and preponderant wine grape varieties.The results showed that the lighter diseases incidence in the leaves of ＇Italian Riesling＇ and ＇Cabernet Ruby＇ while the worse in ＇Merlot＇,no significant difference in berry disease incidence,but ＇Merlot＇ was significantly higher than ＇Cabernet Ruby＇ and ＇Italian Riesling＇ in cluster diseases incidence.＇Merlot＇,＇Cabernet Ruby＇ and ＇Italian Riesling＇ were harvested on September 8th,18th and 20th in 2012 while they all failed to reach their optimum maturity,＇Italian Riesling＇ had the best maturity among tested varieties,but the reducing sugar contents of all varieties were lower than 180 g/L;the content of total phenols and tannin in ＇Italian Riesling＇ was lower than red varieties,and showed very significant difference（P〈0.01）.The content of tannin in ＇Merlot＇ was significantly（P〈0.05） lower than ＇Cabernet Ruby＇,and the content of anthocyanins in ＇Cabernet Ruby＇ showed very significant（P〈0.01） higher than ＇Merlot＇.Overall,＇Italian Riesling＇ performed better than other tested grape varieties in this area,this result showed that ＇Italian Riesling＇ will have a good development as a potential wine grape variety.
