摘要
对2011年甘肃河西走廊张掖、武威、嘉峪关3个主要酿酒葡萄产地的栽培葡萄品种"梅鹿辄"(Merlot)、"赤霞珠"(Cabernet sauvignon)、"贵人香"(Italian riesling)和"蛇龙珠"(Cabernetgernischet)的果实品质进行了测定,利用主成分分析法得到标准化变量表达的主成分的表达式和相对应的方差贡献率构建预测模型,对河西走廊产区白色和红色品种进行了综合排序。结果表明:3个酿酒葡萄产地的"梅鹿辄"、"赤霞珠"、"贵人香"在还原糖、总酸、pH、总酚、单宁以及总花色素含量方面存在着显著的差异;张掖和武威2个地方的"蛇龙珠"在除总酸外的其它品质指标上差异显著;张掖地区的"蛇龙珠"和嘉峪关地区的"威代尔"综合评价最高,武威地区由于气象因素酿酒葡萄综合评价较低。
The quality of wine grapes （＇Merlot＇ ,＇ Cabernet sauvignon＇, ＇Italian riesling＇,＇ Cabernet gernischet＇） in three main planted regions （Zhangye,Wuwei,Jiayuguan） of Gansu Corridor Area were studied in this paper, and a predicted model was built with the principal component formulas expressed by standardized variables and the orresponding variance proportions through Principal Component Analysis （PCA） to rank synthetically the white and red wine grapes of Gansu Corridor Area. The results showed that ＇Merlot＇, ＇Cabernet sauvignon＇ and ＇Italian riesling＇ varied among three planted regions in the contents of reducing sugars, total acid, pH, total phenols, tannin and total anthocyanidins; ＇Cabernet gernischet＇ showed significant difference between Zhangye and Wuwei in all the quality indexes besides total acid; ＇Cabernet gernischet＇ in Zhangye and ＇Vidal＇ in Jiayuguan earned the highest general evaluation and wine grapes in Wuwei got low valuation due to meteorological factors.
