摘要:

对2013年陕西渭北地区的14 个鲜食葡萄品种的17 项生物经济学指标进行观察测定,并运用模糊数学和聚类分析评价了不同葡萄品种果实的综合品质。结果表明:品种间果实的果粒形状、产量、花色苷含量、果粉厚度、果皮厚度和果皮颜色性状变异系数较大,而果实感官品质和内在品质相关指标的变异系数较小。模糊数学评价筛选出综合品质较好的品种为红地球、夏黑、红宝石、8611、金田0601和魏可,而秦龙大穗、弗雷无核的综合品质较差。聚类分析结果表明,品质优等的8611、红地球、红宝石和魏可聚为一类,为优良的鲜食葡萄栽培种,品质中等的玫瑰香、巨玫瑰和红乳聚为一类,而品质最差的弗雷无核单独聚为一类。模糊数学评价方法结合聚类分析可给予葡萄综合品质较全面、客观的评价。

Abstract:

Fuzzy mathematics and cluster analysis were used for comprehensive quality assessment of fourteen table grape
varieties sampled from a commercial vineyard in Weinan, Shannxi province in 2013. The results showed that there were
larger coefficients of variation in berry shape, yield, total anthocyanin content, berry skin thickness, berry bloom thickness,
and berry color characteristics, whereas sensory properties and related indicators of intrinsic quality were relatively
lower. The comprehensive assessment by fuzzy mathematics analysis showed that “Red Globe”, “Summer Black”, “Ruby
Seedless”, “Wuhengzaohong” ,“Jintian 0601” and “Wink” had superior quality. “Qinlongdasui” and “Flame Seedless”
showed the lowest quality. By using Q-type cluster analysis, “Wuhengzaohong”, “Red Globe”, “Ruby Seedless” and “Wink”
with superior quality were clustered into one group, “Muscat Hamburg”, “Jumeigui” and “Hong Ru” with average quality
were assigned into another group, and “Flame Seedless” with the worst quality was clustered into a separate category. The
combination of fuzzy mathematics and cluster analysis could provide a comprehensive and objective evaluation system for
determining the quality of grape varieties.

Key words: grape varieties, comprehensive quality, fuzzy mathematics, cluster analysis
