- 摘要:
- 以山葡萄新品种‘北国蓝’果实为试材，对各采收期的果实及其原酒的理化指标进行测定，研究不同采收期对果实品质及其酒质的影响。结果表明:不同采收期对‘北国蓝’的果实品质有明显影响，随着采收期的延迟果粒直径、平均粒重、平均穗重、出酒率、总糖含量均呈先升高后降低的趋势；果实总酚、单宁含量持续增加，较第一次采收分别增加了27.94%和92.50%；滴定酸含量无规律性变化，但10月5日含量最低(18.27 g/L)，各不同采收期差异显著。不同采收期果实酿造的葡萄酒滴定酸含量与果实滴定酸含量呈极显著正相关；葡萄酒总酚和单宁含量与果实总酚和单宁含量均呈显著正相关。果实品质和酿酒特性分析表明，‘北国蓝’在当地最佳采收时期为9月30日至10月5日。
- Abstract:
- Taking the berries of new cultivar of Vitis amurensis Rupr.‘Beiguo Lan’ as materials，and physicochemical indexes on grape fruit and wine of different harvest time were measured in order to research the influence of different harvest time on fruit quality and oenological characteristics.The results showed that，firstly，different harvest time had significant influence on fruit quality of ‘Beiguo Lan’.The single berry diameter，average weight of grain，average weight of ear，liquor yield，and the content of total sugar all increased firstly and then decreased with the delaying of harvest time.The content of total phenols and tannin increased continuously，finally increased by 27.94% and 92.50% respectively compared with the first time of harvest.The content of titrable acids had not regular changes，yet reached the minimum value (18.27 g/L) on the 5th，Oct.and its existed significant difference in different harvest time.Secondly，the content of titrable acids had highly significantly positive correlation between fruit and wine brewed by berries harvested in different harvest time.There was significantly positive correlation on the content of total phenols and tannin in fruit and wine.The analysis results of the fruit quality and oenological characteristics showed that the best harvest period of the ‘Beiguo Lan’ was between 30th，Sep.and 5th，Oct.in the local.
