摘要

在温暖的地区,强迫葡萄藤再生和将果实成熟转移到生长季节较冷的部分可以增加红葡萄酒葡萄中总果实花青素(TFA)的浓度,但对花青素成分的影响尚不清楚。此外,据报道,改种后减少灌溉可以提高低降水的凉爽和温带地区的果实花青素,而这种反应以前没有在干燥和温暖地区种植的强迫葡萄中进行过研究。以赤霞珠(Cabernet Sauvignon, Vitis vinifera L.)为研究对象,在美国加州弗雷斯诺进行了连续两年的催熟试验,研究了催熟期对赤霞珠果实花色苷含量和成分的影响,以及催熟后减少灌溉对催熟葡萄果实花色苷含量的影响。采用常规方法(非强制)的葡萄藤作为对照。强制处理包括在6月中旬去除初生叶、丛枝和侧枝,并对初生芽进行套篱。对照葡萄藤按作物蒸散量(ETC)的80%灌溉,而强迫葡萄藤按作物蒸散量(ETC)的40%、60%、80%或100%灌溉。结果表明,在两年多的时间里,强迫葡萄藤再生和推迟果实成熟导致TFA(主要是非酰化花青素)在果实成熟和收获期间显著增加。强制处理也改变了收获时果实花青素的组成,由飞燕草苷和矮牵牛花苷的糖苷组成的TFA比例增加,而malvidin糖苷的比例降低。这项研究表明,强迫葡萄藤再生和在温暖地区转移果实成熟可以导致果实花青素的更平衡的轮廓,具有改进的非酰化衍生物和改变五种花青素苷的相对丰度。然而,改型后减少灌溉对强迫葡萄果实花青素的影响很小。

Improving fruit anthocyanins in 'Cabernet Sauvignon' by shifting fruit ripening and irrigation reduction post veraison in warmer region
In warmer regions, forcing vines to regrow and shifting fruit ripening to the cooler portion of the growing season can increase the concentration of total fruit anthocyanins (TFA) in red winegrapes, but the effect on anthocyanin composition remains unclear. Additionally, irrigation reduction post veraison was reported to improve fruit anthocyanins in cool and temperate regions with low precipitation, whereas this response has not been previously examined in forced vines grown in dry and warm regions. Experiments were conducted with 'Cabernet Sauvignon' (Vitis vinifera L.) over two consecutive years in Fresno, California, to investigate the effect of shifting fruit ripening on the concentration and composition of fruit anthocyanins as well as the influence of post-veraison irrigation reduction on fruit anthocyanins of forced vines. Vines under conventional practices (non-forced) were used as the control. Forcing treatment included removing primary leaves, clusters, and laterals, as well as hedging primary shoots, in mid-June. Control vines were irrigated at 80 % crop evapotranspiration (ETC) post veraison, whereas forced vines were irrigated at 40, 60, 80, or 100 % ETC post veraison. Results suggest that forcing vines to regrow and shifting fruit ripening led to a significant increase of TFA, primarily non-acylated anthocyanins, during fruit ripening and at harvest over two years. Forcing treatment also altered composition of fruit anthocyanins at harvest, with increased proportions of TFA comprised by the glucosides of delphinidin and petunidin but the decreased proportion of the glucosides of malvidin. This study demonstrates that forcing vines to regrow and shifting fruit ripening in the warmer region can lead to a more balanced profile of fruit anthocyanins, with improved non-acylated derivatives and altered relative abundance of the glucosides of five anthocyanidins. Reducing irrigation post veraison, however, had only a minor effect on fruit anthocyanins in forced vines.
