Abstract

: Vines are highly responsive to agricultural management techniques, such as training systems. Three training systems, i.e., conventional, high, and double training, for the ‘Niagara Rosada’ vine were studied considering aspects related to the yield, physicochemical, and antioxidant characteristics of the grapes. The experiment was carried out during two seasons (2017 and 2018), and the vines grafted on IAC 572 Jales. The training systems did not influence the fruit production per vine and yield of the ‘Niagara Rosada’ table grape, but some improvements were observed, such as a greater number of berries per bunch in vines managed in the conventional training systems and a higher fresh mass of berries when cultivated in the high and double training systems. Grapes from the double training system had higher soluble solids contents, an important sensorial characteristic in table grapes. The high training system, in turn, provided ‘Niagara Rosada’ table grapes with a greater content of bioactive compounds (e.g., phenolic compounds, flavonoids, and anthocyanins) and antioxidant activity.
培训系统改善了“尼亚加拉罗萨达”鲜食葡萄的农艺特性和品质
葡萄藤对农业管理技术(如培训系统)的反应非常灵敏。考虑到葡萄的产量、物理化学和抗氧化特性,研究了“尼亚加拉罗萨达”葡萄的三种训练系统,即常规训练、高训练和双重训练。实验分两个季节(2017年和2018年)进行,葡萄藤嫁接在IAC 572 Jales上。培训系统对“尼亚加拉罗萨达”鲜食葡萄的单株果实产量和产量没有影响,但观察到一些改进,例如在传统培训系统中管理的葡萄藤每串浆果数量更多,在高培训系统和双重培训系统中栽培的浆果新鲜质量更高。双重培养体系的葡萄具有较高的可溶性固形物含量,这是鲜食葡萄的重要感官特征。反过来,高训练系统为“尼亚加拉罗萨达”鲜食葡萄提供了更高含量的生物活性化合物(如酚类化合物、类黄酮和花青素)和抗氧化活性。
