摘要

作物组成部分,如棚架系统,可能影响葡萄藤对太阳辐射的吸收,而其他组成部分,如砧木,可能影响接穗的活力。适当的管理提供了一个适宜的生殖和营养平衡,可以影响葡萄的化学成分。本研究旨在描述在巴西雨季和半干旱条件下,在不同的格架系统和砧木下种植的榨汁用“Isabel Precoce”葡萄的酚类成分和抗氧化活性。采用随机区组试验设计,采用时间分段试验设计,对2017年1 - 5月和2018年1 - 5月两种砧木(‘IAC 572’和‘IAC 766’)的架空、竖枝和竖枝定位系统进行了研究。格架系统、砧木、收获季节及其相互作用影响葡萄的性状。在季节中具有等效响应的处理确定了葡萄的具体特征。砧木‘IAC 766’为‘Isabel Precoce’葡萄提供了更大的串重和更低的酸度,而‘IAC 572’则产生了更高的可溶性固形物含量。在这两个季节中,在抗压性和多酚和花青素含量上,在高架葡萄架上种植的葡萄中变化较小。反过来,在2018年,通过ABTS●+方法,lyre的使用提供了高抗氧化活性。DPPH●法的抗氧化活性最高,是由于架空格架与IAC 766的关联。随着架空格架的使用,在季节中,等效的酚类化合物和抗氧化活性导致了均匀的质量。

Impact of trellis systems and rootstocks on global phenolic composition and antioxidant activity of ‘Isabel Precoce’ grapes produced during rainy seasons in semi-arid region of Brazil
Crop components, such as trellis systems, might affect solar radiation uptake by grapevines while others, such as rootstocks, influence the vigor of the scion. Proper management provides a suitable reproductive and vegetative balance that could influence the chemical composition of grapes. This study aimed to characterize the global phenolic composition and antioxidant activity of ‘Isabel Precoce’ grapes raised for juice, growing under different trellis systems and rootstocks, in rainy seasons, in semi-Arid conditions in Brazil. With a randomized block experimental design and split-split plots over time, the overhead trellis, lyre, and vertical shoot positioning systems and two rootstocks (‘IAC 572’ and ‘IAC 766’) in the harvest seasons of January-May, 2017 and January-May, 2018 were studied. Trellis systems, rootstocks, harvest seasons and their interactions affected the characteristics of the grapes. The treatments with equivalent responses in the seasons defined the specific characteristics of the grapes. The rootstock ‘IAC 766’ provided greater bunch weight and lower acidity to the ‘Isabel Precoce’ grapes, while ‘IAC 572’ induced higher soluble solids contents. In both seasons, there was lower variation in berry resistance to compression and polyphenol and anthocyanin contents in grapes from grapevines grown on an overhead trellis. In turn, the use of lyre provided high antioxidant activity by the ABTS●+ method in 2018. The highest antioxidant activity by the DPPH● method was due to the association of overhead trellis and ‘IAC 766’. With the use of the overhead trellis, equivalent phenolic compounds and antioxidant activity during the seasons resulted in a uniform quality.
