Abstract

The quality and phenolic compound composition might be affected by production system due to microclimate around the bunches and sunlight interception provided by vegetative canopy architecture and environmental conditions. The aim of this study was to characterize the quality and antioxidant potential of ?BRS Cora? grapes with different trellis systems and rootstocks in rainy seasons under tropical conditions. Three trellis systems and two rootstocks were studied in production cycles during the first halves of 2017 and 2018, using a randomized-block experimental design. Interactions between the trellis systems, rootstocks and cycles differentially affect the fruit quality. The association between vertical shoot positioning or an overhead trellis with ?IAC 766? induced higher polyphenol compound contents. In turn, the trellis systems overhead trellis and lyre provided greater stability for the berry weight, soluble solids, total soluble sugar contents, yellow flavonoids, total extractable polyphenol compounds or antioxidant activity in both production cycles. The results of this study inferred that the grape quality and phenolic compound composition were not only affected by some specific climatic factors but also by the trellis system, rootstock, and the interaction between the three factors.

在半干旱的雨季条件下,格架系统和砧木对‘BRS Cora’葡萄的品质和抗氧化潜力有影响
由于束周围的小气候、植被冠层结构和环境条件的遮光作用等因素,生产系统可能会影响其品质和酚类化合物的组成。本研究的目的是表征?BRS Cora?的质量和抗氧化潜力。热带雨季不同格架系统和砧木的葡萄。采用随机区组试验设计,在2017年上半年和2018年上半年的生产周期中研究了三种格架系统和两种砧木。格架系统、砧木和周期之间的相互作用对果实品质有不同的影响。垂直拍摄定位或架空格架与IAC 766之间的关系?诱导较高的多酚化合物含量。反过来,在两个生产周期中,格架和琴架系统在浆果重量、可溶性固形物、总可溶性糖含量、黄酮类化合物、总可提取多酚化合物或抗氧化活性方面提供了更大的稳定性。本研究结果表明,葡萄品质和酚类化合物组成不仅受某些特定气候因素的影响,还受格架制度、砧木以及三者之间的相互作用的影响。
