“…The grapevines grafted on 'IAC 766' had heavier clusters than those on 'IAC 572' (Table 6) and are in agreement with the results obtained by Silva et al (2018) in 'Isabel Precoce','BRS Carmem','BRS Cora', Máximo', which also exhibited heavier clusters on IAC 766. The 'BRS Magna' clusters exhibited a mean of 165 g when grafted onto the IAC 766 rootstock, near the values obtained by Leão et al (2018) in previous studies with the same cultivar in the Vale do Submédio São Francisco.…”

“…The Vale do Submédio São Francisco stands out as the new emergent production region of high-quality grape juices produced from Brazilian cultivars, such as 'Isabel Precoce', 'BRS Magna', 'BRS Violeta', 'BRS Cora', and 'BRS Carmem' (Lima et al, 2014). The BRS Magna has yielded prodigiously in the Vale do Submédio São Francisco (Leão et al, 2018) and is rich in phenolic compounds and antioxidant activity (Lima et al, 2014).…”

Over the past decade, the business of producing juice from grapes (Vitis labrusca L. and hybrids) has been expanding in response to increasing consumption encouraged by campaigns promoting the benefits grape juice can have on health. This study aimed to determine the effect of the production cycle, vine training system, and rootstock on the yield and physical and physical-chemical characteristics of 'BRS Magna' grapes grown in the Vale do Submédio São Francisco in the northeastern region of Brazil. The study was conducted in Petrolina, Pernambuco, over eight production cycles (2017 to 2020). The grapevines were trained in three vine training trellis systems: espalier, lyre, and pergola; and grafted onto two rootstocks: IAC 572 and IAC 766. The production cycle, training system, and rootstocks affected the yield components, vigor, and physical characteristics of the BRS Magna grapes. The combination of the pergola training system and rootstock IAC 766 stood out from the others, providing mean yields estimated at 26 t ha -1 per production cycle. The soluble solids content (SS), titratable acidity (TA), and SS TA -1 ratio were affected neither by the training system nor the rootstock, and higher values for SS and lower values for TA were obtained in the first, second, fourth and eighth production cycles. Thus, the pergola training system and rootstock IAC 766 are recommended for promoting yield gains in the 'BRS Magna' grape in the Vale do Submédio São Francisco.

“…Therefore, the lower average values of temperatures and global radiation might have reduced the metabolism in berries harvest in the first half of 2018. Leão et al (2018), studying the same region and with the same cultivar trained to overhead trellis and grafted onto 'IAC 572', reported soluble solid contents of 17.5 ºBrix, and observed no influence of production cycle.…”

“…Some studies have highlighted characteristics in juices made from 'BRS Magna' grapes, including basic components of quality, phenolic profile and contents, antioxidant activity and volatile organic compounds (Crucello et al, 2018;Lima et al, 2014;Mariani;Nava, 2018;Ristchel et al, 2014). Aspects of phenology, adaptation to different regions and yield performance have also been evaluated (Ritschel et al, 2014;Leão at al., 2018). Additionally, the cultivated areas are expanding despite the limited knowledge on management techniques, including production factors that provide higher agronomic performance.…”

The Submedium São Francisco Valley is renowned for its particular conditions for cultivating grapes for different uses. The production of grapes for juice is relatively recent, and thus, knowledge is still limited on components of the production system. The aim of this study was to characterize the quality and antioxidant activity of ‘BRS Magna’ grapes in irrigated crops of the Submedium São Francisco River Valley under the influence of training systems and rootstocks, in production cycles of the first half of the year. The experiment was conducted in the Experimental Field of Bebedouro/Embrapa Semiárido, in Petrolina, Pernambuco, Brazil. The following were studied: overhead trellis, lyre, and vertical shoot positioning (VSP) systems and rootstocks ‘IAC 572’ and ‘IAC 766’, in the production cycles corresponding to the first halves of 2017 and 2018. Experimental design was in randomized blocks, with sub-subplots through time and four replicates. Overall, responses depended on training systems, rootstocks, and production cycles, which determined specific traits of the grapes. Production in the first half of 2018 was characterized by high anthocyanin contents, high total extractable polyphenols, and higher antioxidant activity, and responses were differentiated according to training system and rootstock. Plants trained to overhead trellis and grafted on ‘IAC 572’ had higher accumulation of total extractable polyphenols and antioxidant activity in berries. Plants trained to VSP had increased sugar, yellow flavonoid, and anthocyanin contents in berries while lyre training system led to higher bunch mass.

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.
