“…The concentration of sugars in grape berries affects their sensory properties, since sugars can generate precursors for the synthesis of organic acids and phenolic and aromatic compounds during ripening (Kuhn et al 2013). In grape must, the SS content ranged from 17.9 to 18.6 °Bx, which is in accordance with the commercial standard, thus corroborating the literature on 'Sauvignon Blanc' (Würz et al 2019).…”

In viticulture, training systems and rootstocks are crucial factors in the growth and development of plants, thus affecting the production and quality of grapes. Therefore, the present study aimed to determine the best combination of rootstock and training system for 'Sauvignon Blanc', in Jundiaí, state of São Paulo, Brazil. To assess the data, a randomized block design in a 2 × 2 factorial scheme was used, that is, two rootstocks ('IAC 766 Campinas' and '106-8 Mgt') and two training systems (low and high espaliers), with four replications. The characteristics assessed were production, physicochemical analysis and concentration of bioactive compounds. With regard to the physicochemical composition of the grape must, the results indicated that the tested combinations are within the standard requirements for the winemaking industry; outcomes may change according to the rootstock used, i.e., an increase in production or an increase in the nutritional quality of the fruits. Nevertheless, '106-8 Mgt' rootstock showed great yield in both training systems, that is, an increase of up to 80%. Finally, 'Sauvignon Blanc' must be grafted on to 'IAC 766 Campinas' rootstock through a low espalier system to achieve a high content of phenolic compounds and flavonoids, and high antioxidant activity.

“…The most widely applied systems in Brazil are lyre (Y or V), VSP, GDC, and pergola systems. Papers in the literature have evaluated Y-trellis and VSP systems in the control of downy mildew and botrytis bunch rot diseases in a high-altitude region in Santa Catarina (south of Brazil) [ 12 ], the effects of VSP and Y systems on Cabernet Sauvignon grape berry ripening [ 13 ], and the agronomic performance and chemical composition differences associated with GDC, pergola, simple curtain, and VSP systems [ 14 ].…”

The grapevine is a climbing plant and allows for the manipulation of vegetative canopies to change the microclimate and exposure of leaves and clusters to solar radiation, affecting the primary and secondary metabolisms of plants. Thus, this work aimed to evaluate how the lyre and Geneva double-curtain (GDC) training systems could contribute to the volatile composition of sparkling wines in replicates of vinifications carried out in the Serra da Mantiqueira (Brazil) in two consecutive summer harvests (2017 and 2018). Fifty-four free volatile compounds were identified by HS-SPME/GC-MS in the wines in both systems and vintages. Multivariate analysis differentiated the vintages in component 1 (22.7%) and the training systems in component 2 (7.1%). The crops were differentiated by aldehydes in 2017 and in 2018 by isoamyl acetate ester, probably derived from the amino acid leucine, the season having been more humid, with lower temperatures and less radiation. For the training systems, besides the alcohol compounds, the GDC was differentiated by the terpenoid compounds geranylacetone and β-damascenone, which may contribute more pleasant aromas to sparkling wines. This work promotes additional research and enables winegrowers, through the management of their vineyards, to achieve sparkling wines with different volatile compositions.

“…The grapevine has a great diversity of architecture in its canopy and perennial parts, constituting different training systems (Wurz et al, 2019). To overcome the problem of excessive vigor, changing the shape of the canopy can be an alternative to achieve a balance between vegetative growth and production.…”

“…Besides influencing the plant ecophysiology (Favero et al, 2010), the training systems can affect vineyard productivity (Hernandes et al, 2013;Pedro Junior et al, 2015;Wurz et al, 2019), grape quality (Palliotti, 2012;Wurz et al, 2019), wine sensory properties and phenolic characteristics (Fragasso et al, 2012), and diseases epidemiology (Bem et al, 2016;Bem et al, 2017).…”

The objective of the present work was to compare the effect of the training systems Y-trellis (Y) and Vertical Shoot Position trellis (VSP) on the production efficiency and chemical characteristics of grapes and wine from ‘Sauvignon Blanc’ cultivated in high altitude regions of Santa Catarina State, Brazil. The study was carried out in 2013, 2014 and 2015 harvests in a commercial vineyard located in the municipality of São Joaquim - SC (28º 17 ’38 ”S and 49º 55’54” O, altitude 1350 m). The obtained data were subjected to analysis of variance (ANOVA) with F Test (p ≤ 0.05). The relationship between the vegetative growth and the yield was influenced by the training system. For the ‘Sauvignon Blanc’ cultivar, the yield was 93% higher in the Y-trellis training system, resulting in better vegetative-productive balance. The technological and phenolic maturation of the grapes were similar in both training systems. The results of this study show that the Y-trellis training system is an alternative to use in Santa Catarina altitude regions because it provides an increased productivity on the ‘Sauvignon Blanc’ variety without compromising the composition of grapes, when comparing to the VSP training system.
