“…In a previous study evaluating botrytis bunch rot in two training systems (VSP and Y) with 'Sauvignon Blanc', Bem et al (2017) observed higher compactness in clusters produced in Y-trellis, which also resulted in higher incidence and severity of botrytis bunch rot. The Y-trellis tends to reduce vine vigor, leading to a better balance between vegetative growth and production (Reynolds and Vanden Heuvel, 2009); however, due to the higher nutrient flow to the berries, there is also an increase in cluster compactness (Hernandes et al, 2013).…”

“…The cluster compactness index is considered an important factor to assess grape quality (Tello and Ibáñez, 2014). This condition can make plants more susceptible to fungal diseases, especially Botrytis cinerea (Evers et al, 2010;Bem et al, 2017).…”

“…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.

“…De acordo com Molitor et al (2012), Molitor et al (2014) e Bem et al (2017), medidas culturais que resultam em maior exposição solar e ventilação na região dos cachos, como o manejo da desfolha, são ferramentas eficientes nas estratégias de controle da B. cinerea nos cachos da videira. E em plantas submetidas a elevadas cargas de gemas planta -1 , deve-se realizar essas medidas culturais, como a desfolha no estádio baga chumbinho, proporcionando maio eficiência no controle da doença (Wurz et al, 2017b;Wurz et al, 2020b).…”

O aumento do dossel vegetativo e o adensamento de cachos na planta ocasionado pelo maior número de gemas planta-1 pode criar um microclima favorável para a ocorrência de podridão cinzenta. O presente trabalho teve como objetivo avaliar o efeito do aumento de carga de gemas planta-1, nas variáveis epidemiológicas de podridão cinzenta (Botrytis cinerea) na videira Cabernet Franc cultivada em região de altitude de Santa Catarina. O presente trabalho foi conduzido durante safra 2016/2017, em um vinhedo comercial, localizado no munícipio de São Joaquim. Os tratamentos consistiram em quatro diferentes níveis de poda: 15 gemas planta-1, 30 gemas planta-1, 50 gemas planta-1, 75 gemas planta-1. Avaliou-se: incidência máxima, severidade máxima, AACPID, AACPSD, TAMID, TAMSD e IAS. Observou-se efeito da carga de gemas planta-1 nas variáveis epidemiológicas da podridão cinzenta nos cachos da videira Cabernet Franc. O aumento da carga de gemas resultou em aumento da incidência e da severidade da doença, AACPID e AACPSD, sendo os maiores observados em plantas submetidas a poda de inverno com carga de gemas superiores a 50 gemas planta-1. A adoção de elevado número de gemas planta-1, deve ser acompanhada de práticas de manejo integrado de doenças que visam reduzir os efeitos ocasionados pela ocorrência de podridão cinzenta.

Changes in vineyard productive attributes and phytochemical composition of sauvignon blanc grape and wine induced by the application of silicon and calcium

BACKGROUND: It is important to increase productivity and improve plant quality at the same time as preserving the principles of safety and productivity. The present study aimed to evaluate the effects of different concentrations of sodium metasilicate and calcium chloride, applied as fertilizers, on the productivity and phytochemical characteristics of Sauvignon Blanc grapes and their respective wines. RESULTS:The experiments were conducted using 2017 and 2018 vintages of commercial Sauvignon Blanc grapes. The treatments consisted of applying separately different concentrations of sodium metasilicate (0, 4, 8 and 12 g L −1 ) or calcium chloride (0, 5, 10 and 15 g L −1 ). The treatments were carried out during four phenological phases. The grapes were harvested at technical maturity and white wines were elaborated. The application of inorganic salts, silicon and calcium to the grapes had a significant effect on the vineyard productivity. The best results were obtained with 4 and 8 g L −1 silicon and 15 g L −1 calcium. An increase in the concentration of phenolics in the grapes was noted. These compounds have antioxidant capacity, which is one of the factors responsible for the resistance of the grapes to pathogens. CONCLUSION: The application of 4 and 8 g L −1 silicon and 15 g L −1 calcium to the grapes represents a potential alternative fertilizing strategy, which could increase the plant yield without damaging the phytochemical characteristics of the fruit and its derivatives.
