In the Serra Gaúcha region, South Brazil, the occurrence of hail is common due to relief and the cold air currents coming from polar regions. Nowadays, the use of anti-hail nets to protect fruit production is increasing, but the real effects of using this coverture on vines are largely unknown. Thus, this work aimed to evaluate the impact of the use of an anti-hail net on the productivity and quality parameters of ‘Rose Niagara’ grapes grown in the region, in the 2019/2020 and 2020/2021 harvests. The studied parameters were production, number of bunches per plant, bunch length, berry diameter, mass of 100 berries, average bunch mass, juice pH, titratable acidity, soluble solids, phenolic compounds content, total anthocyanins content, and photosynthetically active radiation. The results showed that the anti-hail net influenced some quality parameters, but this change was not consistent in the two harvests, indicating a larger influence of edaphoclimatic conditions than of the use of the net. Thus, the anti-hail net may be an alternative to protect vineyards from hail and other bad weather conditions, without having important negative impacts on the production and quality of ‘Rose Niagara’ grapes.
Resumo
Na região da Serra Gaúcha, Sul do Brasil, é comum a ocorrência de granizo devido ao relevo e às correntes de ar frio que vêm das regiões polares. Atualmente vem crescendo o uso de telas antigranizo para proteger a produção frutícola, mas os reais efeitos do uso deste tipo de cobertura nas videiras são desconhecidos. Desta forma, o presente trabalho teve como objetivo avaliar o impacto do uso de tela antigranizo sobre a produtividade e os parâmetros de qualidade de uvas ‘Niágara Rosada’ cultivadas na região, nas vindimas de 2019/2020 e 2020/2021. Os parâmetros estudados foram a produção, o número de cachos por planta, o comprimento do cacho, o diâmetro dos bagos, a massa de 100 bagos, a massa média dos cachos, o pH do mosto, a acidez titulável, o teor de sólidos solúveis, o teor de compostos fenólicos, o teor de antocianinas totais e a intensidade de radiação fotossinteticamente ativa. Os resultados mostraram que a tela antigranizo influenciou alguns parâmetros de qualidade, mas estas alterações não foram consistentes nas duas vindimas, indicando uma maior influência das condições edafoclimáticas do que do uso da tela. Assim, a tela antigranizo pode ser uma alternativa para proteger os vinhedos do granizo e outras intempéries sem causar impactos negativos na produção e qualidade de uvas ‘Niágara Rosada’.
