Resumo: The El Niño-Southern Oscillation (ENSO) is a well-known source of interannual variability in the climate of Santana do Livramento, Campanha Gaúcha, Brazil. It affects the agronomic responses of several crops grown in the region. Analysis of a dataset comprising observations of grape yield and sugar content in 11 white and 17 red grape cultivars over the last 3 decades revealed some patterns. In the long term (several years or decades), yield and sugar content showed a negative relationship, that is, larger crop loads resulted in lower sugar content at harvest. However, a number of calculations and principal component analyses showed that annual yield and sugar content fluctuations in the short term can be better explained by considering as reference points only the results obtained for each crop one and two years before. Based on these simple calculations, there was a clear separation between El Niño and La Niña events. In the vineyards of this region, La Niña events typically tend to result in higher grape yields and sugar content at harvest, while the opposite is true for El Niño, which tend to produce lower grape yields and sugar content at harvest. The results of neutral events are typically closer to those of El Niño events.

A análise de um conjunto de dados que compreende observações de produtividade e teores de açúcar em uvas de videiras de 11 cultivares brancas e 17 cultivares tintas ao longo de quase 3 décadas revelou alguns padrões. No longo prazo (vários anos ou décadas), a produtividade e o teor de açúcar mostraram correlação negativa - maiores cargas de fruto resultaram em menores teores de açúcar na colheita. No entanto, alguns cálculos e análises de componentes principais permitiram definir que as oscilações da produtividade anual e do teor anual de açúcar no curto prazo podem ser melhor explicadas se for considerando apenas os resultados de um e dois anos anteriores de cada safra como pontos de referência. Seguindo esses cálculos, pôde-se notar uma clara separação entre eventos de El Niño e eventos de La Niña. Nos vinhedos desta região, os eventos de La Niña tipicamente tendem a resultar tanto em maior produtividade quanto em maior teor de açúcar na colheita. Em contraste, eventos de El Niño tipicamente tendem a causar menor produtividade e menor teor de açúcar na colheita. Anos neutros tipicamente apresentam resultados mais próximos aos eventos de El Niño.UEL2022-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4589910.5433/1679-0359.2022v43n5p2031Semina: Ciências Agrárias; Vol. 43 No. 5 (2022); 2031-2044Semina: Ciências Agrárias; v. 43 n. 5 (2022); 2031-20441679-03591676-546Xreponame:Semina.
