Several studies have reported the influence of rootstocks on grape and wine composition, however, there is considerable variability in the results. The objective of this work was to evaluate the effects of three different rootstocks on vegetative-productive balance and the wine composition of ‘Merlot’. The present work was conducted in the municipality of Painel, during the 2014/2015, 2015/2016 and 2016/2017 vintages. The vegetative, productive, and enological variables of ‘Merlot’ grafted onto ‘Paulsen 1103’, ‘3309 Couderc’ and ‘101-14 Mgt’ rootstocks were evaluated. The ANOVA results showed that‘3309C’ rootstock promoted an increase in the productive indices, and consequently in more adequate vegetative-productive balance for ‘Merlot’ variety compared to the rootstocks ‘Paulsen 1103’ and ‘101-14 Mgt’. The rootstocks ‘3309C’ and ‘101-14 Mgt’ provided more adequate maturation indices for ‘Merlot’. The ‘101-14 Mgt’ rootstock was associated with the highest contents of flavonoid compounds, while the ‘3309C’ rootstock was related to higher contents of non-flavonoid compounds, especially resveratrol.
Resumo
Vários estudos têm relatado a influência dos porta-enxertos na composição da uva e do vinho, mas existe uma variabilidade considerável nos resultados. O objetivo deste trabalho foi avaliar o efeito de diferentes porta-enxertos sobre o equilíbrio vegeto produtivo e a composição dos vinhos da variedade ‘Merlot’. O presente trabalho foi conduzido no município de Painel, durante os ciclos 2014/2015, 2015/2016 e 2016/2017. Foram avaliadas as variáveis vegetativas, produtivas e enológicas da variedade ‘Merlot’ enxertada sobre ‘Paulsen 1103’, ‘3309 Couderc’ e ‘101-14 Mgt’. Os resultados da ANOVA revelaram que o porta-enxerto ‘3309C’ promoveu um incremento dos índices produtivos e, consequentemente, índices de equilíbrio vegeto-produtivos mais adequados para a variedade ‘Merlot’ em comparação com os porta-enxertos ‘Paulsen 1103’ e ‘101-14 Mgt’. Os porta-enxertos ‘3309C’ e ‘101-14 Mgt’ propiciaram uma maturação mais adequada da variedade ‘Merlot’. O porta-enxerto ‘101-14 Mgt’ esteve associado a teores mais elevados de compostos flavonóides, enquanto o portaenxerto ‘3309C’ esteve relacionado com teores superiores de compostos não-flavonóides, com destaque para o resveratrol.
