“…By evaluating the influence of pruning season on the cv. Niagara Branca, Souza and Fochesato (2007) reported that pruning in early November, enabled a second harvest in March or April. For these authors summer pruning is an alternative to increase the supply of grapes, without affecting their quantity and quality from first harvest.…”

The current study aimed to evaluate the effect of different rootstocks (‘IAC 766’, ‘IAC 572’, ‘IAC 313’, ‘IAC 571-6’ and ‘106-8 Mgt’) on the physicochemical quality of ‘Niagara Rosada’ grape under Brazilian subtropical climate. In this study, a vineyard trellising system supported three years old vines at a density of 6536 plants ha-1. Therefore, evaluations consisted of three pruning seasons: two winter pruning (August 2011 and September 2012) and a summer pruning (January 2012). A complete randomized block design was conducted, subdivided into plots, with five replicates, the plots represented by 5 rootstocks and subplots by pruning seasons. We evaluated bunch number per plant; bunch, berry and rachis fresh mass; berries number per bunch; soluble solid, pH and titratable acidity content in the grape must. Results showed that ‘Niagara Rosada’ grafted onto ‘IAC 572’, presented the highest bunch mass (227g), rachis fresh mass (7.5g) and berries number per bunch (66); while ‘IAC 313’ rootstock performed the lowest values. Moreover, ‘IAC 766’ and ‘106-8 Mgt’ rootstocks presented the highest soluble solid and titratable acidity content, due to these rootstock’s precocity. Furthermore, the highest ratio between soluble solid and titratable acidity was found in ‘Niagara Rosada’ grafted onto ‘IAC 313’ and ‘IAC 571-6’ rootstock.

“…However, there is no known information in the literature about the nutrient content and the extraction of 'Niagara Rosada' grapevine considering this pruning modality, especially when different rootstocks are used. In Brazil, good results were obtained by Abrahão et al (2002) in the state of Minas Gerais, Souza & Fochesato (2007) in the state of Rio Grande do Sul, and Hernandes et al (2013) in the state of São Paulo, when summer pruning was adopted for the Niagara Rosada and Niagara Branca cultivars, which allowed a second harvest from March to May, representing an alternative to expand the product-offering period.…”

The objective of this work was to evaluate the influence of rootstocks and pruning times on yield and on nutrient content and extraction by pruned branches and harvested bunches of 'Niagara Rosada' grapevine in subtropical climate. The rootstocks 'IAC 766', 'IAC 572', 'IAC 313', 'IAC 571-6', and '106-8 Mgt' were evaluated. Treatments consisted of a combination between five rootstocks and three pruning times. At pruning, fresh and dry matter mass of branches were evaluated to estimate biomass accumulation. At harvest, yield was estimated by weighing of bunches per plant. Branches and bunches were sampled at pruning and at harvest, respectively, for nutrient content analysis. Nutrient content and dry matter mass of branches and bunches were used to estimate total nutrient extraction. 'Niagara Rosada' grapevine grafted onto the 'IAC 572' rootstock had the highest yield and dry matter mass of bunches, which were significantly different from the ones observed in 'Niagara Rosada'/'IAC 313'. 'Niagara Rosada' grafted onto the 'IAC 572' rootstock extracted the largest quantity of K, P, Mg, S, Cu, and Fe, differing from 'IAC 313' and 'IAC 766' in K and P extraction, and from '106-8 Mgt' in Mg and S extraction. Winter pruning results in higher yield, dry matter accumulation by branches, and total nutrient content and extraction.

“…Dessa forma, alternativas que visem alterar o perfil da viticultura no Rio Grande do Sul provocando mudanças na estrutura de oferta e, conseqüentemente, do mercado interno deste produto, podem trazer vantagens econômicas ao viticultor e de disponibilidade da fruta ao consumidor (SOUZA e FOCHESATO, 2007). Alterações na estrutura de produção, mediante colheitas antecipadas e/ou tardias de uvas de mesa, Vitis labrusca ou Vitis vinifera, por meio do manejo da poda, configuraria um cenário mercadológico distinto ao apresentado atualmente pelo Estado (MANFROI et al, 1996).…”

RESUMOO manejo adequado da poda permite alterar a fenologia da videira, modificando os períodos de colheita, inclusive com potencial de obtenção de mais de uma safra por ciclo vegetativo. Diante desse potencial avaliou-se uma época de poda seca no inverno (08/08/05) e duas épocas de poda verde (04/11/05 e 02/12/05) nas cultivares Niagara Branca e Concord, ambas Vitis labrusca, visando obter duas safras no mesmo ciclo vegetativo. O experimento foi realizado na safra 2005/2006 em videiras cultivadas em sistema de espaldeira, localizadas em Eldorado do Sul -RS. Variáveis associadas à fenologia, produção por planta, peso dos cachos, sólidos solúveis totais (SST), acidez total titulável (ATT) e relação SST/ATT foram analisadas para as safras obtidas. O ciclo fenológico das plantas podadas no inverno foi de 156 dias para a 'Niagara Branca' e 161 dias para a 'Concord', com colheita realizada em meados de janeiro. Por sua vez, o ciclo fenológico das brotações oriundas das podas verdes realizadas em 04/11/2005 e 02/12/2005 foi, respectivamente, de 127 e 113 dias, para a 'Niagara Branca', e 134 e 120 dias para a 'Concord', com colheitas realizadas em meados do mês de abril. A época de poda verde realizada em 04/11/05 permitiu maior produção por planta e cachos de maior peso, independentemente da cultivar, comparativamente à 02/12/05. A qualidade dos frutos foi semelhante entre as safras, mostrando apenas diferenças significativas entre cultivares, expressa numa menor ATT e maior relação SST/ATT para a 'Niagara Branca'.Palavras-chave: Vitis labrusca; fenologia; manejo da poda; segunda colheita. ABSTRACTThe adequate pruning management of grapevine permits to change its fenology, modifying the crop periods and creating conditions for two annual harvests. A winter pruning period (08/08/05) and two periods of summer pruning (04/11/ 05 and 02/12/05) were evaluated in order to obtain two annual harvests, using Niagara Branca and Concord grape varieties (both Vitis labrusca). This experiment was performed during the 2005/2006 season in grapevines conducted by cordon training in Eldorado do Sul county, Rio Grande do Sul, Brazil. Variables associated to fenology, plant production, weight of grapes, total soluble solids, total titratable acidity and ratio total soluble solids by total titratable acidity related to harvests were analyzed. The fenology of plants pruned in winter was 156 days for 'Niagara Branca' and 161 days for 'Concord', and the harvest was performed around January, 15th. Regarding the summer pruning performed on 04/11/05 and 02/12/05, fenology cycle of shoots was 127 and 113 days for the 'Niagara Branca' and 134 and 120 days for the 'Concord', respectively. Harvest was realized in middle April, 15th. The summer pruning realized in 04/11/05 provided higher production per plant and grapes of higher weight, independent of cultivar, when compared to the 02/12/05 pruning. Fruit quality was similar among the harvests, with significant differences between cultivars expressed by smaller total titratable acidity and higher ...
