“…After the March-July/2017 cycle, the highest variation in SS content (18.1-20.4 ºBrix) was observed, although the rootstocks did not contribute to significant differences in TA (0.80-0.94 g tartaric acid 100 mL -1 ). Similar values for both variables were also observed in other studies for this cultivar (Yamamoto et al, 2012;Ejsmentewicz et al, 2015). These values are also close to those mentioned for other table grape cultivars (Moreira et al, 2012;Sonego et al, 2002).…”

“…As an example, Oliveira et al (2017) reported a SS content of 17.6 ºBrix. This value is indeed close to those (17-19 ºBrix) observed in other studies (Yamamoto et al, 2012;Ejsmentewicz et al, 2015). Regarding the TSS content, there were no significant differences ( Table 6).…”

“…'BRS Clara' and 'Arizul' grapes have presented medium to high productivity under tropical conditions and quality enough for fulfilling both national and international requirements for commercial trading. According to Yamamoto et al (2012), these cultivars presented agronomic and commercial characteristics for a profitable cultivation. However, technical adjustments are still required, particularly for 'Arizul' grapes, for which an efficient crop management under tropical conditions is unknown.…”

Quality and antioxidant potential of ‘BRS clara’ and ‘Arizul’ grapes influenced by rootstocks in a tropical region

Seedless table grapes cultivars have been studied in the Sub-middle region of São Francisco Valley at northeast Brazil. For that region, it is important to identify cultivars with productive potential, better quality and efficiency, minimizing the expenses in terms of inputs and workforce, when compared to traditional cultivars. Specifically, the objective of this study was to determine the influence of different rootstocks on the quality and on the antioxidant potential of BRS Clara and Arizul table grapes cultivars of two production cycles. The experimental area belongs to the Experimental Field of Bebedouro/Embrapa Semiárido, located in the sub-middle region of São Francisco Valley, in Petrolina - PE, northeast Brazil. Both BRS Clara and Arizul cultivars were analyzed individually using IAC 313, IAC 572, IAC 766, SO4, Paulsen 1103 and Harmony rootstocks, during production cycles from October/2016 to February/2017 and from March/2007 to June/2017. The experimental design was planned in randomized blocks, in a 2 (production cycle) x 6 (rootstock) factorial, with three replications each. More favorable conditions to quality for ‘BRS Clara’ grapes, as evidenced by higher berry mass, lower soluble solids (SS)/titratable acidity (TA) ratio and higher antioxidant activity, were observed after the March-June, 2017 harvest, especially from scions grafted onto IAC 572, SO4 and Harmony. The Arizul cultivar was characterized by better quality after the March-July, 2017 harvest, showing higher berry mass, lower acidity and lower SS/TA ratio and a better color mainly in SO4 and Harmony rootstocks. Therefore, an appropriate rootstock enhances the quality of the grapes.

Vineyard microclimate and yield under different plastic covers

et al. 2017

The use of plastic cover in vineyards minimizes effects of adverse weather conditions. The northwest of São Paulo State is one of the largest grape producing regions in Brazil; however, few studies investigate the effects of different plastic covers on vineyards in this region. This study compared the effect of black shading screen (BSS) and braided polypropylene film (BPF) on BRS Morena vineyard microclimate, grown on an overhead trellis system in the northwestern São Paulo. The experiments were carried out during three growing seasons (2012-2014). BSS allowed superior incoming solar radiation (SR) transmissivity, resulting in higher net radiation (Rn), and higher ratio between photosynthetically active (PAR) and SR. No differences were observed between the average air temperatures (T) and relative humidity (RH) of covered environments (BPF and BSS) and outside condition (automatic weather station-AWS), due to high air circulation, despite wind speed (WS) reduction caused by plastic covers. BPF provided better conditions for vineyard growth with higher fruit yield than vineyard under BSS regarding the number of shoots with bunches per plant, bunch and stem weights, longitudinal diameter of berries, quantity of fertile buds per shoot, and yield per shoot and per plant. BPF covers also influenced leaf size and growth speed of plants in vineyards.

“…Feldberg et al (2007), em Mocambinho-MG, constataram que, na média das cinco safras avaliadas para as videiras 'Crimson Seedless', o porta-enxerto 'Paulsen 1103' induziu ao aumento de 50,6% no número de cachos. Portanto, Yamamoto et al (2012) ressalta que a produção das videiras é influenciada por vários fatores, como: características da variedade e do portaenxerto, sistemas de condução, tipos de poda, fertilidade do solo, práticas culturais utilizadas em cada região e condições edafoclimáticas.…”

As variedades de uvas sem sementes apresentam maior dificuldades de adaptação às condições tropicais do semiárido nordestino, exibindo produções reduzidas e irregulares, resultado de sua baixa fertilidade de gemas, desgrane elevado e suscetibilidade à rachadura de bagas. O objetivo deste trabalho foi avaliar aspectos relacionados à susceptibilidade ao rachamento e podridão de bagas e características agronômicas de uvas sem sementes sob as condições do Submédio do Vale São Francisco. Para isso, o experimento foi conduzido no Campo Experimental de Bebedouro na Embrapa Semiárido, em Petrolina-PE. Foram avaliadas cinco variedades ao longo de dois ciclos de produção, correspondendo aos anos de 2013 e 2014. Utilizaram-se as variedades Adona, BRS Clara, BRS Maria Bonita, Arizul e Thompson Seedless, nas quais foram determinadas as seguintes variáveis: produção (Kg planta-1), número de cachos, massa do cacho (g); teor de sólidos solúveis (oBrix) e acidez titulável (g de ácido tartárico 100mL-1); bagas rachadas (%) e bagas podres (%). Os resultados mostraram que tanto o percentual de rachamento quanto o de podridão apontaram para as variedades BRS Clara e Adona como as mais tolerantes e a variedade Thompson Seedless como a mais suscetível. A maior produção por planta foi obtida no Ciclo 2 para a variedade BRS Clara (20,63 Kg planta-1), seguida da Adona (17,52 Kg planta-1. Assim, as variedades BRS clara e Adona destacaram-se com melhores características de qualidade e maior tolerância à rachadura e podridões de bagas, apresentando potencial para produção de duas safras ao ano no Submédio do Vale São Francisco.
