“…The antioxidant activity of the P. physalis plant extracts is attributed to their bioactive compounds, mostly phenolics, because of their ability to scavenge free radicals (Casanova et al, 2008, Saito et al, 2008. Similarly, Rodrigues et al (2011) confirmed that the blueberry (Vaccinium sp.) produced in Brazil is a good source of phenolic compounds, has high antioxidant activity.…”

“…Resultado que está de acordo com o observado por Rodrigues et al (2011), que avaliaram o teor de compostos fenólicos e o potencial antioxidante de diferentes cultivares de mirtilo e observaram que a cultivar Powderblue apresentou maior teor de antocianinas que a cultivar Bluegem. A cor dos frutos está associada a atributos genéticos, mas também à radiação solar incidente sobre eles.…”

ResumoAs pequenas frutas, como o mirtilo (Vaccinium spp.), apresentam propriedades nutricionais e alto potencial antioxidante. Práticas de manejo como a época de poda podem provocar diferentes respostas nas plantas, devido a alterações nas condições climáticas a que as plantas estarão expostas durante seu período reprodutivo. O objetivo do presente trabalho foi avaliar o efeito da poda seca sobre a produção e atributos de qualidade dos frutos de mirtileiro, cultivares Clímax, Bluegem e Powderblue, nas condições da mesorregião de Pelotas, RS. Foram utilizadas plantas adultas de mirtileiro (Vaccinium spp.) de pomar comercial, localizado no município de Morro Redondo, RS. Plantas em diferentes parcelas foram submetidas a podas em duas datas: poda 1 em 10 de julho de 2012 e a poda 2 em 10 de agosto de 2012. Frutos colhidos no estadio de maturação completa foram avaliados quanto a produção, teor de sólidos solúveis (SS), acidez total titulável (ATT), pH, cor (°Hue), teor de compostos fenólicos totais, teor de antocianinas totais e potencial antioxidante. A época da poda seca influenciou de forma significativa a produção e os atributos de qualidade dos frutos de mirtilo. A poda, quando realizada na época 1, ocasionou maior produção, entretanto foi na época de poda 2 que as cultivares apresentaram maior teor de compostos fenólicos. As cultivares Bluegem e Powderblue apresentaram ainda maior potencial antioxidante e maior teor de antocianinas.Palavras-chave: Vaccinium spp., atributos de qualidade, fitoquímicos, época de poda. Effect pruning time on yield and quality of blueberry fruitAbstract Small fruit such as blueberry (Vaccinium spp.) present nutraceutical properties and elevated antioxidant potential. Cultural practices such as pruning time can promote various responses in the plants due to the changed environmental conditions that the plants are exposed during their reproductive period. The objective of this study was to evaluate pruning time on production and fruit quality attributes of cultivars Clímax, Bluegem and Powderblue, cultivated in the mesorregion of Pelotas, RS. Adult blueberry plants (Vaccinium spp.) of a commercial orchard, located in Morro Redondo, RS were utilized. Plants of different parcels were submitted to one pruning at different time: pruning 1, in July 10th 2012 and pruning 2 in August 10th 2012. Fruit harvested at the full ripe stage were evaluated for production, soluble solids content (SSC), total titratable acidity (TTA), pH, color (°Hue), total phenolic content, total anthocyanin content and antioxidant potential. Pruning time significantly influenced production and quality attributes of blueberry fruit. Pruning 1 lead to higher production, however, plants pruned at time 2 showed higher phenolic content and cultivars Bluegem and Powderblue also had higher antioxidant potential and higher anthocyanin content.

“…Fruits of the 'O'Neal' cultivar, which also belongs to the same group as 'Snowchaser', were stored at 0 ºC and wrapped in a biodegradable film, and also presented a continuous rise in anthocyanin contents along a 15 day storage period (CHIABRANDO; GIACALONE, 2015). Rodrigues et al (2011) also observed values of 69.97 and 162.85 mg cyanidin-3-glucoside · 100g -1 in fruits of the 'Florida M' and 'Bluebelle' cultivars, respectively.…”

-In Brazil there are still few studies on the post-harvest quality of low-chill blueberry cultivars, which have been recently introduced in the country. 'Snowchaser' blueberries were evaluated during a six-day storage period regarding fruit physical and chemical properties, and its antioxidant capacity. During fruit storage there was an increased weight loss and maintenance of some skin color properties such as luminosity (L*) and b*, whereas the values of parameter a* decreased and chroma (C) values increased. The levels of anthocyanins and flavonoids in the pulp increased, as well as the antioxidant activity. Maximum fruit shelf life at room temperature was six days without reduction on the antioxidant activity along the period, which is beneficial to consumers' health. Index terms: Vaccinium corymbosum, weight loss, color, anthocyanins, flavonoids, antioxidant activity. Atributos de qualidade em frutos de mirtileiro 'Snowchaser' de baixa exigência em frio cultivados no BrasilResumo -Há poucos estudos sobre a qualidade pós-colheita de cultivares de mirtilos de baixa exigência em frio hibernal, recentemente introduzidas no Brasil. Frutos de mirtileiro 'Snowchaser' foram avaliados quanto às propriedades físicas e químicas e também com relação à atividade antioxidante, durante 6 dias de armazenamento. Houve aumento da perda de massa e manutenção das variáveis colorimétricas de luminosidade (L*) e (b*), enquanto os valores da variável a* diminuíram e os de croma aumentaram. Os teores de antocianinas e flavonoides aumentaram, assim como a atividade antioxidante. O período máximo de conservação dos frutos em temperatura ambiente foi de 6 dias, sem redução da atividade antioxidante ao longo do período, o que é benéfico para a saúde dos consumidores. Termos para indexação: Vaccinium corymbosum, perda de massa, coloração, antocianinas, flavonoides, atividade antioxidante. Scientific Communication
