Gaia: | The growth in the production of strawberries requires the use of new technologies. These are the different production systems, aiming to increase the quality and productivity of fruits. The quality of the fruit respect of various parameters, including the content of phenolic compounds, especially the class of anthocyanins, which give the intense red fruit and have great potential antioxidant. This study aimed to assess the phenolic composition of different cultivars in different systems of cultivation and harvest period. To achieve this goal the work was divided into three experiments. In the first pH was determined that best represents the level of anthocyanins in the fruits of strawberry cv. Oso Grande, using spectroscopic methods. Treatments consisted of the following for pH 1.0, 3.0, 4.5; 7.0; 9.0, 13.0. In the second experiment was determined the content of phenolic compounds in four cropping systems and three harvest period, and the treatments (system of cultivation and harvest period) were arranged in a 4 x 3 factorial. The data were analyzed in split plot in time, where the main plot and subplot systems consisted of the seasons. In the third study, was evaluated the content of phenolic compounds in different cultivars and harvest period. In this, the treatments consisted of thirteen and three cultivars harvest period, analyzed the same way that the experiment two. The results in the three trials were submitted to the analysis of variance and differences compared by Tukey test of the 5% significance. The data indicate that the first experiment to extract greater efficiency with the anthocyanins, must be used extrativas solutions at pH 1, because it provides a profile analysis by the classic by ultraviolet spectroscopy. The second work shows that the systems in conventional horizontal bags, as well as the proximity of summer increases the levels of the compounds evaluated. Analyzing the cultivars in the third experiment, it is clear that the cultivars of days neutral Verão and Sielva and cultivar of short days Tudla have high levels of the compounds. As the harvest period, there is the same behavior of the second experiment, except for cultivating Diamante showed that levels constant over the harvests |

Entre essas encontram-se os diferentes sistemas de produção, visando o aumento da qualidade e da produtividade de frutos. A qualidade do fruto diz respeito a diversos parâmetros, dentre eles, o teor de compostos fenólicos, principalmente da classe dos antocianos, que conferem a cor vermelha intensa aos frutos e apresentam grande potencial antioxidante. O presente estudo teve por objetivo avaliar a composição fenólica de diferentes cultivares em diferentes sistemas de cultivo e épocas de colheita. Para atingir este objetivo o trabalho foi dividido em três experimentos. No primeiro foi determinado o pH que melhor representa o teor de antocianos em frutos de morangueiro cv. Oso Grande, utilizando métodos espectroscópicos. Os tratamentos constaram dos seguintes valores de pH 1,0; 3,0; 4,5; 7,0; 9,0; 13,0. No segundo experimento foi determinado o teor de compostos fenólicos em quatro sistemas de cultivo e três épocas de colheita, sendo que os tratamentos (sistema de cultivo e épocas de colheita) foram dispostos em um fatorial 4 x 3. Os dados foram analisados em parcelas subdivididas no tempo, onde a parcela principal constou dos sistemas e a subparcela as épocas. Com relação ao terceiro trabalho, foi avaliado o conteúdo de compostos fenólicos em diferentes cultivares e épocas de colheita. Nesse, os tratamentos constituíram de treze cultivares e três épocas de colheita, analisados da mesma forma que o experimento dois. Os resultados nos três experimentos foram submetidos à análise de variância e as diferenças comparadas pelo teste de Tukey à 5% de significância. Os dados do primeiro experimento indicam que para extrair com maior eficiência as antocianinas, deve-se utilizar soluções extrativas em pH 1, pois fornece um perfil clássico na análise por espectroscopia por ultravioleta. Já o segundo trabalho mostra que os sistemas convencional e em sacolas horizontais, como também a proximidade do verão incrementa os teores dos compostos avaliados. Analisando as cultivares no terceiro experimento, constata-se que as cultivares de dias neutros Verão e Sielva e a cultivar de dias curtos Tudla apresentam teores elevados dos compostos. Quanto as épocas de colheita, verifica-se o mesmo comportamento do segundo experimento, exceto para a cultivar Diamante que apresentou teores constantes ao longo das colheitasUniversidade de Passo FundoFaculdade de Agronomia e Medicina Veterinária – FAMVBRUPFPrograma de Pós-Graduação em AgronomiaCalvete, Eunice Oliveirahttp://lattes.cnpq.br/9631039930870527Reginatto, Flávio HenriqueBordignon Júnior, Celso Luiz2025-06-20T16:42:50Z2008-02-25info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfhttps://repositorio.upf.br/handle/123456789/9401porinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UPFinstname:Universidade de Passo Fundo (UPF)instacron:UPF2025-12-30T19:49:10Zoai:repositorio.upf.br:123456789/9401Repositório InstitucionalPRIhttp://repositorio.upf.br/oai/requestjucelei@upf.br||biblio@upf.bropendoar:16102025-12-30T19:49:10Repositório Institucional da UPF - Universidade de Passo Fundo (UPF) |
