Resumo: | The objective of this study was to evaluate the growth, production and fruit quality of blueberry under different plant management. The parameters evaluated in Southern Brasil, were: nitrogen and sulfur dosages and pruning intensity. It was also corrield out a cultivar test to choose, the ones with better fruit quality in environmental conditions of Turin, northern Italy. Four experiments were conducted to reach the objectives: (1) the nitrogen influence, using ammonium sulfate (NH4)2SO4 with 21% N2 and 23% sulfur as a nitrogen source, (2) influence of sulfur dosages (in grams per m3 of pots), (3) evaluation of intensity of pruning, and (4) evaluation of cultivars Aurora, Berkeley, Bluecrop, Bonifacy, Brigittablue, Draper, Duke, Emerald, group 'Northen highbush', and Gulfcoast, Jewel, Legacy, Liberty, Millenia, Misty, The ' Neal, Ozarkblue, Palmetto, Primadonna, Sebring, Snowchaser, SouthernBelle, Springhigh, Springwide, Star Group 'southern highbush'. The last experiment was conducted in Torino, Italy, during the 2011/2012 growth season. In all experiments the variables analyzed were production and fruit quality, achieved through physical and chemical analysis, and the presence of phytochemicals in fruits. In the first two experiments, were also evaluated the minerals present in fruits. The conclusions were: the nitrogen applied on soil does not alter plant growth and productivity. Among the physico-chemical characteristics of fruits, only total acidity is changed according to the nitrogen dosages. Anthocyanins, phenolic compounds and antioxidant activity are influenced by nitrogen. Fruit yield and plant growth were not altered with the sulfur application, in the first production year. Moreover, phenolic compounds exhibit quadratic response and the total acidity decreased influenced by the sulfur applications. In relation to the analysis of cultivars in Italy, Aurora, Draper, Bekeley, Bluecrop, Bonifacy, Brigitta, Legacy, Liberty, may be considered late in the conditions of Torino. The cultivar O'Neal has the most concentrated harvest. The cultivar Jewel is one of the best in respect to physico-chemical composition, but should be further investigated in respect to adaptability. Legacy and Palmetto have high levels of polyphenols, with good fruit size and appearance. |

Os fatores avaliados foram: doses de nitrogênio, doses de enxofre e intensidades de poda. Além disso, foi avaliado, por meio de competição de cultivares, aquelas que apresentavam melhor qualidade de frutos, nas condições edafoclimáticas de Torino, norte da Itália. Para isso foram realizados quatro experimentos. (1) influência de doses de nitrogênio, utilizando como fonte o sulfato de amônio (NH4)2SO4 com 21% de N2 e 23% de enxofre; (2) influência de doses de enxofre em gramas por m3 de substrato; (3) avaliação da intensidade de poda; e (4) avaliação de cultivares Aurora, Berkeley, Bluecrop, Gulfcoast, Jewel, Legacy, Liberty, Millenia, Misty, O'Neal, Ozarkblue, Palmetto,Primadonna, Sebring, Snowchaser, Southernbelle, Springhigh, Springwide, StarItália, durante o ano de (2011/2012). Em todos os experimentos as variáveisresposta foram produção e qualidade de frutos, alcançada por meio de análises físico-químicas e presença de fitoquímicos nos frutos. Nos dois primeiros experimentos foram avaliados, ainda, os mineirais presentes nos frutos. Conclui-se que: as doses de nitrogênio aplicadas no solo não alteram produtividade e crescimento de plantas. Dentre as características físicoquímicas dos frutos, apenas acidez total titulável é alterada pelas doses de nitrogênio. Antocianinas, compostos fenólicos e atividade antioxidante, são influenciadas pelas doses de nitrogênio. A produção de frutos e o crescimento de plantas, não foram alterados com as aplicações de enxofre, no primeiro ano de produção. Por outro lado, compostos fenólicos respondem de forma quadrática e a acidez total diminuiu, influenciada pelas aplicações de enxofre. Quanto à análises das cultivares na Italia, Aurora, Draper, Bekeley, Bluecrop, Bonifacy, Brigitta, Legacy, Liberty, podem ser consideradas tardias, nas condições de Torino. A cultivar O'Neal possui a colheita mais concentrada. A cultivar Jewel é uma das melhores com relação à composição físico-química, mas deve ser melhor estudada com relação à adaptabilidade. Legacy e Palmetto apresentam elevados teores de polifenóis, com frutos de bom tamanho e aparência.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em AgronomiaUFPelBRFaculdade de Agronomia Eliseu MacielVacciniumNitrogênioEnxofrePodaFitoquímicosAdaptaçãoVacciniumNitrogenSulfurPruningPhytochemicalsAdaptationCNPQ::CIENCIAS AGRARIAS::AGRONOMIAAspectos de manejo e cultivares de mirtilo: qualidade e produtividadeManagement aspects and blueberry cultivars: quality and productivityinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALtese_gisely_correa_de_moura.pdfapplication/pdf950084http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1154/1/tese_gisely_correa_de_moura.pdfe2834e43f9fde7d2d8b65bf5826d57d6MD51open accessTEXTtese_gisely_correa_de_moura.pdf.txttese_gisely_correa_de_moura.pdf.txtExtracted Texttext/plain252297http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1154/2/tese_gisely_correa_de_moura.pdf.txt6ea78106245e25fa0cb8214000b269f2MD52open accessTHUMBNAILtese_gisely_correa_de_moura.pdf.jpgtese_gisely_correa_de_moura.pdf.jpgGenerated Thumbnailimage/jpeg1369http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1154/3/tese_gisely_correa_de_moura.pdf.jpg8bf973028db3aac4d5e5c99d0a1bdaf3MD53open access123456789/11542023-05-31 18:56:11.314open accessoai:guaiaca.ufpel.edu.br:123456789/1154Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-05-31T21:56:11Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
