Resumo: Sunflower (Helianthus annuus L.) has great economic importance due to its oil yield and quality. Among the factors influencing these parameters, nitrogen fertilization stands out. In this study we evaluated the effect of different N-urea doses (0,10,30,50,90,130 kg N-urea ha-1) at planting and 30 days after emergency on soluble fractions, oil profile and yield of three sunflower cultivars (BRS324, Catissol 01and Neon). Plants were harvested at the flowering stage for metabolic study, and at the end of the cycle for oil extraction and characterization. The Catissol 01 genotype presented the highest N-NO3- accumulation capacity, mainly in the stem. The Neon genotype presented the highest achene production at 30 and 50 kg N ha-1. Oleic oil had the highest yield, with the Catissol 01 and Neon cultivar standing out. Among the cultivars, Catissol 01 is economically more suitable for biofuel production, when cultivated at 50 kg N ha-1 since higher N doses did not result in increased oil yield.

Entre os fatores que influenciam esses parâmetros se destaca a fertilização nitrogenada. Este trabalho avaliou o efeito de doses crescentes de N-uréia (0, 10, 30, 50, 90, 130 kg de N-Uréia ha-1 aplicadas no plantio e aos 30 dias após a emergência) sobre as frações solúveis, rendimento e perfil do óleo de três genótipos de girassol (BRS324, Neon e Catissol 01). As plantas foram coletadas no estádio de floração para o estudo metabólico e ao final do ciclo para a extração e caracterização de óleo. O genótipo Catissol 01 apresentou maior capacidade de acúmulo de N-NO3-, preferencialmente no caule. A maior produção de óleo por planta foi observada no BRS324, nas doses entre 30 e 50 kg N ha-1, embora o genótipo Neon tenha apresentado a maior produção de aquênios. O ácido oléico foi o de maior rendimento com destaque para os genótipos Catissol 01 e Neon. Dentre os genótipos avaliados, o Catissol 01 é economicamente mais indicado para a produção de óleo destinada ao biocombustível, quando cultivado com a dose de 50 kg N ha-1, pois doses superiores de N não resultam em aumento na produção de óleo.EDUFU2020-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4781610.14393/BJ-v36n0a2020-47816Bioscience Journal ; Vol. 36 (2020): Supplement1; 266-279Bioscience Journal ; v. 36 (2020): Supplement1; 266-2791981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/47816/31213Brazil; Contemporary Copyright (c) 2020 Janiélio Gonçalves da Rocha, Luiziene Soares Alves, Orlando Carlos Huertas Tavares, Elvia Mariam Lis Martinez Stark, Manlio Silvestre Fernandes, Rosane Nora Castro, André Marques dos Santos, Sonia Regina de Souzahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha, Janiélio Gonçalves daAlves, Luiziene SoaresTavares, Orlando Carlos HuertasStark, Elvia Mariam Lis MartinezFernandes, Manlio SilvestreCastro, Rosane Nora Santos, André Marques dosSouza, Sonia Regina de2022-05-26T18:00:44Zoai:ojs.www.seer.ufu.br:article/47816Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-26T18:00:44Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
