Resumo: | One of the many functions of sunflower (Helianthus annuus L.) is related to the use of its inflorescences in the flower market, which has guaranteed space for this species in floriculture in recent years. Sunflower has been highlighted as an ornamental plant for cutting. Studies have been performed aimed at reducing the size of this species, in order to improve its commercial production, which facilitates the production in field and in protected environments. The use of color shading nets can lead to growth manipulation and to the development of this species. The objective of this study was to evaluate the effect of full sun and the use of color shading nets Aluminet®, blue and red (Chromatinet®), on the development of ornamental sunflower cv. Pollenless Sunflower Sunbright. The studied variables were plant height, leaf number, diameter of the floral stem, inflorescence width and dry matter of leaves, stem and inflorescences. By the anatomical analysis of the leaves, it was possible to determine stomatal density, polar (DP) and equatorial (DE) diameters, as well as the relation DP/DE of adaxial and abaxial epidermis and leaf thickness. It is concluded that the best development of ornamental sunflower plants is observed in full sun and under Aluminet®. |

O girassol vem se destacando como planta ornamental para corte, assim visando adequar a produção comercial, estuda-se a redução de porte desta espécie, o que facilita a produção tanto a campo como em ambientes protegidos. O uso de telas fotoconversoras poderá promover a manipulação do crescimento e desenvolvimento dessa espécie. Objetivou-se avaliar o efeito do pleno sol e o uso das telas fotoconversoras tipo Aluminet®, ChromatiNet®azul e ChromatiNet®vermelha no desenvolvimento de plantas de girassol ornamental cultivar Sunflower Pollenless Sunbright. As variáveis analisadas foram altura da planta, número de folhas, diâmetro da haste floral, diâmetro do capítulo e massa seca das folhas, haste e capítulos. Nas análises anatômicas das folhas determinou-se a densidade estomática, diâmetro polar (DP) e diâmetro equatorial (DE), a relação DP/DE das faces adaxial e abaxial e espessura do limbo foliar. Conclui-se que o melhor desenvolvimento das plantas de girassol ornamental é observado no cultivo a pleno sol e com uso de tela fotoconversora Aluminet®.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASFlores - CultivoPlantas ornamentaisGirassóisInfluence of color shading nets on ornamental sunflower developmentInfluência de telas fotoconversoras no desenvolvimento de girassol ornamentalinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://ornamentalhorticulture.emnuvens.com.br/rbho/article/view/755Ângela Maria Pereira NascimentoSimone Novaes ReisFernanda Carlota NeryIara Cristina Santos CurveloTainá da Cruz TaquesElka Fabiana Aparecida Almeidainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/50049/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALInfluence of color shading nets on ornamental sunflower development.pdfInfluence of color shading nets on ornamental sunflower development.pdfapplication/pdf250114https://repositorio.ufmg.br/bitstream/1843/50049/2/Influence%20of%20color%20shading%20nets%20on%20ornamental%20sunflower%20development.pdf637789e1283e9cb3fa07bd6214fb2186MD521843/500492023-02-15 08:12:01.412oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-02-15T11:12:01Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
