Resumo: | Microgreens are young plants that are consumed at the seedling stage, which present short production cycle and require little space for growing. The objective of the present study was to evaluate the yield and nutritional quality of purple cabbage (Brassica oleracea var. capitata f. rubra) microgreens grown in different substrates and nutrient concentrations in the nutritive solution, in a recirculating irrigation system. The experiment was conducted in a protected environment at the Faculty of Agronomy (UFRGS), in Porto Alegre, RS, Brazil. A completely randomized design and three replications were used, with a 4×3 factorial arrangement consisted of four commercial substrates (CSC® vermiculite, Beifiur® S10, Carolina Soil® seedling, and Carolina Soil® organic) and three nutrient concentrations in the nutritive solution (0%, 50%, and 100%). A sub-irrigation system was used for the irrigations. The variables evaluate were: shoot fresh matter yield (SFMY), shoot dry matter yield (SDMY), shoot height at harvest (SHH), production cycle (precocity), and total soluble solids (TSS), total chlorophyll, and carotenoid contents. The different substrates had no effect on the SFMY, SDMY, and SHH of the purple cabbage microgreens; the increasing addition of nutrients to the nutritive solution increased the values of these variables. The TSS and total carotenoid contents decreased as the nutrient concentration in the nutritive solution was increased. The responses of total chlorophyll contents to the substrates and the nutrient concentrations in the nutritive solution varied. |

O presente estudo teve por objetivo avaliar a produtividade e a qualidade nutricional de microgreens de repolho roxo (Brassica oleracea var. capitata f. rubra) em diferentes substratos comerciais e concentrações de solução nutritiva, em sistema recirculante de irrigação. O experimento foi conduzido em ambiente protegido, no Campus da Faculdade de Agronomia (UFRGS), em Porto Alegre. Utilizou-se o delineamento inteiramente casualizado, com arranjo fatorial 4x3 com 3 repetições. Os tratamentos foram compostos pelas combinações de quatro substratos comerciais, vermiculita CSC® (S1), S10 Beifiur® (S2), Carolina Soil® mudas (S3) e Carolina Soil Orgânico® (S4) e três concentrações (0, 50 e 100%) de nutrientes na solução nutritiva. As irrigações foram realizadas por sistema de subirrigação. Foram avaliadas a produtividade média de massa fresca (MF) e seca (MS) da parte aérea, altura de plântulas, duração de ciclo (precocidade) teor de sólidos solúveis (TSS), clorofilas e carotenoides totais. Os diferentes substratos não influenciaram sobre as variáveis de produtividade de MF e de MS da parte aérea e altura de microgreens de repolho roxo. A adição de nutrientes à solução nutritiva propicia o aumento destas mesmas variáveis. O teor de sólidos solúveis e o conteúdo total de carotenoides reduziu com o aumento da concentração da solução nutritiva. A resposta para o conteúdo total de clorofilas foi inconstante entre os substratos e as diferentes concentrações de nutrientes na solução nutritiva.Universidade Federal Rural do Semi-Árido2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/862210.1590/1983-21252019v32n414rcREVISTA CAATINGA; Vol. 32 No. 4 (2019); 976-985Revista Caatinga; v. 32 n. 4 (2019); 976-9851983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8622/10108Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessWieth, Albertina RadtkePinheiro, Wagner DutraDuarte, Tatiana da Silva2023-07-20T17:56:04Zoai:ojs.periodicos.ufersa.edu.br:article/8622Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:41.232103Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
