Resumo: | This study has as main purpose to evaluate the influence of different color profiles on the cultivation related to temperature and dissolved oxygen concentration in the nutrient solution in the growing of rocket over two growing seasons in hydroponic system NFT. The experiment was conducted in the period of April to August 2012, in protected ambient counting with three production benches each comprised of eight profiles for the conduct of the plants evaluated, having four black and four white painted with plastic paint. The two colors of profile were arranged alternately and, to surround effect, a profile was installed on each edge of the bench. During the experiment, the temperature was recorded and the concentration of dissolved oxygen in the nutrient solution in the profiles three times per day, at 9:00, 15:00 and 21:00. In each reading recorded the temperature and concentration of oxygen at the beginning and end of two profiles of each color. For growth analysis, assessments were performed every four days in two growing seasons, autumn and winter, and the variables were evaluated: leaf dry matter, stem dry mass and root dry mass; plant height; root length; number of leaves and leaf area index. The results were analyzed separately and show that the different colors and profile stations modify the temperature and oxygen concentration of the nutrient solution. The black color profile increased the temperature of the circulating nutrient solution. Changes in temperature affected the concentration of dissolved oxygen in the nutrient solution. The different colors and seasons interfered with the growth of rocket. Plants grown in white profile showed higher leaf dry matter, stem dry mass and root dry mass, as well as increased root length and increased leaf area index. |

O experimento foi realizado no período de abril a agosto de 2012, em ambiente protegido contando com três bancadas de produção cada qual composta por oito perfis para a condução das plantas avaliadas sendo, quatro de cor preta e quatro pintados com tinta plástica branca. As duas cores de perfil foram dispostas alternadamente e, para efeito de bordadura foi instalado um perfil em cada borda da bancada. Durante a condução do experimento, foi registrada a temperatura e concentração de oxigênio dissolvido na solução nutritiva nos perfis três vezes por dia, sendo às 9:00h, 15:00h e 21:00h. Em cada leitura registrava-se a temperatura e concentração de oxigênio no início e final de dois perfis de cada cor. Para a análise de crescimento, as avaliações foram realizadas a cada quatro dias em duas estações de cultivo, outono e inverno, e as variáveis avaliadas foram: massa de folha seca, massa de caule seco e massa de raiz seca; altura de planta; comprimento de raiz; número de folhas e índice de área foliar. Os resultados obtidos foram analisados separadamente e demonstram que as diferentes cores de perfil e estações do ano modificaram a temperatura e concentração de oxigênio da solução nutritiva. A cor preta do perfil aumentou temperatura da solução nutritiva circulante. Mudanças na temperatura influenciaram na concentração de oxigênio dissolvido na solução nutritiva. As diferentes cores de perfil e estações do ano interferiram no crescimento da rúcula. As plantas cultivadas no perfil branco apresentaram maior massa de folha seca, massa de caule seco e massa de raiz seca, bem como maior comprimento de raiz e maior índice de área foliar.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Agronomia - Agricultura e AmbienteUFSMBRAgronomiaEruca sativaOxigenaçãoHidroponiaRegime térmicoÉpoca de cultivoEruca sativOxygenationHydroponicsThermal regimeCultivation environmentCNPQ::CIENCIAS AGRARIAS::AGRONOMIAEfeito da cor do perfil na temperatura e concentração de oxigênio da solução nutritiva em cultivo hidropônico de rúculaThe effect of color profile in temperature and concentration of oxygen in growing hydroponic nutrient solution of rocketinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSchmidt, Denisehttp://lattes.cnpq.br/5512500747950163Souza, Velci Queiróz dehttp://lattes.cnpq.br/6515305945460230Dourado Neto, Durvalhttp://lattes.cnpq.br/1325247019367288http://lattes.cnpq.br/9399272190550984Gabriel, Vilson José5001000000094003003005003007bc377df-4f0e-46fd-af00-51bf31dd475ed55cf807-8806-4287-bab4-556e2e2c227a6e5d01d0-6828-4006-a725-f75d3bdeb0f4d34c1665-e926-427b-b657-6147e18b045cinfo:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALGABRIEL, VILSON JOSE.pdfapplication/pdf1188878http://repositorio.ufsm.br/bitstream/1/4921/1/GABRIEL%2c%20VILSON%20JOSE.pdfd5d862504a7c0c69e412f28c0cfe1430MD51TEXTGABRIEL, VILSON JOSE.pdf.txtGABRIEL, VILSON JOSE.pdf.txtExtracted texttext/plain151721http://repositorio.ufsm.br/bitstream/1/4921/2/GABRIEL%2c%20VILSON%20JOSE.pdf.txt246438ecf2d01ae15f9806e6a4654e0aMD52THUMBNAILGABRIEL, VILSON JOSE.pdf.jpgGABRIEL, VILSON JOSE.pdf.jpgIM Thumbnailimage/jpeg5936http://repositorio.ufsm.br/bitstream/1/4921/3/GABRIEL%2c%20VILSON%20JOSE.pdf.jpg583d8e0cec901d069ab2caf8ed38f74aMD531/49212022-01-10 08:42:51.618oai:repositorio.ufsm.br:1/4921Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-01-10T11:42:51Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
