Resumo: | The objective of this experiment was to study the effects of different concentrations of the plant growth regulators prohexadione-calcium (ProCa) on the growth control of tomato seedlings. The experiment was conducted in the forest seedling nursery of the Faculty of Agronomic Sciences - UNESP, Botucatu Campus-SP. The experimental design was completely randomized, composed of five treatments: 0, 50, 100, 200 and 400 mg of the active ingredient (a.i.) of ProCa, with 4 replicates of 30 seedlings. Treatments were applied with a manual CO2 sprayer when seedlings completed 20 days after sowing. Ten days after applying the treatments, seedling growth analysis, SPAD index, gas exchange, chlorophyll a fluorescence and biochemical analyses were all performed. From the results obtained, the conclusion was that ProCa concentrations inhibited seedling growth without compromising the photosynthetic apparatus. |

O experimento foi conduzido no viveiro de mudas florestais da Faculdade de Ciências Agronômicas – UNESP, Campus de Botucatu–SP. O delineamento experimental foi o inteiramente casualizado, composto por cinco tratamentos: 0, 50, 100, 200 e 400 mg de ingrediente ativo (i.a.) de ProCa, com quatro repetições de 30 mudas cada. Os tratamentos foram aplicados com pulverizador manual de CO2 quando as mudas completaram 20 dias após a semeadura. Dez dias após a aplicação dos tratamentos foram realizadas análises de crescimento das mudas, índice SPAD, trocas gasosas, fluorescência da clorofila a e análises bioquímicas. Pelos resultados obtidos foi possível concluir que as concentrações de ProCa inibiram o crescimento das mudas, não comprometendo o funcionamento de seu aparato fotossintético.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilFALE - FACULDADE DE LETRASRevista Brasileira de Ciências AgráriasBotânicaTomate - CultivoPlantas - AnáliseAntioxidant enzymesFluorescenceGrowthSolanum lycopersicum L.Physiological and biochemical aspects of tomato seedlings treated with prohexadione-calciumAspectos fisiológicos e bioquímicos de mudas de tomateiro tratadas com proexadiona cálcicainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://www.agraria.pro.br/ojs32/index.php/RBCA/article/view/v16i2a8652Fabrício Palla TeixeiraAndrew Kim Lopes FerrazRafaelly Calsavara MartinsTainá Mamede Cirne SilvaJoão Domingos RodriguesElizabeth Orika Onoapplication/pdfinfo: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/1843/54934/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALPhysiological and biochemical aspects of tomato seedlings treated with prohexadione-calcium.pdfPhysiological and biochemical aspects of tomato seedlings treated with prohexadione-calcium.pdfapplication/pdf639048https://repositorio.ufmg.br/bitstream/1843/54934/2/Physiological%20and%20biochemical%20aspects%20of%20tomato%20seedlings%20treated%20with%20prohexadione-calcium.pdf2282f3e4a41ac8fb1b54836a7d902bf0MD521843/549342023-06-14 17:14:22.733oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-06-14T20:14:22Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
