Resumo:  Flowers of zinnia (Zinnia elegans Jacq.) are well adapted to the growing conditions of South-eastern Brazil, and have excellent potential to be commercialized as cut flower. This work aimed to evaluate the influence of sucrose, applied as pulsing solution, and the effect of periodical recuts on the stem base on the flowers longevity and flowers water uptake. Cut inflorescences with similar length were pulsed for six hours with 0, 5, 10, 15 and 20% sucrose or with 10% sucrose for 0, 6, 12, 18 and 24 hours, with or without recuts at stem base at every 48 hours. Treatments with 5, 10, 15 and 20% sucrose for six hours did not affect flower longevity compared to untreated flowers. Recuts on the stem base improved water uptake and extended the flower longevity. Pulsing the inflorescences with 10% sucrose for 18 or 24 hours hastened flower senescence in vase. Ethylene production was inhibited by increasing the concentration of sucrose in the pulsing solution

O presente trabalho objetivou avaliar a influência da sacarose aplicada na forma de solução de condicionamento, e do corte periódico da base das hastes sobre a longevidade e absorção de água pelas flores. Hastes florais uniformizadas em tamanho foram submetidas ao condicionamento, por seis horas, com sacarose a 5, 10, 15 e 20% ou com soluções de 10% de sacarose por 0, 6, 12, 18 e 24 horas, com ou sem cortes periódicos na base das hastes a cada 48 horas. O tratamento das flores por seis horas com sacarose a 5, 10, 15 ou 20% não afetou a longevidade das flores, comparado àquelas mantidas somente com água destilada. O corte periódico da base das hastes promoveu melhor suprimento de água às flores, estendendo a longevidade. O condicionamento das flores com 10% de sacarose por 18 ou 24 horas acelerou a senescência das flores em vaso. A taxa de produção de etileno foi inibida pelo aumento da concentração de sacarose na solução de condicionamento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarneiro, Tânia ForsterFinger, Fernando Luizdos Santos, Vanessa RebouçasNeves, Ludmila Lafetá de MeloBarbosa, José Geraldo2002-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6439Pesquisa Agropecuaria Brasileira; v.37, n.8, ago. 2002; 1065-1070Pesquisa Agropecuária Brasileira; v.37, n.8, ago. 2002; 1065-10701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6439/3496info:eu-repo/semantics/openAccess2010-08-25T13:22:19Zoai:ojs.seer.sct.embrapa.br:article/6439Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-25T13:22:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
