Resumo: This work evaluated the influence of the aminoethoxyvinylglycine (AVG), an inhibitor of ethylene synthesis, when applied in pulsing solution or sprayed, on the abscission and longevity of cut star orchid (Epidendrum ibaguense Kunth) inflorescences. The cut stems were placed in solutions with 0, 0.5, 1, 1.5 and 2 mM AVG concentrations immediately after the harvest for periods of 6, 12, 18 and 24 hours. The same treatment concentrations were sprayed on the inflorescences until runoff. The experiment had a randomized complete block design with factorial treatments of rate and duration plus rate of application to the flowers, with five replicates, with three stems per experimental unit. Regardless of the way the AVG was applied, the inhibitor extended the flowers' longevity in approximately 70% compared to the control treatment, reaching maximum effect at 1.5 and 2 mM AVG. The percentage of abscissed flowers diminished in all treatments containing AVG, with higher efficiency when sprayed over the inflorescence, decreasing the abscission by 80% at concentrations between 1 and 2 mM AVG.

As hastes foram colhidas e imediatamente condicionadas em solução com 0, 0,5, 1, 1,5 e 2 mM de AVG por 6, 12, 18 e 24 horas. Os mesmos tratamentos foram aplicados na forma de pulverização até o molhamento completo da inflorescência. O experimento foi conduzido em um esquema fatorial entre tempo de aplicação e doses de AVG, mais doses de AVG aplicadas em pulverização nas flores, e o delineamento foi em blocos ao acaso, com cinco repetições, com três hastes por unidade experimental. Independentemente do modo de aplicação do AVG, as concentrações utilizadas promoveram aumento da longevidade das flores em aproximadamente 70% em comparação ao controle, com resposta máxima nas concentrações de 1,5 e 2 mM. A percentagem de abscisão de flores foi reduzida em todos os tratamentos com AVG, principalmente quando se utilizou pulverização, com decréscimo na abscisão acumulada superior a 80% nas concentrações entre 1 e 2 mM de AVG. A aplicação de AVG prolonga a longevidade e reduz a abscisão de flores de Epidendrum ibaguense.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPEMIGMapeli, Ana MariaFinger, Fernando LuizOliveira, Lucilene SilvaBarbosa, José Geraldo2010-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1386Pesquisa Agropecuaria Brasileira; v.44, n.3, mar. 2009; 258-262Pesquisa Agropecuária Brasileira; v.44, n.3, mar. 2009; 258-2621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1386/5674https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1386/1098https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1386/1099info:eu-repo/semantics/openAccess2014-12-09T17:12:16Zoai:ojs.seer.sct.embrapa.br:article/1386Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-09T17:12:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
