Resumo: The search for techniques that extend shelf life of guava (Psidium guajava) fruits, and reduce its postharvest losses is desirable. The objective of this work was to evaluate the effects of concentrations of competitive ethylene antagonist 1-methylcyclopropene (1-MCP) on conservation of 'Pedro Sato' guava fruits. Treatments consisted of 0, 100, 300 or 900 nL L-1 of 1-MCP for 3 hours followed by storage at 25ºC, and 10ºC with 90±5% RH. The application of 900 nL L-1 1-MCP for 3 hours was efficient in delaying loss of skin color, and in keeping fruit firmness at both storage temperatures. The 300 nL L-1 of 1-MCP concentration was efficient in delaying skin color loss only when fruits were stored at 10ºC. The effect of 1-MCP was quite significant on the reduction of rot incidence at both storage temperatures. The respiratory rate was lower in fruits treated with 300 and 900 nL L-1 of 1-MCP during storage at 25ºC. The product was efficient in delaying the ripening of fruits, and the concentration of 900 nL L-1 showed the best effect.

O objetivo deste trabalho foi avaliar os efeitos e concentrações do antagonista competitivo do etileno, 1-metilciclopropeno (1-MCP), na conservação de goiabas 'Pedro Sato'. Os frutos foram tratados com 0, 100, 300 e 900 nL L-1 de 1-MCP durante três horas, e armazenados a 25ºC e a 10ºC com 90±5% UR. A aplicação de 900 nL L-1 de 1-MCP foi eficiente em retardar a perda de coloração da casca e em manter a firmeza dos frutos, nas duas temperaturas de armazenamento. A concentração de 300 nL L-1 de 1-MCP retardou a perda de coloração da casca, quando os frutos foram armazenados a 10ºC. O efeito do 1-MCP foi bastante significativo em diminuir a incidência de podridões, nas duas temperaturas de armazenamento. A taxa respiratória foi menor nos frutos tratados com 300 e 900 nL L-1 de 1-MCP, durante o armazenamento a 25ºC. O 1-MCP foi eficiente em retardar o amadurecimento dos frutos e a concentração de 900 nL L-1 produziu o melhor resultado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBassetto, ElianeJacomino, Angelo PedroPinheiro, Ana Luiza2005-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6975Pesquisa Agropecuaria Brasileira; v.40, n.5, maio 2005; 433-440Pesquisa Agropecuária Brasileira; v.40, n.5, maio 2005; 433-4401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6975/4023info:eu-repo/semantics/openAccess2014-09-22T18:10:06Zoai:ojs.seer.sct.embrapa.br:article/6975Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-22T18:10:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
