Resumo: | The present study aimed at the conservation of avocado 'Hass' with the use of 1-methylcyclopropene (1- MCP). The fruits after harvest were selected and exposed to different concentrations of 1-MCP (200 ppm, 300 ppm and 400 ppm) and after the procedure they were stored at 10 º C ± 1 to 90 ± 5% RH. Analyses of weight loss, firmness, enzyme activity of polyphenoloxidase (PPO) and polygalacturonase (PG). The analyzes were performed on fruit every 3 days for 15 days, after this period they were transferred to ambient conditions (23 ± 4 ° C and 70 ± 5% RH) for simulation of marketing. After 3 days at ambient conditions the last appreciation was performed. The experimental design was completely randomized with three replicates per treatment, using the Tukey test at 5% probability. The fruits under application of high doses of 1-MCP showed less weight loss over time. The 1-MCP was effective in maintaining fruit firmness but showed no effect on the enzymes polygalacturonase and pectin. |

Os frutos após a colheita foram selecionados e expostos a diferentes concentrações de 1- MCP (200 ppm, 300 ppm e 400 ppm) e após o procedimento foram armazenados sob refrigeração a 10ºC±1 e 90±5% de UR. Foram realizadas análises de perda de massa fresca, textura, e a quantificação de enzimas poligalacturonase e pectinametilesterase. As análises foram realizadas nos frutos a cada 3 dias, durante 15 dias, depois desse período os mesmos foram armazenados em condições ambiente ( 23±4ºC e 70±5% de UR) para simulação das condições de comercialização. Após 3 dias em condições ambientes foi realizada a última avaliação (dia 18). O delineamento utilizado foi inteiramente casualizado, com 3 repetições por tratamento, utilizando-se o teste de Tukey a 5% de probabilidade. Os frutos sob aplicação de altas doses de 1-MCP apresentaram menor perda de massa ao longo do tempo. O 1-MCP foi eficiente na manutenção da firmeza dos frutos porém não demonstrou efeitos sobre as enzimas poligalacturonase e pectinametilesterase.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Horticultura, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Horticultura, Botucatu, SP, BrasilUniversidade Estadual Paulista (Unesp)Cábia, Nathalie Cardoso [UNESP]Vieites, Rogério Lopes [UNESP]2016-04-01T18:45:56Z2016-04-01T18:45:56Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article129-134http://dx.doi.org/10.17224/EnergAgric.2013v28n2p129-134Energia na Agricultura, v. 28, n. 2, p. 129-134, 2013.1808-8759http://hdl.handle.net/11449/13749510.17224/EnergAgric.2013v28n2p129-134Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporEnergia na Agriculturainfo:eu-repo/semantics/openAccess2024-04-30T14:33:03Zoai:repositorio.unesp.br:11449/137495Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T14:42:28.582263Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
