Resumo: 'Gala' apples were stored in controlled atmosphere with 1 kPa O2/3 kPa CO2 at 1°C, with the aim to evaluate the effect of relative humidity (RH) and ethylene removal on fruit quality. Treatments were combinations of ethylene concentration and levels of RH. The relative humidity was maintained around 97% for treatments with high relative humidity and around 94% for treatments with low RH during the two initial and two last months of storage. The treatments with low ethylene concentration were maintained with 0.0 to 1.0 µL/L and 0.0 to 1.5 µL/L whereas the treatment without ethylene removal had about 100 µL/L. After eight months of storage, lowering relative humidity to 94%, during two initial and last storage months showed higher flesh firmness, however with more shriveling at chamber opening and after seven days shelf-life. Internal breakdown and yellowing of fruits were observed with low RH after shelf-life. Ethylene removal maintained higher flesh firmness and retained green ground color and juiciness of fruits after eight months of storage.

Os tratamentos foram combinações de níveis de umidade relativa e concentrações de etileno. A umidade relativa do ar foi mantida em torno de 97% para os tratamentos com alta umidade relativa, e em torno de 94% para aqueles com umidade reduzida nos dois meses iniciais e finais de armazenamento. Os tratamentos com baixos níveis de etileno consistiram de concentrações de 0,0 a 1,0 µL/L e de 0,0 a 1,5 µL/L, enquanto o tratamento sem absorção apresentava em torno de 100 µL/L. Após oito meses de armazenamento, a redução da umidade relativa a 94%, nos dois meses iniciais, ou para os dois finais, do armazenamento proporcionou firmeza de polpa mais elevada, porém com maior murchamento tanto na abertura das câmaras como após sete dias de exposição dos frutos à temperatura ambiente. A degenerescência interna e a coloração mais amarelada da epiderme foram constatadas com reduzida umidade relativa dos frutos à temperatura ambiente. A absorção de etileno manteve a firmeza da polpa sensivelmente mais elevada, a coloração da epiderme mais verde e a maior suculência dos frutos após oito meses de armazenamento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBrackmann, AuriCeretta, Marcelo1999-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5549Pesquisa Agropecuaria Brasileira; v.34, n.12, dez. 1999; 2169-2174Pesquisa Agropecuária Brasileira; v.34, n.12, dez. 1999; 2169-21741678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5549/2740info:eu-repo/semantics/openAccess2010-06-29T16:28:34Zoai:ojs.seer.sct.embrapa.br:article/5549Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-29T16:28:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
