Resumo: | The objective of this study was to evaluate the effects of soil K fertilization on fruit mineral composition, quality and storability of 'Fuji' apples. Fruits from a long-term trial that evaluated apple response to annual soil applications of K2O for nine years were harvested in the 1999/2000 growing season and stored in controlled atmosphere (CA) of 1 kPa O2/ < 0.3 kPa CO2 or 1 kPa O2/2.0 kPa CO2. Apples were analyzed for quality and ripening parameters at harvest, after eight months of CA storage, and after seven days at 20ºC after harvest and after CA storage. The increase on soil K fertilization raised fruit mass, diameter, titratable acidity, red color, and K contents while decreased flesh firmness. There was a significant interaction between K fertilization and storage atmospheres only for internal breakdown: when fruits were stored under 1 kPa O2/ < 0.3 kPa CO2 no differences were determined between treatments. However, storing apples under 1 kPa O2/2.0 kPa CO2 resulted in higher breakdown in fruits with lower K concentrations. Fruit weight losses during storage, ground color and rot incidence were not affected by soil K fertilization in the previous nine years. |

Os frutos utilizados foram provenientes de um experimento em que, durante nove anos, aplicaram-se doses crescentes de K2O no solo. As maçãs foram coletadas na safra 1999/2000 e armazenadas em atmosfera controlada (AC) nas condições de 1 kPa O2/ < 0,3 kPa CO2 ou 1 kPa O2/2,0 kPa CO2. As avaliações qualitativas foram realizadas na colheita, após oito meses de armazenamento, aos sete dias após a colheita e aos sete dias após oito meses de armazenamento. Nesses sete dias, os frutos permaneceram em temperatura de 20oC. O incremento no fornecimento de K às plantas aumentou o diâmetro, massa, acidez, coloração vermelha e a concentração de K nos frutos. Em contrapartida constatou-se diminuições da firmeza da polpa com aumento das doses de potássio. Houve interação entre a adubação e as condições de armazenamento somente em relação à degenerescência de polpa. Não houve diferenças entre os tratamentos quando os frutos foram armazenados em AC de 1 kPa O2/ < 0,3 kPa CO2. Quando as maçãs foram armazenadas em AC de 1 kPa O2/2,0 kPa CO2, observou-se maior degenerescência naqueles frutos com menor concentração de potássio. A perda de peso durante o armazenamento, a cor de fundo da epiderme e a ocorrência de podridões não foram afetados pelas doses de potássio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHunsche, MaurícioBrackmann, AuriErnani, Paulo Roberto2003-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6598Pesquisa Agropecuaria Brasileira; v.38, n.4, abr. 2003; 489-496Pesquisa Agropecuária Brasileira; v.38, n.4, abr. 2003; 489-4961678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6598/3655info:eu-repo/semantics/openAccess2014-08-13T16:56:49Zoai:ojs.seer.sct.embrapa.br:article/6598Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-13T16:56:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
