          Abstract

          Os objetivos deste trabalho foram caracterizar a fisiologia e avaliar os efeitos da temperatura e da aplicação de 1-metilciclopropeno (1-MCP) na qualidade pós-colheita de frutos de goiaba-serrana (Acca selowiana), em acessos do banco ativo de germoplasma da Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina. Os frutos foram colhidos na maturação comercial. Os genótipos Brasil (acesso 387) e Uruguai (acesso 454) foram avaliados quanto ao comportamento respiratório e de produção de etileno a 20ºC, e taxas respiratórias e alterações na cor da casca a 0, 5, 10, 20 e 30ºC. O genótipo Brasil (acesso 242) foi avaliado quanto ao amadurecimento a 4ºC, após tratamento com 1-MCP (0, 500 e 1.500 ppb). Os genótipos Brasil (acesso 387) e Uruguai (acesso 454) apresentaram comportamento climatérico, com picos de produção de etileno e de taxa respiratória aos 8 e 12 dias de armazenamento a 20ºC, respectivamente. Não houve diferença significativa entre as taxas respiratórias e de produção de etileno entre os genótipos, nessa temperatura. Houve aumento substancial na taxa respiratória em ambos os genótipos, com o aumento de 0 para 30ºC, com coeficiente metabólico de 3,5 aproximadamente. Com o aumento na temperatura, houve maior alteração na cor verde da epiderme, em frutos do tipo Brasil, e maior escurecimento da epiderme, em frutos do tipo Uruguai. Frutos do genótipo Brasil (acesso 242), tratados com 1-MCP e armazenados a 4ºC, apresentaram retardamento no amadurecimento.

          The objectives of this work were to characterize the postharvest physiology and to evaluate the effects of temperature and treatment with 1-methylcyclopropene (1-MCP) on the postharvest quality of fruits of feijoa (Acca selowiana) accessions from the germplasm bank of Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina. Fruits were harvested at commercial maturity. The genotypes Brasil (accession no. 387) and Uruguai (accession no. 454) were evaluated for respiration and ethylene production at 20ºC, and respiration rates and skin color alterations at 0, 5, 10, 20, 30ºC. The genotype Brasil (accession no. 242) was evaluated for ripening at 4ºC, after treatment with 1-MCP (0, 500 and 1,500 ppb). Brasil (accession no. 387) and Uruguai (accession no. 454) exhibited a climacteric pattern, with a peak of ethylene evolution and respiration rate at the 8th and 12th days of storage at 20ºC, respectively. There was no significant difference for respiration rates and ethylene evolution between these genotypes at this temperature. There was a substantial increase of respiration rate in both genotypes with the increase in temperature from 0 to 30ºC, with a metabolic coefficient of approximately 3.5. With the increase in temperature, fruits of the genotype Brasil showed the greatest change of skin green color, while fruits of the genotype Uruguai exhibited the greatest darkening of skin. Feijoa fruits of genotype Brasil (accession no. 242) had delayed ripening when treated with 1-MCP and stored at 4ºC.
