Ponto de colheita ideal de mangas 'Tommy Atkins' destinadas ao mercado europeu

Abstract: Este trabalho foi desenvolvido em um pomar comercial do Pólo Agrícola Mossoró-Assu, localizado no município de Assu-RN. Teve como objetivo caracterizar e determinar o melhor estádio de maturação para a colheita de mangas 'Tommy Atkins' destinadas ao mercado Europeu. Os frutos foram marcados e avaliados aos 82 (E1), 89 (E2), 96 (E3) e 103 (E4) dias após a floração plena (DFP) e no estádio de colheita comercial (EC)., As avaliações foram feitas por ocasião da colheita e após 21 dias de armazenamento refrigerado … Show more

“…Differently, the linear regression analysis that verified correlation of storage days with pH, showed that these parameters are highly correlated (R 2 = 0.90); thus, the longer the storage time, the higher the fruit pH, which indicates that, physiologically, fruits matured over time ( Figure 4C). Morais et al (2002) reported that during ripening, mangoes tend to increase pH and decrease acidity, as observed in this study. Analysis of the titratable acidity showed that there was a progressive reduction in the contents throughout the storage period in all treatments ( Figure 4D).…”

“…O período de maturação médio da manga variedade 'Alfa' obtido neste trabalho foi de 112 dias para atingir o ponto de colheita. O intervalo de confiança da média para um nível de significância de 0,05 ficou entre 102 e 121 dias, que é superior aos 96 dias após a floração plena observados por Morais et al (2002) …”

“…Apesar de subjetivos, métodos de coloração externa do fruto apresentam maiores possibilidades de uso. Morais et al (2002) encontraram alta correlação entre o método de avaliação da cor da casca através de escala subjetiva com outros parâmetros de maturação do fruto de manga.…”

“…Similar behavior was watched for flesh firmness and acidity parameters, where the fruits classified as class 4 (highest DA-IDA), present significant difference compared to others classes, featuring fruits more firm and acid. The decrease of the acidity values can be associated to ripening and maturation, due to the consumption of acid in the respiratory process (MORAIS et al, 2002) or in routes of conversion of the flavoring components. According to Jerônimo et al 2007, loss of acidity is desirable in most fruits and outstanding in the ripening process.…”
