Qualidade industrial e maturação de frutos de laranjeira "valência" sobre seis porta-enxertos

Abstract: Com o objetivo de avaliar a influência de seis porta-enxertos sobre a maturação e as características físico-químicas de frutos de laranjeira 'Valência', instalou-se um experimento em janeiro de 1994, no município de Nova Esperança-PR. O delineamento experimental foi de blocos ao acaso, com quatro repetições, três plantas úteis por parcela e seis tratamentos, constituídos pelos porta-enxertos: limoeiro 'Cravo' (Citrus limonia), tangerineiras 'Cleópatra' (C. reshni) e 'Sunki' (C. sunki), citrangeiro 'Troyer' (Po… Show more

“…The lowest SS/AT ratio average, 18.25, was observed at the end of the storage period (Table 1) and was higher than the highest value reported by Auler, FIORI-Tutida and Scholz (2009) and Rapisarda et al (2008) for 'Valencia' oranges grown in mild climate conditions. Auler, Fiori-Tutida and Scholz (2009), studying the effect of six rootstocks on quality of 'Valencia' oranges, observed that SS/TA ratio did not differ with the rootstocks. In that study, 'Troyer' citric rootstock yielded the highest SS/AT ratio, 12.0.…”

“…Quanto ao índice tecnológico (média de 1,70), produtividade (média de 3,35 caixa de 40,8 kg por planta) e o número de sementes por fruto (média de 12 sementes) não se verificaram diferenças entre os genótipos comparadas apenas na última avaliação. O índice tecnológico médio obtido foi inferior aos reportados por Stuchi et al (2002) e Tazima et al (2008) para a cultivar Valência, com média de 2,85 e 2,16, respectivamente, além de inferior ao máximo obtido por Auler et al (2009), de 2,10, e por Blumer et al (2003), de 2,52 a 2,73, para cultivares de maturação tardia. Este fato deve-se à combinação de baixos valores de sólidos solúveis e rendimento de suco encontrados neste trabalho, provavelmente, devido à época com excesso de chuvas e dias nublados da região Amazônica.…”

“…Although TA was not influenced by the fruit maturation stages, TSS was what significantly influenced this ratio. This increase in TSS/TA observed with the development of the fruits is a behavior resulting from the increase in total sugars and degradation of organic acids, given that this parameter expresses the fruit ripeness and quality index (Auler, Fiori-tutida, & Scholz, 2009). Rodrigues et al (2014) evaluated the TSS/TA ratio in P. peruviana L. fruits grown in a greenhouse in Lavras-MG when they showed a yellowish calyx and found a maximum value of 8.8.…”
