| En los últimos años se han desarrollado nuevos cultivares de durazno (Prunus pérsica (L) Batsch) con bajo requerimiento de frio y es necesario evaluar su comportamiento postcosecha. En este estudio, se realizaron tratamientos con y sin refrigeración almacenados a una, dos y tres semanas a 5°C, evaluándose características de calidad como firmeza, cambios en color, acidez titulable, °Brix, Relación °Brix/acidez, pérdida de peso, producción de etanol y Acetaldehido, intensidad respiratoria y producción de etileno. Se realizaron evaluaciones semanales fuera de refrigeración a temperatura ambiente 20 ± 2 °C y 50-60 % de humedad relativa. Los resultados mostraron la pérdida de firmeza en todos los cultivares, el CP-2005 presentó la mayor firmeza con 5.3kg. La... |

| Abstract Two experiments were carried out to evaluate the relationship between dry matter content (DMC) and maturity index of ‘Fuji’ apple fruit sports (‘Mishima’, ‘Fuji Select’ and ‘Fuji Suprema’) during the final stage of fruit growth, and the relationship between DMC at harvest and the post-harvest fruit quality. Fruit were harvested from orchards of three regions (Caçador, São Joaquim and Vacaria), on two rootstocks (M9 and Marubakaido with M9 interstock). In experiment 1 (2014), fruit were periodically sampled beginning 83 days before the commercial harvest period. In experiment 2, fruit were harvested at optimum maturity for long-term storage and stored in air at 0.5 ºC (2014) or after optimum maturity for long-term storage and stored in controlled... |

| Abstract The research work aimed at investigating the effect of pre-harvest gibberellic acid (GA3) treatment on the quality of ‘Obilnaja’ and ‘Black Star’ Japanese plum varieties. GA3 was sprayed onto the trees during the fruit color break at 0, 25, 50, 75, and 100 ppm concentrations. After pre-cooling, the plums were placed in modified atmosphere packages and exposed to the following conditions as follows: short storage-transportation (ST) [20 days at 2 °C and 90% relative humidity (RH)]; distribution center (DC) (5 days at 6 °C and 80% RH), and shelf life conditions (SL) (2 days at 20 °C and 70% RH). Pre-harvest GA3 treatments increased the fruit weight and size. Treatment of GA3 at 50, 75, and 100 ppm increased the fruit flesh firmness and total soluble... |
