| Crop rotation improves potato (Solanum tuberosum L.) crops; however, in some cases, it can have some negative effects due to the herbicides previously used in crops under rotation. These effects are the decline in the yield and the appearance of physiological disorders, including cracked tubers, which impair the quality and economic value of the potato. Two field experiments were performed with applications of tembotrione and atrazine, alone or in combination. In the Rio Paranaiba (Minas Gerais State) area, in clay soil, the herbicides were applied at post-emergence in corn (Zea mays L.). After corn harvest and soil preparation, the potatoes were planted. In the Serra do Salitre (Minas Gerais State) area, in the medium texture soil, the herbicides were... |

| A study was carried out to determine the effects of two cooling systems and the application of 1-methylcyclopropene (1-MCP, SmartFreshTM) on the incidence of superficial scald in apples (Malus domestica Borkh.) cv. Granny Smith. Fruit were collected from a commercial orchard (Colbún, Maule Region, Chile) during 2004-2005 season. A completely randomized design was used in a 2 x 2 factorial arrangement, using cooling systems (normal and step-wise cooling) and application of 1-MCP (0 and 625 nL L-1 i.a.) as the main factors. Fruit from normal cooling were kept at 0 °C throughout the storage period (180 days). Step-wise cooling consisted of storing the fruit at 10 °C for 10 days; 4 °C for the next 20 days and 0 °C for the remaining 150 days. Every month,... |

| Abstract The objective of this work was to evaluate the effect of ethanol vapor during storage in modified atmosphere on the ripening and maintenance of the postharvest quality of ‘Laetitia’ plums. The plums were obtained from an orchard in the municipality of Lages, SC. The experimental design adopted was completely randomized. The treatments evaluated were ethanol vapor doses (0, 2, 4, 6 and 8 mL kg-1 of fruit). The fruits were stored at 0.5±0.2°C and 92±2% RH for 30 days. Upon their removal from storage followed by another three days in room conditions (20±5ºC and 63±2% RH), the fruits were evaluated in relation to their physical and chemical attributes, incidence and intensity of internal browning, quantification of ethanol, acetaldehyde and ethyl... |

| The objective of this study was to evaluate the effect of controlled atmosphere (CA) on quality preservation of ‘Laetitia’ plums, mainly on internal breakdown, in order to determine the best CA storage conditions. Two experiments were carried out one in 2010, and another in 2011. In 2010, besides cold storage (CS; 21.0 kPa O2 + 0.03 kPa CO2), the fruits were stored under the following CA conditions (kPa O2+kPa CO2): 1+3, 1+5, 2+5, 2+10, and 11+10. In 2011, the fruits were stored under CS and CA of 1+0, 1+1, 2+1, and 2+2. The fruit stored under different CA conditions had lower respiration and ethylene production, better preservation of flesh firmness, texture and titratable acidity, lower skin red color, and lower incidence of skin cracking than the fruit... |

| ABSTRACT Flesh browning is a physiological disorder that occurs in ‘Fuji’ apples during storage, which causes considerable postharvest losses of fruit produced in Southern Brazil. This work aimed to assess the mineral attributes [Ca; Mg and K contents and the Mg/Ca; K/Ca and (K + Mg)/Ca ratios] associated with the flesh browning disorder incidence, as well as to identify which of these mineral attributes better discriminate the differences in the degree of susceptibility to flesh browning disorder in ‘Fuji’ apples stored under controlled atmosphere (CA; 1.2 kPa O2 + 2.0 kPa CO2 and 1.2 kPa O2 + < 0.5 kPa CO2; 0.5 ± 0.1 °C and 96 ± 2% RH, during an 8-month period). Apples from 2 orchards in Fraiburgo, Santa Catarina, 3 orchards in São Joaquim, Santa... |

| Este trabalho objetivou identificar os atributos minerais na casca e na polpa, relacionados à severidade de "bitter pit" em maçãs 'Fuji'. Os frutos foram colhidos em pomar comercial do município de Lages-SC, e armazenados durante quatro meses em câmara fria convencional (0±0,4°C e 90-95% de umidade relativa). Posteriormente, foram separadas em quatro lotes, de acordo com a severidade de "bitter pit": nula (0 lesão/fruto), baixa (1-2 lesões/fruto), moderada (3-4 lesões/fruto) e alta (5-16 lesões/fruto), com 15 frutos (repetições) em cada nível de severidade. Os frutos de cada lote foram analisados individualmente quanto aos teores de Ca, Mg, K e N, na casca e na polpa. Na análise univariada dos teores minerais da polpa, observou-se aumento nos níveis de K e... |

| One of the most important problems in lemon growing is the physiological disorder known as "peteca", which is characterized by causing cell dehydration and death in the albedo tissue with a subsequent necrosis of the surface zone of the fruit. This damage shows characteristics quite similar to those resulting from chilling injury in citrus fruit, where surface damage of fruit and dehydration of albedo cells also occur. Resistance to chilling injury shown by grapefruit would be related to increased proline content in the albedo (Purbis, 1981). In this study, proline content of lemons cv. "Fino" 49 from two groves, one in Curacaví (33°25.778 S - 71°02.292 W, 196 m above sea level) and the other in Mallarauco (33°94.984 S - 70°58.921 W, 269 m above sea... |

| ABSTRACT The storage of ‘Rocha’ pears under controlled atmosphere (CA) preserves fruit quality for long periods. However, inadequate CA conditions might impair ripening and lead to flesh browning. This research was carried out to assess the effects of CA with ultra-low (ULO), and low O2 (LO) associated with different CO2 levels on ripening and occurrence of flesh browning in ‘Rocha’ pears. Treatments evaluated were: pO2 = 0.5 kPa (ULO) and pCO2 < 0.03 kPa; pO2 = 1.0 kPa (LO) and pCO2 < 0.03 kPa; pO2 = 1.0 kPa and pCO2 = 1.0 kPa; pO2 = 1.0 kPa and pCO2 = 2.0 kPa; and pO2 = 1.0 kPa and pCO2 = 3.0 kPa. A completely randomized experimental design was used, with four replicates. Fruits were harvested in Vacaria, RS, and stored under five CA conditions... |
