| Fruits that go through processes of sanitation, peeling, cuttingand packaging,to be consumed soon afterwards, are called minimally processed fruits.Since fruit consumption is important in the human diet, consumers have looked for practicality in both preparation and consumption, a situation that includes minimally processed food. However, minimal processing can damage plant tissues, mainly by pulp browning and by accelerating changes in natural characteristics of the product. This study aimed at minimizing changes in minimally processed sliced peaches by immersing them in solutionswhich contained preservatives.The experiment was a completely randomized design in a 5x3 factorial scheme (5 anti-browning agents x 3 storage periods), with 4 trays per... |

| Para pessegueiros produzidos na região sul do Brasil ainda são escassas as informações sobre a influência da adubação potássica sobre a qualidade dos frutos. Deste modo, o presente trabalho teve como objetivo avaliar os atributos físico-químicos e compostos bioativos dos frutos de pessegueiros submetidos a diferentes doses de potássio aplicadas no solo por três safras consecutivas. O experimento foi realizado estudando a cultivar Sensação em um pomar comercial no município de Morro Redondo, RS ? Brasil, durante as safras de 2016, 2017 e 2018. Os pessegueiros da cultivar Sensação foram adubados com potássio (K) nas doses de 0, 40, 80, 120 e 160 kg ha-1 de K2O na forma de cloreto de potássio, aplicadas na superfície do solo. Após a colheita foram... |

| Para frutíferas de caroço o potássio (K) está relacionado com a qualidade dos frutos. O objetivo deste trabalho foi avaliar diferentes doses de adubação potássica nas características físico-químicas e compostos bioativos de frutos de pessegueiros ?Esmeralda?. O experimento foi desenvolvido em pomar comercial no município de Morro Redondo, Rio Grande do Sul, Brasil, entre as safras de 2014 e 2017. As doses de potássio aplicadas foram 0, 40, 80, 120 e 160 Kg K2O ha-1. Avaliou-se: coloração da polpa, firmeza da casca e da polpa, sólidos solúveis, pH, acidez titulável, relação SS/AT, compostos fenólicos totais, carotenoides totais e atividade antioxidante. O aumento das doses de K reduziu o teor de compostos fenólicos e a atividade antioxidante nos pêssegos... |

| Thinning is a cultural practice that leads to balance between fruit yield and quality. It is carried out in a short period of time and requires qualified workforce, whose shortage ends up increasing costs. This study aimed at evaluating the thinning effect of metamitron on peach trees at different periods of time after bloom. The experiment was carried out in a commercial orchard of ?Sensação? peach trees located in Morro Redondo, Rio Grande do Sul (RS) state, Brazil, in 2015-2016 crops. Treatments were the application of 200 mg L-1 metamitron, 20, 30, 40, 50 and 60 days after full bloom (DAFB), and manual thinning 40 DAFB. Fruit abscission, effective fructification, period of manual and chemical thinning, number of fruits and yield per plant, mean fruit... |

| Nitrogen, which is the primary nutrient peach trees need, may affect their fruit quality. Thus, this study aimed at evaluating the effect of nitrogen fertilization on two genotypes of peach trees, regarding their fruit quality, in three consecutive crops. The experiment was carried out in the experimental area that belongs to the Embrapa Clima Temperado, located in Pelotas, Rio Grande do Sul (RS), Brazil, from 2016, 2016, 2017 and 2018. Four doses of nitrogen (0, 60, 120 and 180 Kg ha-1) and two peach tree genotypes (?Cascata 1513? and ?Cascata 1067?) were used. For the fruit, we evaluated epidermis color, pulp firmness, epidermis firmness, soluble solids concentration, titratable acidity, concentration of total phenolic compounds, anthocyanins and... |

| Passion fruit production in Brazil is concentrated in tropical regions, however, recently production has expanded to regions with temperate climate. Cultivar performance in different climate and soil can lead to variation in the contents of bioactive compounds in the juice and rind of the fruit. This study characterized the bioactive content of passion fruit rind and juice of six passion fruit genotypes (?Catarina Roxo?,?Catarina?, ?Urussanga?,?BRS Gigante Amarelo?, ?BRS Rubi do Cerrado?, and?BRS Sol do Cerrado?) cultivated in southern Brazil. Phenolic, flavonoid, anthocyanin, carotenoid, and ascorbic acid contents and the antioxidant potential of each fruit portion from each genotype were evaluated. Fruit composition varied with genotype and evaluated... |

| Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill. Pecan branches were collected from twelve 9-yearold cultivars ? Success, Shoshoni, Farley, Elliott, Mohawk, Jackson, Desirable, Barton, Importada, Shawnee, Choctaw and Melhorada ? in two orchards located in Canguçu, Rio Grande do Sul (RS) state, Brazil, in 2017 and 2018. Treatments consisted in exposing branches to 0, 250, 500, 750 and 1,000 chill hours in a cold chamber (4.0 ± 0.5 °C) and then taking them to the germination chamber (25 ± 0.5 °C and... |
