| Abstract This work aimed to evaluate the physicochemical characteristics of different orange cultivars (Citrus sinensis) in order to identify those with potential to the consumer market and/or for processing. Five orange cultivars were evaluated: ‘Natal IAC’, ‘Natal 112’, ‘Pera IAC 2000’, ‘Pera IAC’, ‘Baianinha’ and ‘Pera Rio’, which were harvested at maturation stage considered ideal for commercialization in the “Agência Goiana de Assistência Técnica, Extensão Rural e Pesquisa Agropecuária – EMATER” experimental orchard at the municipality of Anápolis, state of Goiás. After harvesting, fruits were transported to the laboratory, selected, standardized, washed and allowed to dry. Subsequently, skin color, longitudinal and cross-sectional diameter, number... |

| Fruit growth is stimulated by different weather conditions. The aim of this study was to determine the influence of weather conditions on the physicochemical properties of pineapple guava fruit growth. Twenty trees were marked in two production areas located at different altitudes (1,800 and 2,580 m.a.s.l.), and measurements were performed every 7 days from 99 and 141 days post-anthesis to harvest at altitudes of 1,800 and 2,580 m.a.s.l., respectively. The results indicate that altitude and weather conditions greatly influence the growth and development of pineapple guava fruit, and these effects are primarily manifested in the physical characteristics of the fruit. The weight and size of the fruit at harvest are directly related to the altitude of the... |

| The objective of this study was to evaluate the effect of genetic polymorphism of kappa-casein, breed and seasonality on the physicochemical characteristics, composition and stability of milk in commercial dairy herds. A total of 879 milk and blood samples were collected from 603 Holstein and 276 Girolando cows, obtained during rainy and dry seasons. Milk samples were analyzed to determine the physicochemical characteristics, composition and ethanol stability, while blood samples were subjected to polymerase chain reaction to identify the kappa-casein genotype. The frequencies of genotypes AA, AB and BB of k-casein were respectively, 66.83, 31.84 and 1.33% for Holstein, and 71.38, 27.90 and 0.72% for the Girolando cows, respectively. The A allele was more... |

| Abstract The objective of this study was to evaluate the influence of macronutrient and boron deficiencies on physico-chemical characteristics of pineapple fruits, ‘Vitoria’ cultivar. The experimental design was a randomized complete block with eight treatments (complete solution, -N, -P, -K, -Ca, -Mg, -S and -B) and six replicates. The experiment was conducted from October 2016 to March 2018, and the variables evaluated were: fresh fruit and crown mass, fruit diameter, fruit and crown length, juice volume and mass, titratable acidity (TA), soluble solids (SS), vitamin C, juice pH and SS/TA ratio. All treatments with nutrient deficiency reduced the fresh fruit mass. In treatments -N and -Ca there was a reduction of 41.9 and 35.3%, respectively, in the... |

| The objective of this study was to evaluate the effects of foundation and leaf fertilization with micronutrients on fruit size and quality of pineapple cv. Vitória under the environmental conditions of the Baixo Acaraú irrigated perimeter in Northern Ceará State, Brazil, under two covers (bagana and black plastic) of the sandy soil of low fertility. The experimental design was a randomized split blocks one with four levels of soil dressing and four levels of foliar fertilization, with five replications. Micronutrient soil dressing was studied as FTE-12 at doses of 0, 60, 120 and 180 kg ha-1. The four levels of foliar fertilization were: LF0 (without fertilizer), LF 1 (15 leaf fertilization, using the amount of 1158.75 g Fe ha-1, 844.65 g Mn ha-1, 391.5 g... |

| ABSTRACT This study was conducted to investigate the effects of nutrient and salinity concentrations on the quality of deepflow technique hydroponic system cultivated cherry tomatoes (Lycopersicon esculentum Mill ‘Unicorn’). The conditions were: (1) control (NS-1 × nutrient Solution, Electrical Conductivity – EC: 2.5 mS∙cm–1); (2) 2 × NS (2 × NS-Double NS, EC: 5 mS∙cm–1); (3) NS + 4.23 mM NaCl (NaCl-Sodium Chloride, EC: 5 mS∙cm–1); and (4) NS + 13.70 mM Sea Water – SW (EC: 7.5 mS∙cm–1). NS + 13.70 mM SW treatment showed the lowest fresh weight loss. Visual quality as well as shelf life was the longest in NS (1 × nutrient solution) treated tomato fruits. The longest shelf life at 5 °C, 11 °C, and 24 °C were 21, 16, and 8 days, respectively, in NS (1 ×... |

| ABSTRACT Plant variables and must physicochemical properties were evaluated for the grapevine ‘Syrah’ cultivated in sequential growing seasons (summer and winter) from 2011 to 2015. The vines were trellised in vertical shoot position, grafted on Paulsen 1103, with approximate density of 5,800 plants∙ha−1. They were grown under plastic overhead cover. The experimental design was completely randomized, and the following variables were measured at the harvest: number of branches, number of clusters, cluster weight and yield, soluble solids content, pH, and titratable acidity. The highest values of yield, cluster weight, and titratable acidity were observed during the summer growing season, while the highest values of soluble solids content and pH were... |

| Abstract Nitrogen (N) and sulfur (S) are nutrients that, in addition to influencing plant growth and production, interfere with processes related to postharvest fruit quality. In the present study, N x S interaction was evaluated in the postharvest quality of tomato (Solanum lycopersicum L.). The experiment was conducted in a greenhouse using 5 dm3 capacity vessels containing a 0-20 cm layer of a dystropherric Red Latosol. A 5 x 3 factorial design was used, with combinations of five doses of N (0, 100, 200, 300 and 400 mg dm-3) and three doses of S (0, 60 and 120 mg dm-3) distributed in a completely randomized design, with four repetitions. After harvest, the attributes of fruit quality were evaluated: firmness, pH, soluble solids (SS), titratable... |

| The aim of this work was to carry out the chemical characterization and sensory analysis of strawberry fruits from cultivars Camp-dover, Dover, Camp-oso, Oso Grande, and Tudla-Milsei, grown in the southern region of Minas Gerais State. Soluble solids, titratable acidity, and the ratio between both characteristics were evaluated, in three replications. Sensory analysis was carried out by a panel of 34 non-trained assessors, recruited out of UNICENTRO students, professors, and employees. Assessors evaluated the samples for aroma and flavor using sorting-preference tests, with scores from 1 (less preferred) to 5 (most preferred). Appearance was assessed by means of a hedonic scale, from 1 (dislike very much) to 9 (like very much). Each assessor evaluated five... |

| The solubilization of inorganic phosphates by microorganisms supplies phosphates for plant nutrition and increases their growth. The solubilization of CaHPO4 (Ca-P) and AlPO4 (Al-P) by Aspergillus niger using several carbon and nitrogen sources was studied. Solubilization of Ca-P was enhanced when the carbon sources were mannitol, maltose, galactose and glucose (in that order). Galactose, sucrose and maltose were the carbon sources that enhanced the solubilization of Al-P. More extensive growth, acid production, and decrease in pH were obtained in the Al-P medium than in the Ca-P medium, however, the quantity of solubilized phosphate was 12% less. Phosphate solubilization was related to acid production, pH drop and fungal growth in the culture medium. The... |

| Hypocitraturia (HCit) is one of the most remarkable features of renal tubular acidosis, but an acidification defect is not seen in the majority of hypocitraturic patients, whose disease is denoted idiopathic hypocitraturia. In order to assess the integrity of urinary acidification mechanisms in hypocitraturic idiopathic calcium stone formers, we studied two groups of patients, hypocitraturic (HCit, N = 21, 39.5 ± 11.5 years, 11 females and 10 males) and normocitraturic (NCit, N = 23, 40.2 ± 11.7 years, 16 females and 7 males) subjects, during a short ammonium chloride loading test lasting 8 h. During the baseline period HCit patients showed significantly higher levels of titratable acid (TA). After the administration of ammonium chloride, mean urinary pH... |
