Abstract Passiflora cincinnata Mast. or Caatinga passion fruit is widely cultivated in the northeastern semi-arid regions of Goiás, Minas Gerais, and Bahia. The system of cultivation and field management of the Passiflora species affects the physicochemical quality of its fruits. In this study, we evaluated the chemical and physico-chemical characteristics of the fruits of 2 progenies (CPEF2220 and CBAF2334) of P. cincinnata species using the vertical and horizontal trellis system. Fruits were collected from the plants at their physiological maturation stage and tested for the fruit skin color and texture and the pH, total soluble solids, titratable acidity, pulp acidity ratio, and the contents of flavonoids, anthocyanins, and polyphenols in the seedless fruit pulp. The experimental design was completely randomized in a 2 x 2 factorial scheme (progenies x conduction system) performed in 3 replications using 4 plants in each. The analysis of variance and the means were compared using the Tukey’s test at 5% probability. The results revealed that the CBAF2334 fruits presented with greener pigments and greater flavonoids. The fruits were characterized by their green color with some yellowish nuances and a low color saturation in both the progenies. The conduction system was not found to affect the physical and physicochemical characteristics as well as the anthocyanin and polyphenol contents of the studied species. The fruits of plants cultivated on vertical trellis presented with 56.73% more flavonoid content than those cultivated on horizontal trellis.

The umbuzeiro is a native Brazilian semi-arid plant with great agroindustrial potential. The characterization of the fruit, as well as the development or improvement of technologies for value aggregation are fundamental for its conservation, dissemination and culinary expansion. The objective was to characterize physically and chemically fruits of umbu and to define the access with greater commercial potential. A completely randomized design was used, with 10 replications, in a total of 4 accessions of umbuzeiro. The fruits were selected prioritizing uniformity of fruit size and maturation stage. Fruit peel color was analyzed; diameter and length; mass of the fruit, the bark, the pulp and the seed; firmness of the fruit, soluble solids contents; pH; titratable acidity and solids/acidity ratio. The values of the pulp yield and the technological index were determined. Significance was verified for all variables, except for soluble solids and pH. The average value of the titratable acidity was 1.3 mg of citric acid 100 mL-1 of juice. The diameter of the fruits varied between 4.0 and 4.5 cm. Fruit mass varied from 33.00 to 43.62 g and access to EPAMIG-C06 was the heaviest. The accesses EPAMIG-C06 and EPAMIG-C18 presented the highest technological index. Based on the results, it was concluded that the accesses present potential to the pulp industry due to the size and characteristics of the fruits. The umbu accesses under study presented small variation for solubility and pH. For in natura consumption and/or processing, the access EPAMIG-C06 stands out due to attributes of commercial interest.

Bell Peppers

The bell pepper presents alterations in its composition and its properties with the process of senescence during ripening. These composition and textual factors are part of the quality of the fruit and therefore of the selection. This permits the correct knowledge of the factors necessary for post-harvest measures, so that they can be adequately applied. The aim of this study is to analyze the 'Zarco HS' yellow pepper at various levels of ripeness taking into account its physico-chemical properties (titratable acidity, pH, total soluble solids, water content, and ascorbic acid), in order to understand this behavior during the ripening process. Bell peppers were separated based on their yellow percentage, which varied from 0% to 100%, and for each percentage five fruits were chosen as replicates. They were compared to 0%, 25%, 50%, 75% and 100% levels of ripening, due to the difficulty of the methodology in identifying the smaller differences between coloring. The 'Zarco HS' yellow bell pepper presents greater levels of soluble solids and lower levels of malic acid as the percentage of external yellow coloring increases. The yellow bell peppers, especially when totally yellow, represent an important source of vitamin C.

Coconut water is highly consumed for refreshment due to its nutritional value. However, its nutritional value varies according to the ecotype and stage of maturity of ecotype. In order to identify best ecotypes with high nutritious value, a physico-chemical composition of ten (10) ecotypes was performed at earlier stage of maturity (3 months). The measured parameters were: coconut height, mass of water, total sugar content, soluble sugar content, protein, titratable acidity and pH.  The obtained results showed that all parameters vary from one ecotype to another. All coconut ecotypes contain water slightly acid with a pH value less than 7.  Furthermore, there is no relationship between physical and biochemical parameters. However, within characterized ecotypes, Ecotype_2, appeared to have the best biochemical composition with a significant amount of water. This study provided important informations related to physico-chemical characteristics of coconuts ecotypes found in the coastal zone.

ABSTRACT This study aimed to evaluate the physico-chemical composition of native fruits of the Ceará coast at different development stages. The fruits of ‘guajiru’, ‘manipuçá’, ‘murici-pitanga’ and ‘murta’ were collected during the year 2014, and the following evaluations were made: total soluble solids, total titratable acidity, pH, total soluble solids and titratable acidity ratio. A completely randomized design was used, with 5 or 6 treatments, depending on the maturation stage and 4 replicates. For total soluble solids, ‘murta’ obtained a minimum of 2.6 °Brix in stage 1 and ‘manipuçá’ obtained maximum of 24.53 °Brix in stage 5. For the total titratable acidity, ‘guajiru’ showed minimum of 0.09% in stages 3 and 4, and ‘murici-pitanga’ showed maximum of 3.29% in stage 6. ‘Murici-pitanga’ had minimum pH of 3.44 in stage 5 and ‘guajiru’, maximum pH of 5.9 in stage 2. For total soluble solids and titratable acidity ratio, ‘murici-pitanga’ exhibited a minimum of 3.25 in stages 1 and 3, and ‘guajiru’ showed maximum of 141.11 in stage 4. It was concluded that ‘guajiru’ and ‘manipuçá’ fruits reached physiological maturity in stage 3, whereas ‘murici-pitanga’ and ‘murta’ fruits reached in stage 4; thus, these are the ideal stages for fruit harvest.

ABSTRACT This work evaluated the effects of ionizing radiation on the physico-chemical and sensory characteristics of the potato cultivar Ágata (Solanum tuberosum L.), including budding and deterioration, with the end goal of increasing shelf life. For this, four groups of samples were harvested at the maturation stage. Three of them were separately exposed to a Co-60 source, receiving respective doses of 0.10, 0.15 and 2.00 kGy, while the non-irradiated group was kept as a control. All samples were stored for 35 days at 24 °C (± 2) and at 39% relative humidity. The following aspects were evaluated: budding, rot, loss of weight, texture, flesh color, moisture, external and internal appearance, aroma, soluble solids, titratable acidity, vitamin C, protein, starch and glucose. The results indicated that 0.15 kGy was the most effective dose to reduce sprouting and post-harvest losses, under the conditions studied.

Abstract This study aimed to evaluate the flowering period and the physicochemical characteristics of peaches, aiming to find those most promising for the diversification of the peach crop in the Metropolitan Region of Curitiba, Paraná State. We evaluated 8 selections and three cultivars in Porto Amazonas and 10 cultivars in Araucaria for flowering period, fruit set, diameter and height of fruit, average fruit weight, the skin color, soluble solids (SS), titratable acidity (TA), ratio SS/ TA, hydrogen potential (pH). The flowering period occurred between late June and late September ranging from 16 to 25 days. The fruit set rate was greater than 50% for ‘Cascata 1513’, ‘Cascata 1429’, ‘Cascata 1577’, ‘Cascata 1743’ and for all cultivars in Araucaria. There were significant differences for the other variables assessed. It was concluded that in Araucária, ‘Charme’ and ‘Chimarrita’ are good planting options, have the same duration of the cycle (111 days), being ‘Charme’ a little later. Besides these, ‘Douradão’ and ‘Rubimel’ have good fruit size, moderate acidity and best SS/TA ratio, being earlier than the previous ones. ‘PS 25399’ is the earliest and showed reddish epidermis and great consumer interest. In Porto Amazonas, selections and cultivars tested produced little fruit of small size, being required more studies to be recommended in these area.

Os atributos físicos e químicos da acerola podem sem influenciados por vários fatores: genótipo, localização do pomar, tratos culturais empregados nas plantas, índice pluviométrico, irrigação, exposição à luz solar, estádio de maturação dos frutos e época de colheita. O presente trabalho avaliou características químicas e físico-químicas de frutos de diferentes genótipos de aceroleira em duas épocas de colheita. A primeira época no período de fevereiro a março de 2014, e a segunda época de dezembro de 2014 a janeiro de 2015. Os materiais genéticos avaliados foram Olivier, BRS 237 - Roxinha, BRS 236 - Cereja, BRS 238 - Frutacor, BRS 235 - Apodi, Waldy – CATI 30 e Okinawa. O delineamento utilizado foi o inteiramente casualizado (DIC) em esquema fatorial, com 7 cultivares em 2 épocas de colheita, totalizando 14 tratamentos, e a repetição sendo 500 g por amostra de frutos maduros para cada genótipo de aceroleira representado por oito plantas em fase de produção e com oito anos de idade. Avaliaram-se os seguintes atributos físico-químicos: pH e sólidos solúveis (°Brix), e químicos: ácido ascórbico, e acidez titulável (expressa em g de ácido cítrico 100 g-1 de polpa). Também foi determinada a relação °Brix / Acidez titulável. Nas duas épocas de colheita avaliadas, a composição da acerola é mais influenciada pelo genótipo que pelas condições climáticas de precipitação e temperatura do ambiente. Todos os clones de aceroleira atendem a legislação brasileira vigente quanto à qualidade de polpa de fruta de acerola.Palavra-chave: Malpighia emarginata Sessé e Mociño ex DC, qualidade, fruticultura tropical. COMPOSITION OF THE ACEROLA OF DIFFERENT GENOTYPES IN TWO SEASONS OF HARVEST ABSTRACT:The physical and chemical attributes of acerola can be influenced by several factors: genotype, orchard location, crop management, pluviometric index, irrigation, exposure to sunlight, fruit maturation stage and harvest season. The present work evaluated the chemical and physical-chemical characteristics of the acerola of different genotypes at two harvest seasons. The first time in the period from February to March 2014, and the second time from December 2014 to January 2015. The genetic materials evaluated were Olivier, BRS 237 - Roxinha, BRS 236 - Cherry, BRS 238 - Frutacor, BRS 235 - Apodi, Waldy - CATI 30 and Okinawa. The design was a completely randomized design in a factorial scheme, with 7 cultivars in 2 seasons of harvest, totaling 14 treatments, and the repetition being 500 g per sample of mature fruits for each genotype of acerola represented by eight plants in production and eight years of age. The following physico-chemical attributes were evaluated: pH and soluble solids (° Brix), and chemicals: ascorbic acid, and titratable acidity (expressed in g of citric acid 100 g-1 of pulp). The ratio ° Brix / Titratable acidity was also determined. In the two evaluated harvest periods, the composition of the acerola is more influenced by the genotype than by the climatic conditions of precipitation and temperature of the environment. All clones of acerola are in compliance with the Brazilian legislation in force regarding the quality of fruit pulp of acerola.Keywords: Malpighia emarginata Sessé e Mociño ex DC, quality, tropical fruticulture. DOI:

ABSTRACT Passiflora cincinnata Mast. (caatinga passion fruit) has acidic fruits with a peculiar flavor, green color when ripe and a low percentage of abscission making it difficult to identify the point of harvest. In order to verify the harvest period in two populations of P.cincinnata, flowers were marked in anthesis and after six periods the fruits were harvested. This study evaluated fruit mass, seeds and pulp mass, fruit dimensions and shape, percentage of water, color and texture of skin, volume, color and pulp yield, pH, soluble solids (SS), titratable acidity ratio, polyphenol content, flavonoids and anthocyanins. The assay was designed in a completely randomized design in a factorial arrangement (2x6), with two populations (CPEF2220 and CBAF2334) and six harvest periods (20, 40, 60, 80, 100 and 120 days after anthesis - DAA) with four repetitions. There was a reduction in thickness (43.1%) and percentage of water in the skin (9.3%), pH (40.1%), ratio, polyphenols content and pulp luminosity (brightness). There were increases in pulp mass and volume, seed mass, pulp mass yield in relation to the fruit (72%), and SS titratable acidity (44.9%) in CPEF2220 and equality between populations in fruit shape, pulp color, thickness and skin color (luminosity and ºhue), pH and polyphenols. Although after 100 DAA there were higher yields, between 60 and 80 DAA it was possible to identify characteristics of SS, pH, titratable acidity, mass, volume and pulp yield related to ripe fruits, allowing harvesting after 60 DAA.
