O experimento foi desenvolvido em um Neossolo Quartzarênico no município de Tianguá, Ceará, Brasil. Os tratamentos foram organizados no esquema 2 × (3 × 5), sendo a parcela principal as lâminas de irrigação (100 e 70% da ETc) e as subparcelas as combinações entre matéria orgânica (sem, esterco bovino e cama de frango) e fósforo (0, 40, 80, 120, 160 de P2O5 kg ha-1), sendo distribuídos em blocos casualizados. Avaliou-se a produção (massa média do maracujá, frutos por planta e produtividade) e qualidade pós-colheita (pH, acidez titulável, teor de sólidos solúveis e a razão sólidos solúveis/acidez titulável). A redução em 30% da lâmina de irrigação não acarretou perdas na produção, porém reduziu os sólidos solúveis com menor intensidade nas covas com matéria orgânica. Entre as fontes orgânicas, a cama de frango proporcionou maior número de frutos. O fósforo aumentou o número de frutos, produtividade e sólidos solúveis. No cultivo do maracujazeiro-amarelo em Neossolo recomenda-se utilizar cama de frango como fonte orgânica, aplicar 100 kg ha-1 de P2O5 e lâmina de irrigação de 70 a 100% da ETc.   Palavras chave: Passiflora edulis, irrigação, insumo orgânico, fósforo, produtividade.     MEDEIROS, S.

YIELD AND POSTHARVEST QUALITY OF YELLOW PASSION FRUIT UNDER WATER IRRIGATION DEPTHS, PHOSPHATE AND ORGANIC FERTILIZATION                                                           2 ABSTRACT   This study aimed to evaluate yield and postharvest quality of yellow passion fruit under irrigation depths, organic and phosphate fertilization. The experiment was carried out in a Quartz-sand Neosol located in the city of Tianguá, Ceará state, Brazil. The treatments were arranged in a 2 × (3 × 5) scheme, with main plots composed of irrigation depths (100 and 70% of ETc) and subplots composed of combinations of organic matter (without, cattle manure and chicken litter) and phosphorus. (0, 40, 80, 120, 160 of P2O5 kg ha-1), distributed in randomized blocks. The production (average passion fruit mass, fruits per plant and yield) and postharvest quality (pH, titratable acidity, soluble solids content and soluble solids/titratable acidity ratio) were assessed. The decrease by 30% in irrigation depth did not cause losses in  production, however, it reduced the soluble solids with lower intensity in treatments with organic matter. Among the organic inputs, chicken litter provided the highest number of fruits. Phosphorous fertilization increased fruit number, yield, and soluble solids. For the production of yellow passion fruit in  Neosol it is recommended to use chicken litter as organic input, with 100 kg ha-1 of P2O5 and 70 to 100% ETc irrigation depth.   Keywords: Passiflora edulis, irrigation, organic input, phosphorus, yield.

Studies related to adaptation to the environment and different conditions of water availability contribute to decision-making regarding the management of any crop to be implanted. Accordingly, this work aimed to evaluate the yield and quality of organic yellow passion fruit cultivated in a long root system in dryland conditions. The experimental design was in randomized blocks, with five treatments and four replications with four plants each. The treatments consisted of the alteration of the length of the root system, namely: T1 = 25 cm; T2 = 50 cm; T3 = 75 cm; T4 = 100 cm; and T5 = 125 cm. At 120 days after emergence (DAE), the seedlings were transplanted to the field and the following variables were evaluated: plant height (cm) and base diameter (mm) at 120 DAE; total titratable acidity (TTA), total soluble solids (TSS), Ratio (TSS/TTA); and fruit yield. The cultivation of tall seedlings with a long root system provides the maintenance of production during the dry season. The TTA, TSS, and the ratio do not change when modifying the length of the root system, although they do change with the harvest season. The cultivation of passion fruit in an organic system using plants with a long root system with an estimated length of 114 cm provides a higher fruit yield (7,472 kg ha-1) in 22 months of cultivation.

Despite the importance of passion fruit for the Brazilian fruit market, there are still many agronomic and fruit quality problems to be solved, in order to increase this crop performance. The objective of this study was to evaluate the quality of twelve genotypes of wild, sweet and yellow passion fruit, aiming to identify promising materials considering fruit quality, in Federal District, Brazil. An experiment was carried out at the Água Limpa Farm of the Universidade de Brasília (UnB) from 2016 to 2018, in a randomized block design, with 12 treatments, 4 replicates and 6 plants/plot. At the harvesting time, six fruits per plot were randomly collected for the following physicochemical analysis: fruit mass, pulp mass with and without seeds, length/longitudinal diameter, width/transverse diameter, length/width ratio, husk thickness, predominant color of the pulp (L*, C*, h*), number of seeds, seed size, total soluble solids content, total titratable acidity, total soluble solids/total titratable acidity ratio and pH. High heritability values ​​and relation of genetic/environment variation coefficients ratio were observed for most of the characteristics evaluated. The genotypes of yellow passion fruit MAR20#21 P2 x FB 200 P1 R2 and MAR20#19 ROXO R4 x ECRAM P3 R3 showed the best characteristics of fruit mass and pulp mass with seed. All the genotypes studied showed values ​​of total soluble solids above 11ºBrix. Positive and significant correlation was observed between fruit mass and length/width ratio, indicating that oblong fruits have higher fruit mass.

ABSTRACT Studies with nitrogen and potassium in yellow passion fruit cultivars with high yield potential are scarce in semiarid regions. The aim of this study was to evaluate the influence the N and K doses on productivity and fruit quality of different passion fruit cultivars in irrigated conditions in the northern of Minas Gerais state. The study was installed at experimental farm located in Janaúba-MG. This area was located at 15º 47’ S and 43º 18’ W, 516 m above sea level. The experiment was in completely randomized block with four replications, arranged in 4 x 6 factorial design consisting of four Passion Fruit cultivars (BRS Sol do Cerrado, BRS Ouro Vermelho, BRS Gigante Amarelo, IAC 275) and six N and K doses, which corresponded to 0-0, 50-125, 100-250, 150-375, 200 -500 and 250-625 kg ha-1 yr-1 of N and K2O, respectively. BRS Gigante Amarelo and BRS Sol do Cerrado cultivars showed higher productivity. Total fruit yield and average fruit weight were higher for BRS Sol do Cerrado and IAC 275, BRS Gigante Amarelo and BRS Ouro Vermelho cultivars, respectively. IAC 275 showed the highest pulp yield and along with BRS Sol do Cerrado, showed the higher soluble solids/titratable acidity ratio. BRS Sol do Cerrado, BRS Gigante Amarelo and IAC 275 cultivars showed higher pulp productivity, indicating that they are more promising for passion fruit juice industry.

Pitaya is a non-climacteric fruit that has white or red flesh with numerous small, black seeds. It has a high moisture content; however, water loss during handling and storage negatively affects the fresh weight, firmness and appearance of the fruit, decreasing market value. Application of compatible postharvest coatings has been shown to benefit postharvest quality of many crops. The objective of this study was to evaluate the effect of two commercial coatings on weight loss and quality of pitaya during storage. Pitaya fruit were commercially harvested and sorted for uniformity of size and freedom from defects. Fruit were briefly immersed in either a vegetable oil-based coating (VOC; Sta-Fresh® 2981) or a carnauba-based coating (CC; Endura-Fresh™ 6100) according to manufacturer’s recommendations. Fruit immersed in tap water served as a control. Fruit were fan-dried at room temperature for 20 min, then stored at 7 °C with 85% relative humidity (RH) and evaluated for selected physical quality parameters each 5 days during 20 days. After each evaluation, fruit were peeled and frozen for later analysis of soluble solids content (SSC), total titratable acidity (TTA); on day 15 fresh samples were evaluated by an untrained consumer sensory panel. CC prevented exocarp shriveling for 15 days of storage, compared to uncoated pitaya (16.3% area affected); shriveling in VOC was intermediate and not significantly different from the other treatments. Mesocarp firmness remained constant throughout 15 days of storage regardless of treatment. Fruit exocarp h* angle increased slightly by day 20, becoming slightly less red, and there were no negative treatment effects for the other quality factors measured: SSC (11.33%), TTA (0.25%), weight loss (5.5%) or sensory evaluations (appearance, flavor, texture, firmness, and juiciness). After 20 days storage, appearance for fruit from all treatments was rated unacceptable due to development of anthracnose lesions. It was concluded that both CC and VOC maintained quality of pitaya for 15 days at 7 °C and 85% RH by delaying exocarp shriveling.

‘Red Globe’ table grapes are large, edible, seeded fruit with firm flesh that tastes good, but can have poor postharvest shelf-life. This study was conducted to explore the effects of products of Lactobacillus delbrueckii subsp. bulgaricus strain F17 and Leuconostoc lactis strain H52 on ‘Red Globe’ table grapes for the enhancement of shelf-life and improvement of grape quality characteristics during postharvest storage. Strains F17 and H52 were isolated from traditional fermented yak milk obtained in the Qinghai–Tibetan Plateau. Samples from untreated and treated grapes were analyzed for physicochemical, biochemical, and microbiological properties (weight loss, decay rate, pH, total soluble solids content, titratable acidity, total phenols, sensory evaluation, and microbial growth) for 20 days. The results demonstrated that supernatants from both strains significantly reduced weight loss, decay rate, aerobic mesophilic bacteria, and coliform bacteria counts; delayed maturity and senescence of table grapes; and reduced titratable acidity and total phenols. However, the supernatant of strain F17 was more effective and resulted in better sensory evaluations and had a significant inhibitory effect on yeast and molds by day 5. Meanwhile, the supernatant from strain H52 had a significant inhibitory effect on fungi over the whole storage period. In addition, the results of the Pearson correlation analysis suggested that weight loss, decay rate, total soluble solids content, and microorganisms were highly correlated with the sensory evaluation data and quality of postharvest grapes when treated with the products of strain F17. On the basis of these data and sensory organoleptic qualities, the supernatant containing products from strain F17 had the best potential as a biopreservative to improve the postharvest quality of ‘Red Globe’ table grapes.

Irrigation is a practice widely used in fruit production in the Brazilian Northeast region, including in the papaya crop in order to increase their productivity. For the purpose of knowing the productive potential of papaya hybrid irrigated, an experiment was carried out in order to evaluate the performance of a papaya hybrid under different irrigations depths. Four irrigation depths (50, 75, 100 and 125% of ETo) were tested and the reference evapotranspiration was calculated by the Penman-Monteith model. The hybrid papaya used was UENF/Caliman 01, which was planted in single rows, spaced 4 x 2m from each other, and irrigated by dripping. The experimental design in randomized blocks was used with six replications and three plants per plot. The following variables were evaluated: transversal diameter, longitudinal diameter, pulp thickness, external and internal appearances, soluble solids, titratable acidity, pulp pH and soluble solids/titratable acidity relation. The higher transversal and longitudinal diameters of the fruit were obtained applying an irrigation depth of about 108% of evapotranspiration. The UENF/Caliman 01 hybrid can be cultivated in the semiarid region of the State of Paraiba, Brazil, with replacement rate of 100% ETo, without compromising the quality of the fruits.

This study aimed to evaluate postharvest quality of Tommy Atkins mangoes treated with starch cassava and chitosan based coatings. Mango fruits were collected at physiological maturity. After cleaning, weighing and identification, fruits were submitted to the respective treatments and stored for 35 days in the Laboratório de Tecnologia de Alimentos, with weekly evaluations under refrigeration 13±1 ºC and 90±5% RH. The experiment was conducted in a completely randomized design, in factorial scheme with four treatments: control, cassava starch (CS), chitosan (CH), and cassava starch/chitosan (CS/CH) at a concentration of 2%, and six storage periods (0, 7, 14, 21, 28 and 35 days) with four replications. Fruits were evaluated in: appearance, weight loss, external color: luminosity and ΔE, pulp firmness, titratable acidity, soluble solids content, starch, total soluble sugars, reducing sugars and sucrose. Data were submitted to analysis of variance using SISVAR software and compared by Scott-Knott test at 5% of probability. It was observed a reduction in appearance, pulp firmness, titratable acidity, starch and reducing sugars and increase in weight loss, luminosity, ΔE, soluble solids, total soluble sugars and non-reducing sugars during storage. CS/CH coated fruits reported higher notes of appearance, lower weight loss and maintained color. Quality of physicochemical attributes: soluble solids, starch, total soluble sugars, reducing sugars and non-reducing sugars were strongly retarded.

`Marsh' and `Ruby Red' grapefruit (Citrus paradisi Macf.) were harvested in Florida during Oct. and Nov. 1990, degreened in an ethylene chamber, exposed to vapor heat (VH) treatment (43.5 ± 0.1C for ≈240 min), and evaluated for deterioration in quality and development of injury after various storage regimes. Symptoms of aging averaged 6% and 8% of the surface on `Ruby Red' and `Marsh' fruit, respectively, and the VH treatment had reduced the incidence of aging by 45% after 5 weeks of storage (4 weeks at 16C plus 1 week at 21C). Total decay, mostly stem-end rots (Diplodia spp. and Phomopsis spp.), remained relatively low (≈5%) in both treated and nontreated fruit after 5 weeks of storage. The VH treatment had little effect on change in peel color during treatment or subsequent storage. After the final inspection, `Marsh' fruit was higher in total soluble solids and titratable acidity than `Ruby Red' fruit, but these quality indicators and pH were not affected by the VH treatment. VH treatment did not adversely affect the quality of `Marsh' or `Ruby Red' grapefruit harvested early in the season; hence, VH should be considered as a viable quarantine treatment for Florida grapefruit.

Abstract The aim of this work was to evaluate the effect of irrigation and deep planting of tall yellow passion fruit seedlings in the organic system on fruit quality and productivity. A randomized complete block design with 2x4 subdivided plots, with 8 treatments and 4 blocks was used, with irrigated and rainfed systems being plots and 4 planting depths (0.20 m, 0.40 m, 0.60 m and 0.80 m) subplots. Seedlings aged 90 days and 2 m in height were used. Before planting, all stem leaves were removed from seedlings to be buried and to IBA at concentration of 4,000 mg kg-1 was applied. The number of fruits per plant, average fruit mass and total productivity and of 1st and 2nd crops, as well as total soluble solids (TSS), total titratable acidity (TTA), ratio (TSS/TTA), commercial and equatorial diameter classification were estimated. Irrigated planting at depths of 0.20 m and 0.40 m was more productive in the first crop, but there was no difference in the total productivity and in the second crop. Neither irrigation nor plant depth altered the chemical quality of fruits and commercial classification.

Over three years the postharvest quality of 'Marli' peaches harvested from the integrated (IFP) and conventional production (CFP) systems was evaluated. The peaches were harvested from commercial orchards of Prunus persica at two locations close to the city of São Jerônimo, RS, Brazil, and stored at 0.5°C for 10, 20 or 30 days. The peaches were evaluated at harvest, at retrieval from storage and after ripening periods at 20°C. No differences in fruit weight losses were determined. Decay incidence was low, and no differences were detected amongst systems in both 2001 and 2002 seasons, but in the 2000 season CFP peaches were more decayed. Flesh firmness of peaches from the IFP system were greater than CFP fruits in the years 2000 and 2001. In 2002, firmness changed little during storage and ripening. Peaches from the IFP in 2000 had higher titratable acidity and lower soluble solids. In the 2000 season, flesh browning was observed in decayed fruits, always at ripening after 20 or 30 days of cold storage Chilling injuries such as browning, woolliness and leatheriness ocurred in 2002. There were no differences amongst systems related to peach quality.
