“…, close to those found byJung et al (2007a, b), in 36 crosses of P. alata, which was 30.26%;Alves et al (2012a) in mature fruits of P. alata after 30.6 days of anthesis, the proportion of 74.10% of pericarp (peel), 24.46% of pulp and 3.14% of seeds, while in P. edulis f. flavicarpa, Negreiros et al (2008) observed pulp yield between 27.65 and 45.83%. Like the physical characteristics, the chemicals are very important in a series of factors such as the conservation of the pulp and the amount of sugars to be added to the juice.…”

“…The total acidity of fruits of genotypes 2, 4, 7, 8, 11-13, 17-22, 25, 27 and 31 stands out in the cluster of higher means, with values ranging from 5.71 to 7.48% (Table 2). Freitas et al (2006) working with the same species found 1.70 g of citric acid / 100 mL, and according to Alves et al (2012a) For both the industry and the fruit market in natura, the soluble solids (SS) content must be high, and the higher the SS content the lower the quantity of fruits required for the juice concentration (Negreiros et al, 2008). The genotypes 15; 17; 22 and 24 presented the lowest levels of SS,17,20;17.77;17.85 and 16.15 °Brix,respectively, whose values are below the mean that was 19.67 ° Brix (Table 2).…”

Physical and chemical characterization of sweet passion fruits genotypes in Sao Mateus, Espírito Santo State, Brazil

et al. 2018

In Brazil 95% of the passion fruit marketed comes from the species Passiflora edulis f. flavicarpa (yellow passion fruit), the remainder are Passiflora edulis f. edulis (purple passion fruit) and Passiflora alata (sweet passion fruit), considered market niches. Because of the wide genetic variability the genus Passiflora, it is of fundamental importance to identify superior genotypes to improve the quality of fruit for the fresh market. The objective is to analyze the physical and chemical characteristics of the fruits of 33 genotypes P. alata Curtis, evaluated in a randomized complete block design with two replicates of four plants, from native matrices, located at the experimental farm of the University Center of the North of Espírito Santo, Federal University of Espírito Santo, in the Northern Region of the state of Espírito Santo, São Mateus -ES. Thirty-two mature fruits were collected in each replicate, eight per plant and the following characteristics were analyzed: fruit weight (g); equatorial and polar diameter of fruit (cm); peel thickness (mm); mass of the pulp (g); pulp volume (mL); pulp yield (%); number of seeds per fruit, pH; soluble solids (SS); titratable acidity (TA) and ratio (SS/TA). There is a wide genetic variability among P. alata genotypes as to the traits assessed. Genotypes 4, 6, 8, 11, 15, 18, 21, 25 and 26 stood out among the rest, and is therefore recommended for new plantings and future breeding programs.

“…We also determined the minimum critical point (PC min ), which represents the moment in the accumulation curve in which expressive gains in dry matter start to occur, and the maximum critical point (PC max ), which represents the moment when the accumulation of the components begins to stabilize, as previously described (Alves et al, 2013):…”

Tomato growth analysis across three cropping systems

et al. 2017

The objective of this work was to analyze the growth of the Upiã tomato cultivar in the Vertical, Crossed Fence and Viçosa cultivation systems, in order to obtain explanations for the productive gains achieved in the Viçosa system. The experiment was conducted in Viçosa, Minas Gerais State, Brazil, from August 21st to December 5th, 2012, in the scheme of subdivided plots, being the plots represented by the cultivation systems: Vertical, using tape, 1.0×0.5 m spacing; Crossed Fence, staked with bamboo, 1.0x0.5 m spacing; and Viçosa, using tape, 2.0x0.2 m spacing. The subplots were composed by the sampling times of the plants: 15, 30, 45, 60 and 75 days after transplanting. The experimental design was in randomized blocks, with four replications. Each plot was composed by three lines of 10 plants, making a total of 30 plants per plot, being evaluated the four central plants of each plot. We evaluated the dry matter of leaves (MSF), stem (MSC), inflorescences (MSI), fruits (MSFr) and total (MST). Using the foliar area index, measured by digital scanners and the previously obtained dry masses, we determined the physiological growth indices: foliar area index (IAF), specific foliar area (AFE), relative growth rate (TCR), and net assimilation rate (TAL). The Viçosa system altered the growth pattern of the tomato, quantified by the growth analysis, in comparison to Crossed and Vertical Fences. The prolongation of the second growth phase for the dry matter of fruits could possibly explain the productive gains obtained in the Viçosa system. Additional studies are required in order to clarify the relationship between the duration of the second phase of fruit dry matter growth, the physiological indexes AFE, IAF and TAL with the size and fruit yield of the tomato.

“…Populations with one and six plants per pit did not differ in the titratable acidity of fruits between harvests, but reductions were occurred from the first to the second harvest in the arrangements with two, 4.5 to 3.3% citric acid (-27%), and three plants, from 3.7 to 3.1% citric acid (-16%) ( Table 2). The citrus acid is rapidly accumulated after the physiological maturity of the fruit and it is degraded during ripening (Vianna-Silva et al, 2010;Botelho et al, 2019) to meet the respiratory demand of this climacteric fruit (Alves et al, 2013 ). According to Cavichioli et al (2008) and Vianna-Silva et al (2008 temperature is a preponderant factor in the concentration of citric acid.…”

“…On average it was 1.4 °Brix more in cultures with one and three plants per pit ( Table 2). The soluble solids increase during the growth/maturation of passion fruit (Coelho et al, 2010;Vianna-Silva et al, 2010;Alves et al, 2013), and it is also one of the most influenced physical-chemical atributes by the harvest season. The highest (16.5 °Brix) and lowest (12.6 °Brix) soluble solids values were in the fruits of the second crop in the arrangement with one plant and in the first crop of the crop with six plants per pit, respectively.…”

Effect of population and organomineral fertilization on physico-chemical quality of fruits of Passiflora edulis cv. Guinezinho

et al. 2020

The phyto-technical management of crops, such as the conduction system, spatial arrangement of plants and mineral and organic fertilization are pre-harvest agronomic factors that can alter fruit quality. Therefore, this research was developed to evaluate physico-chemical attributes of yellow passion fruit as a function of population arrangement and organomineral fertilization. The experiment was carried in Entisol with free-sand texture under tropical climate with dry summer. The treatments were obtained from the combination of doses of nitrogen (92, 119, 183, 248 and 275 kg ha-1) and soil organic matter (1.3, 1.8, 2.9, 4.0 and 4.5%), through Central Box Compound, plus four additional treatments to study the effect of the number of plants per pit. The evaluations were carried on seven and ten months after the transplanting of the seedlings. A randomized block design with three replications was used. The fruits were harvested at the beginning of the yellowing of the bark and evaluated in the pulp: pH, total titratable acidity (TTA), total soluble solids (TSS), reducing sugars, non-reducing sugars and total sugars, ascorbic acid, TSS/TTA ratio, electrical conductivity and humidity. The harvesting season changed the physico-chemical properties of the passion fruit pulp and interfered with the effects of plant management and fertilization on the quality of passion fruit. For the production of the best quality passion fruit we may cultivate one, two or three plants per pit. With three plants per pit it is recommended to apply 180 kg ha-1 of nitrogen annually and raise the soil organic matter to 4%.
