Among the many species of native fruit of Brazil that have been little explored, there is Myrciaria floribunda (also known as rumberry, cambuizeiro, or guavaberry), a species with significant variability, which has fruits of different colors (orange, red, and purple) when ripe. The physical-chemical characteristics evaluated were fruit weight (FW), seed weight (SW), pulp weight (PW), number of seeds (NS), longitudinal diameter (LD), transverse diameter (TD), format (LD/TD), hydrogen potential (pH), soluble solids (SS), titratable acidity (TA), and ratio (SS/TA); further, the volatile organic compounds (VOCs) of nine accesses of rumberry orchards were identified. The averages of the variables FW, SW, PW, NS, LD, TD, shape, and firmness were 0.76 g, 0.22 g, 0.54 g, 1.45, 10.06 mm, 9.90 mm, 1.02, 2.96 N, respectively. LD/TD data showed that the fruits have a slightly rounded shape (LD/TD = 1). The averages for pH, SS, TA, and SS/TA were 3.74, 17.58 Brix, 4.31% citric acid, and 4.31, respectively. The evaluated parameters indicated that the fruits can be consumed both in natura and industrialized, with the red-colored fruits presenting a good balance of SS/TA, standards demanded by the processing industries. Thirty-six VOCs were identified, with emphasis on the sesquiterpenes. Caryophyllene (21.6% to 49.3%) and γ-selinene (11.3% to 16.3%) were the most predominant compounds in rumberry fruits.

ABSTRACT Characterization of cocoa clones produced in the semiarid region is necessary to enlarge the database about these implanted clones and thus enhance the quality of their by-products. Therefore, this study aims to evaluate physical, chemical, and physicochemical characteristics of the CCN 51, CEPEC 2004, CEPEC 2005, and PS 1319 clones, produced in the region of Vale do Jaguaribe in the state of Ceará (Brazil), and to suggest food processes or products for them. The clones were evaluated according to their physical traits (total fruit mass, rind, pulp, seeds, and placenta and pulp with seeds), fruit transverse diameter (FTD), fruit longitudinal diameter (FLD), the ratio FTD/FLD; rind external thickness (ERT), rind internal thickness (IRT), the ratio ERT/IRT, number of seeds, seed thickness, seed transverse diameter (STD), seed longitudinal diameter (SLD), and the ratio STD/SLD, yield, pulp color, chemical traits (humidity, lipids, proteins, ashes, crude fiber, and carbohydrates), and physicochemical traits (titratable acidity, pH, soluble solids, and reducing sugars) were evaluated. The CCN 51 and CEPEC 2005 clones are the most suitable for the process of cocoa fermentation. For desserts, jams, pulp, and nibs for fat-restricted diets, the most suitable clones are CCN 51, CEPEC 2005, PS 1319 and CEPEC 2004, respectively.

Caryocar Brasiliense

Commonly found in Mato-grossense Cerrado, the pequi tree (Caryocar brasiliense Camb) produces a fruit called pequi, which is sold and consumed by the population where it is produced, in cream, candies, ice creams or in natura, as a typical regional side dish. It is a highly nutritious fruit and hence necessary to the population. The aim of this study was to proceed with the biometric and physical-chemical analysis of pequis collected in the north of the state of Mato Grosso, to contribute with a database to help identify good genoptypes for commercial and industry usage, to build a germplasm bank. Whole fruits from seven different matrixes of Caryocar brasiliense Camb were randomly collected in União do Sul-MT, seasons 2017 and 2019. The mass, transverse diameter, longitudinal diameter, volume and sphericity of fruits and pyrenes have been determined, as well as the number of pyrenes per fruit and pulp mass. The pulp was analyzed for its moisture, pH, total titratable acidity and soluble solids contents. The physical evaluation for fruits and pyrenes show that the observed matrixes had statistically significant differences in all parameters tested, especially on mass, volume and pulp mass. The pequis from matrix 7 have the best results for whole fruit and pyrenes mass, and also for pulp mass and pulp mass/whole fuit ratio. The results for moisture and physical-chemical analysis show that the observed matrixes presented statistically significant differences. The findings are similar to the ones detected in studies with pequis in other regions. Based on the results obtained, the fruits that have been analyzed may be regarded as of interest for business and industry, therefore may be considered to build a germplasm bank.

Aims: Fig plants produce fruits in branches of the year, which grow after emission of buds from the leaf armpits. And the lopping system is one of the most common practices among the green fig farmers to increase production. Thus, the present work aimed to improve the physical, chemical and productive characteristics of fig trees in the semiarid region of Brazil. Study Design: A complete randomized block design was used in a 3x2 factorial scheme (three pruning intensities: 5, 10 and 15 cm in length; and two lopping systems: with and without lopping), constituting six treatments with four replicates. Each experimental plot consisted of five plants, but only the three central plants were used. Place and Duration of Study: The experiment was conducted in the didactic orchard of the Federal Rural University of Semiarid (UFERSA), Mossoró, RN. Methodology: The treatments were: 5 cm pruning without lopping; 5 cm pruning with lopping; 10 cm pruning without lopping; 10 cm pruning with lopping; 15 cm pruning without lopping; 15 cm pruning with lopping. The following variables were analyzed: fruit weight (g), fruit length (cm), fruit diameter (cm), pulp firmness (N), soluble solids content (ºBrix), titratable acidity (%), vitamin C content (mg ascorbic acid 100 g-1 pulp), fruit yield (number of fruits plant-1 and kg plant-1). Data were submitted to analysis of variance by the F test at 5% probability and means were grouped using the Tukey test at 5% probability. The analysis was performed using R software version 3.5.2. Conclusion: Pruning intensity 10 cm in length and the use of lopping system influenced the physical, chemical and productive characteristics of fig plants in the Brazilian semiarid region.

Genotypes of sapote mamey, Pouteria sapota [(Jacquin) H.E. Moore & Stearn] from central-western Michoacán in Mexico were characterized based on physical and chemical fruit characteristics. Cluster analysis of data indicated seven distinct genotype clusters. The greatest variability among clusters was attributed to physical and chemical fruit characteristics. Those were fruit weight, length, width, shape and texture; the ratio of fruit weight to seed weight; seed weight and length; mesocarp thickness and weight; epicarp weight; and the compositional components titratable acidity (TA), protein, total soluble solids (TSS), TSS to TA ratio and TSS to pH ratio. Canonical discriminant analysis was a used to identify the most desirable sapote mamey fruits based on physical (fruit and mesocarp weight) and compositional parameters. Two canonical discriminant functions explained >90% of the accumulated variation a mong the seven clusters of genotypes. Fruit weight, mesocarp thickness, and the ratio of total soluble solids to titratable acidity were dominant in the first function; and fruit weight and mesocarp thickness were dominant in the second. These morphological variables could be used for selecting sapote mamey trees with uniform fruit quality for either direct consumption or processing.

The present study was conducted on five jujube (Ziziphus mauritiana Lamk.) cultivars (Anokhi, Karela, Dill bahar, Ajooba and Dehli white) grown in two locations in Punjab, Pakistan during seasons 2014-2015 and 2015-2016. The aim of the study was to determine genetic diversity based on fruit properties fruit (weight, length, diameter), seed (weight, length, diameter), pulp weight, juice pH, total soluble solids (TSS), titratable acidity (TA), vitamin C, sugars (total, reducing, and non-reducing), antioxidant capacity and total phenolics. All cultivars significantly differed from each other in their fruit physico-chemical attributes. Dehli white cultivar had the highest fruit weight (22.90 g), fruit diameter (37.58 mm), pulp weight (16.83 g) and seed diameter (10.33 mm) than other cultivars. Dill bahar had the highest fruit length (43.75 mm), seed weight (2.69 g), juice pH (4.98), vitamin C content (55.86 mg/100 mL juice) and total phenolic contents (146.98 ?g GAE per mL). Anokhi had the highest seed length (26.13 mm), non-reducing sugars (37.81%), total sugars (47.23%) and antioxidant capacity (1016.8 mM trolox per 100 mL). In Bahawalpur and Faisalabad?s environmental conditions Dehli white and Dill bahar cultivars were with better physical properties. However, according to biochemical properties Ajooba and Anokhi cultivars were better in Bahawalpur.

Several population samples of Rubus idaeus subspp. strigosus Michx. (raspberries) were collected in British Columbia and northern Alberta and a number of characters were studied and compared with the cultivar Trent. Significant differences between populations were found for cane length, number of buds per cane, percentage of buds growing, number of inflorescences and flowers per bud, fruit and seed weight. There was a positive correlation between the total seed weight and the number of seeds, and between the total seed and fruit weight. No distinct types could be established based on location or elevation. None of the populations showed significantly better winter hardiness than the cultivar Trent, and although some had a specific character that was superior, none was found to have overall superiority.

Five strawberry (Fragaria × ananassa Duch.) cultivars were grown in Queensland, Australia to determine whether higher temperatures affect production. Transplants were planted on 29 April and data collected on growth, marketable yield, fruit weight and the incidence of small fruit less than 12 g until 28 October. Additional data were collected on fruit soluble solids content (SSC) and titratable acidity (TA) from 16 September to 28 October. Minimum temperatures were 2 °C to 4 °C higher than the long-term averages from 1965 to 1990. Changes in marketable yield followed a dose-logistic pattern (p < 0.001, R2s = 0.99). There was a strong negative relationship between fruit weight (marketable) and the average daily mean temperature in the four or seven weeks before harvest from 29 July to 28 October (p < 0.001, R2s = 0.90). There were no significant relationships between SSC and TA, and temperatures in the eight days before harvest from 16 September to 28 October (p > 0.05). The plants continued to produce a marketable crop towards the end of the season, but the fruit were small and more expensive to harvest. Higher temperatures in the future are likely to affect the economics of strawberry production in subtropical locations.

High Density Linkage Map

AbstractFruit quality traits play a significant role in consumer preferences and consumption in blueberry (Vaccinium corymbosum L). The objectives of this study were to construct a high-density linkage map and to identify the underlying genetic basis of fruit quality traits in blueberry. A total of 287 F1 individuals derived from a cross between two southern highbush blueberry cultivars, ‘Reveille’ and ‘Arlen’, were phenotyped over three years (2016–2018) for fruit quality-related traits, including titratable acidity, pH, total soluble solids, and fruit weight. A high-density linkage map was constructed using 17k single nucleotide polymorphisms markers. The linkage map spanned a total of 1397 cM with an average inter-loci distance of 0.08 cM. The quantitative trait loci interval mapping based on the hidden Markov model identified 18 loci for fruit quality traits, including seven loci for fruit weight, three loci for titratable acidity, five loci for pH, and three loci for total soluble solids. Ten of these loci were detected in more than one year. These loci explained phenotypic variance ranging from 7 to 28% for titratable acidity and total soluble solid, and 8–13% for pH. However, the loci identified for fruit weight did not explain more than 10% of the phenotypic variance. We also reported the association between fruit quality traits and metabolites detected by Proton nuclear magnetic resonance analysis directly responsible for these fruit quality traits. Organic acids, citric acid, and quinic acid were significantly (P < 0.05) and positively correlated with titratable acidity. Sugar molecules showed a strong and positive correlation with total soluble solids. Overall, the study dissected the genetic basis of fruit quality traits and established an association between these fruit quality traits and metabolites.

Abstract The objective of this study was to determine the most efficient sample size required to estimate the mean of postharvest quality traits of ‘Palmer’ mangoes harvested in two growing seasons. A total of 50 mangoes were harvested at maturity stage 2, in winter (June 2020) and spring (October 2020), and evaluated for weight, length, ventral and transverse diameter, skin and pulp L*, C* and hº, dry matter, firmness, soluble solids (SS), titratable acidity (TA) and the SS/TA ratio. According to the results, the coefficient of variation (CV) of fruit quality traits ranged from 2.1% to 18.1%. The highest CV in both harvests was observed for the SS/TA ratio, while the lowest was reported for pulp hº. In order to estimate the mean of physicochemical traits of ‘Palmer’ mangoes, 12 fruits are needed in the winter and 14 in the spring, considering an estimation error of 10% and a confidence interval of 95%. TA and the SS/TA ratio required the highest sample size, while L* and hº required the lowest sample size. In conclusion, the variability was different among physicochemical traits and seasons, implying that different sample sizes are required to estimate the mean of different quality traits in different growing seasons.

Yield And Quality

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.
