Fruit Quality of Some Hot Peppers Cultivars from Vegetable Research Development Station Buzau

The aim of this study was to assess phenotypic diversity in terms of fruit quality traits and yield, and also to establish valuable genotypes for breeding purpose suitable for different direction of use. Ten cultivars of hot peppers bred at VRDS Buzau were collected and fruit quality (dry matter content, fruit firmness, the total soluble solids, titratable acidity and ascorbic acid content) was evaluated at different ripening stages. A very highly significant difference (p<0.01) was found for the studied quantitative parameters, showing a great variability among the studied accessions. During ripening, the dry matter content, the firmness, the TSS content and the titratable acidity increase for all studied cultivars and there were significant differences between them. A broad range of variation was noted in Vitamin C content in both stages of maturity. In the present research work, a great variability among the studied accessions was found. Fully ripe fruits were found considerably richer in the bioactive factor than unripe fruits. Our results have selected two important genotypes: A12A, an accession suitable for obtaining chili powder, due to the his low content in dry matter and total soluble solids and accession A135 suited for fresh consumption and for long shelf life because it has a high firmness.

Quality Aspects

Abstract Pepino dulce (Solanum muricatum Aiton) or Pepino has been growing to produce edible, juicy and attractive fruits. The imported fruits and national small scale of Pepino dulce production are currently stored and commercialized under the absence of postharvest handling recommendations. Therefore, this work aimed to evaluate the quality aspects of Pepino dulce fruits in distinct ripening stages, forms of packaging and conditions of storage. The trial was conducted in a 2x2x2 factorial scheme - 2 ripening stages (ripe and immature) x 2 forms of packaging (with and without wrapping in plastic film) x 2 conditions of storage (room: 25 °C ± 2 ºC and 57% ± 5% of relative humidity (RH); cold: under refrigeration 10 °C ± 2 °C and 85% ± 5% of RH) – in a complete randomized block design. Fruit quality attributes, such as vitamin C, chemical and phenolic content, fruit color (mesocarp), firmness, dry matter content, total titratable acidity (TA), total soluble solids and pH, were evaluated. Fruits showed a centesimal composition with low calories and a significant content of potassium (K), phosphorus (P) and magnesium (Mg), which can contribute to the daily supply of these elements. For commercialization purposes, the association of packaging (plastic wrapping film) and refrigerated storage (cold: 10 °C ± 2 °C and 85% ± 5% of RH) to maintain the characteristics of fruit quality after a 15 days period is more important than its individual use.

The geographic location of Bucharest area, the nature of its soil and its climate offer remarkably favourable conditions for nectarine growing, with juicy and well flavoured fruit, good for fresh consumption and processing. The five years' investigation (1996-2000) has helped to identify some nectarine cultivars and hybrids (NJN 58, ARK 165, ARK 139, Morton, ARK 107, Romamer I, ARK 125, Firebrite) with exceptional fruit quality (dry matter content, titratable acidity, vitamin C content, overall sugar, and amount of pectic substances). Dry matter content varied over the three years from 8.3 to 18.5% (NJN 68), meanwhile titratable acidity varied between 0.26 and 1.08% (Romamer I). Sugar / acidity ratio was within the limits of 8.6 and 36.5 (Nectared 7). Nectarines have high vitamin C content, over 10 mg/100g (Fairlane, NJN 67, Regina, Harko), glucides were found in Firebrite, Romamer I varieties and NJN 21, CIR1T127, HFSR3P4, HNA hybrids. Some cultivars have been recommended for planting in this southern area of Romania (Crimsongold, ARK 125, Harko, Hardyred, ARK 134), others used as quality genitors (ARK 85, Nectared 7, NJN 21, ARK 21, ARK 134, Fantasia) in breeding projects.

Tomato Yield

The performance and suitability of different substrates for the soilless culture of tomato plants (<I>Lycopersicum esculentum</I> Mill., cv. Belladona) were studied over a 5-month period in a closed soilless culture system employing five different substrates (perlite, pumice or maize and their mixtures with 50% shredded maize stems in an unheated glasshouse). Plants grown in a maize stem-containing medium produced earlier fruits, followed by pumice. Plants grown in pumice and perlite substrates obtained lower total yield; a higher yield was associated with the addition of maize shredded stems. Pumice + 50% maize and 100% maize produced higher total number of fruits per plant. Fruit quality parameters such as mean fruit weight, fruit firmness, total soluble solids, titratable acidity, ascorbic acid and carotenoids were influenced by the treatment, while EC, pH and dry matter content were not. The results suggest that the addition of maize in perlite and pumice could improve inorganic substrates properties for tomato soilless culture, leading to higher yields and better fruit quality.

On-tree maturation was monitored in a commercial ‘Royal Gala’ apple orchard in two separate years (2016 and 2017) and was found to advance more quickly in 2017 as compared with 2016. Dry matter was predicted using a handheld infrared spectrometer and dry matter content (relative to fresh weight) was 18.2 % in 2016 and 14.7 % in 2017. The lower average dry matter content in 2017 was hypothesized to be associated with accelerated maturation on the tree. Apples were harvested for storage testing, in both years, at a target maturity at which internal ethylene levels had reached approximately 1 µL L-1, starch clearing index was between 2-4 on the Cornell starch chart and IAD value (measure of relative chlorophyll content in the peel) was approximately 0.5. Consequent, instrumentally measured flesh quality changes were monitored after ultra-low oxygen CA storage (0.7 kPa O2 + 1.0 kPa CO2) at 0.5 °C for 3 and 6 months. The firmness, soluble solids and titratable acidity were much higher in the apples from the 2016 harvest. While these quality measures declined during 3 and 6 months of storage, they were consistently higher in the apples from the 2016 season. These results show that when dry matter contents were higher for ‘Royal Gala’ apples from this orchard, harvest maturity was delayed and fruit were much firmer and had higher contents of soluble solids and somewhat higher titratable acidity at harvest and after ultra-low oxygen CA storage for up to 6 months.

The effects of harvest date (5 dates, between 100 and 140 days after full bloom) and carbon supply (2 leaf-to-fruit ratios, 10 and 100) on mango fruit (cv. Cogshall) quality and maturity were studied to find reliable indicators that take fruit physiological maturity into account and to establish a compromised harvest date according to the market. Fruit size and density varied with regard to the harvest date and assimilate supply. Changes in total soluble solids and titratable acidity were well correlated with concentrations of major soluble sugars and organic acids. Potassium concentration was increased according to harvest date. Metabolic changes occurred at 126–133 and 133–140 days after full bloom in fruit subjected to non-limited and stress conditions of assimilate supply, respectively. During this stage, sucrose and malic acid concentrations strongly increased, whereas those of starch and citric acid decreased according to the leaf-to-fruit ratio treatment. Synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) and malonyl ACC, and a rapid increase in the respiration rate were observed during this period. The shortage of assimilate supply delayed the onset of maturation and reduced its intensity. Storage quality of mango cv. Cogshall may be influenced by assimilate supply since the K+ to Ca2+ ratio and the pulp dry matter content, in particular, were enhanced in fruit from the 100 leaf-to-fruit ratio treatment. Results for mango cv. Cogshall suggested that total soluble solids, sucrose, and malic/citric acid ratio can be used as physiological indices for mango fruit, whereas fruit fresh mass, density, and pulp dry matter content can be useful indicators for when to harvest fruit. It appeared that 133 days after full bloom was an optimal harvest date for fruit grown under non-limited conditions of assimilate supply, for a market where the time between harvest and consumption of fruit is short.

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.
