Industrial Processing Affects Product Yield and Quality of Diced Tomato

The tomato industry has been searching for new genotypes with improved fruit production, both in the field and industrially processed, together with high-quality performance under sustainable management conditions. This research was carried out in Southern Italy with the aim of assessing the effects of industrial processing on the yield and quality of four tomato hybrids grown according to organic farming methods and addressed at dicing. MAX 14111 and HMX 4228 showed the highest values of field and processing yield as well as reduced sugars and fructose. MAX 14111 had the highest values of total solids and soluble solids, titratable acidity, fiber, energetic value, polyphenols, and also rutin, though not significantly different from Impact. HMX 4228 performed best in terms of sugar ratio, color and naringenin. Concerning the diced products, the sensorial qualities of the four hybrids differed significantly. Total polyphenols, naringenin and rutin in the tomato fruits were higher in the processed than in the raw product. The appreciable fruit yield and quality resulting from both field and processing phase represent a promising perspective for identifying improved tomato genotypes addressed at dicing.

ABSTRACT The objective of this study was to evaluate the effect of pruning intensity on yield and quality of blueberries fruits. It was evaluated the cultivar Misty. The treatments were: absence of pruning; light pruning; regular pruning and drastic pruning. The experimental design was randomized blocks with four replications. The variables analyzed were fruit production, fruit size, pH, total soluble solids (TSS) and total titratable acidity (TTA), and the bioactive compounds such as phenolic compounds, anthocyanins and antioxidant activity. The plants that received drastic pruning showed higher averages of production and fruit size. The highest concentrations of phytochemical compounds in blueberry fruits occurred as pruning was more drastic. The use of different intensity of pruning can modify the productive behavior and postharvest quality of fruits.

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.

The objective of this study was to evaluate the productivity and quality of melon fruits as a function of the dose and time of application of biostimulant in the conditions of the semi-arid region of Paraíba. The experiment was carried out at the Federal University of Campina Grande, campus of Pombal - PB, Brazil, in a randomized block design in a 4 x 5 split plot scheme, with doses of biostimulant (0; 0.5; 1.0; 1, 5 and 2.0 L ha-1) and in the subset of the biostimulant application times (15; 20; 25 and 30 days before harvest - DAC), in four replications. Characteristics related to fruit production and quality were evaluated. There was no interaction between the factors of dose and application time of the biostimulant in any of the evaluated characteristics. Thus, the highest estimated values of number of fruits per plant, fruit mass and total melon production were obtained with the application of doses ranging from 0.9 to 1.5 L ha-1 and at the time of application it varied from 22,5 to 23.6 DAC. The content of soluble solids increased 5.5% when the biostimulant dose of 2.0 L ha-1 was used and 4.4% when the product was applied 15 days before harvest.

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.

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.

ABSTRACT The aim of the present study was to evaluate the effect of stem repair grafting on the recovery of damaged plants, yield and quality of yellow passion fruits in organic system. The experiment was conducted simulating five stem damages (treatments) in randomized complete block design with four replications of four plants each. After reaching on average 7.3 ± 1.2 mm in stem diameter, plants were perforated at 20, 40, 60 and 80% of the stem diameter with the aid of a steel drill. The reduction in plant stand treatment with 80 % damage reduces plant productivity. Then, bridge-type grafting was performed by connecting the top and bottom of the injury. The grafting success percentage ranged from 81.3 to 95.8% and did not differ between treatments, but the survival rate of plants was lower in treatments with 40 and 80% of injuries. There were no statistically significant differences between treatments for the following variables: number of fruits per plant, average fruit weight, total soluble solids (TSS), total titratable acidity (TTA) and (TSS/TTA) ratio. Recovery stem grafting allows injured plants to maintain the same productivity by up to 60% compared to plants without injuries.

ABSTRACT Pruning guava trees at different times is an important management tool that allows year-long staggering of fruit production. In this context, this study aimed to evaluate the phenological characteristics, yield and fruit quality of the 'Paluma' guava tree at different pruning times in Botucatu, SP. The study used a completely randomized design with four treatments, four replicates and a useful experimental plot plant. The treatments consisted of four different pruning times, August 27, September 11, September 26 and October 11. The following phenological phases were evaluated: branch establishment, flowering, early fruiting, fruit ripening and harvesting. It was determined the number of flower buds, fixed fruits and fixation index fruit were determined. The fruit growth curve was obtained by measuring the transverse and longitudinal diameter. At the time of harvest, the number of fruits per plant, yield and productivity were measured. In the harvested fruits, the fresh mass, the transverse and longitudinal diameter, the flesh and core thickness, the flesh and core mass, soluble solids, titratable acidity and pH were determined. The 'Paluma' guava trees pruned in August showed higher phenological stage durations than the other pruning times; however, those pruned in early September showed higher fixation index fruit, fruit yield and better physical characteristics. The guava trees pruned in August showed lower titratable acidity values and higher soluble solids/titratable acidity ratio.

ABSTRACT The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this study was to evaluate the effect of different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity and quality. Quantitative and qualitative fruit production parameters of plants visited by Apis mellifera L., manually self- and cross-pollinated plants and plants without pollination were analyzed and compared. Fruit production was high for all treatments and all fruits presented four seeds per fruit, on average, confirming that this grape cultivar is autogamous. However, fruit set after spontaneous self-pollination was statistically lower than that of all other treatments, and pollination by A. mellifera showed the highest fruit production. Furthermore, pollination by honey bees resulted in increased biomass, reflected on fruit weight, but the content of soluble solids remained unchanged. The results of this study showed that there is no need of pollinators for fruit production of ‘Bordô’ cv., but the presence of these agents, in particular Apis mellifera, influences commercially important quality parameters such as fruit yield and fresh weight. Therefore, the use of bee hives in areas with deficit of pollinating insects may promote an improvement in yield and quality of this cultivar.

ABSTRACT Squashes and pumpkins are known and grown worldwide, including the Tetsukabuto type, a hybrid of Japanese origin. On this work, we evaluated yield and quality of parthenocarpic fruits of hybrid Tetsukabuto developed with the use of 2,4-D doses, in the climatic conditions of the Brazilian semiarid, in the city of Pombal, state of Paraíba, Brazil. The experiment was carried out from February to May 2013, in complete blocks at random and five replications. Treatments corresponded to five 2,4-D doses (0, 90, 180, 270, and 360 mg/L) applied to female flowers, and a control treatment, where fruits developed out of insect pollinated flowers. We evaluated number of flowers per plant, duration of flowering, number of fruits per plant (used to estimate number of fruits per hectare), fruit set index, fruit mass and transversal and longitudinal diameters, pulp thickness and content of soluble solids, total fruit production and yield. Number of fruits per plant and fruit mass increased 269.5 and 15.4%, respectively, with 212.1 mg/L and 360.0 mg/L of 2,4-D, when compared to the control treatment. Increasing the 2,4-D dose from 0.0 to 241.4 mg/L resulted in 38.2% rise in plant production. Correlations were significant only for number of flowers x number of fruits per plant (NF) and NF x yield, with coefficients of 87.5 and 82.7%, respectively. These results indicate that fruit induction using 2,4-D resulted in higher fruit set, independent of the 2,4-D dose applied.
