In this investigation the effects of cultivar, row spacing and different stages of maturity on qualitative characteristics of tomato (ascorbic acid, total soluble solids (TSS), β-carotene and lycopene) have been evaluated. Experiment was performed by factorial analysis with 3 replicates in completely randomized design (CRD). First treatment was three cultivars of tomato, second treatment was four planting distances and third treatment was different stages of maturity. The results showed that all treatments had significant influence on the levels of ascorbic acid, soluble solids, β-carotene and lycopene. Generally, wider spacing and deep red fruits had the highest quality. Therefore, choosing appropriate cultivars, special planting distances and suitable stage of maturity can increase fruit quality of tomato.

The objective of this work was to evaluate the visual and chemical quality of tangerines after mechanical damage by impacts. The tangerine cultivars Montenegrina and Rainha were submitted to different degrees of impact and evaluated for decay and oleocellosis, loss of fresh weight, total soluble solids, total titratable acidity and ascorbic acid degradation, as well as for epicarp color changes. Experiments with three replicates and experimental units of six fruit for each cultivar were done in a completely randomized design. Impact produced qualitative internal and minor external changes on tangerines. The main modifications produced by impact on the fruit were losses of citric acid and soluble solids, which increased the solid:acid ratio, and losses of ascorbic acid. 'Montenegrina' tangerines are more susceptible to internal quality damage than 'Rainha'.

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

The main objective of the study was to standardize enrichment of aonla pulp to develop fruit bars. The experiment was laid out in Completely Randomized Design (CRD) with 10 treatments. Aonla pulp was blended with 25 to 75% of different fruit (mango, papaya and jackfruit) pulp viz. Aonla pulp, Aonla with mango, papaya and jackfruit in different proportion of 3:1, 1:1 and 1:3 each fruit respectively. The initial moisture content was higher in aonlapulp enriched with mango pulp in 1:3 proportions. Enrichment of aonlapulp with fruit pulp of mango, papaya and jackfruit reduced the ascorbic acid, titratable acidity and tannin content of the resultant fruit bars compared to that from pure aonla pulp, which is an indication in the reduction of astringency. Enrichment also resulted in an increase in total soluble solids, reducing, non-reducing and total sugars of the resultant fruit bars. Enrichment of aonla pulp with fruit pulp of provitamin A rich fruits like mango, papaya and jackfruit showed a rise in total carote-noids and reduced astringency and acidity, thereby resulting in fruit bars with altered palatability and enhanced nutrition. Enriched fruit bars contained three vital antioxidants viz. Vitamin C, carotenoids and polyphenols of all the treatments, enriched fruit bar containing 25 % aonlaand 75 % mango (T4) was found superior in organoleptic evaluation.

This study aimed to verify the effect of the association between refrigeration and packaging on the preservation of postharvest quality of pitombas during storage. The fruits were harvested, transported to the laboratory, where they were selected, washed with neutral detergent and drinking water, and left to dry. Subsequently, the fruits packed in polypropylene (PP), low-density polyethylene (LDPE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) + expanded polystyrene (EPS), and no packaging (Control). After this process, they were stored at temperatures of 6, 8, 10, 12, and 14±1 °C at 75±5% relative humidity (RH). The fruits were evaluated during 12 days for postharvest preservation, firmness, soluble solids content, pH, hue angle and chroma of the peel, with three replications of 10 fruits each, using a completely randomized design in a 5 × 5 × 7 factorial scheme (5 temperatures × 5 packages × 7 days of analysis). The results were subjected to analysis of variance (P≤0.05) and, when significant, the means were compared using the Scott-Knott test and regression at a 5% significance level. The use of LDPE packaging associated with refrigeration at 6 °C can be used to store pitombas for 12 days, as these conditions preserved the evaluated parameters, guaranteeing fruit quality.

Beetroot (Beta vulgaris L.) is a culture of great demand in Brazil due to its high nutritional value. However, water availability is a determining factor on its production. An alternative to reduce the damage caused by water stress is to apply organic solutes, such as ascorbic acid. The purpose hereof was to evaluate the postharvest quality of beetroots grown under different irrigation depths and ascorbic acid doses. The experiment was carried out in the Human, Social, and Agricultural Center&rsquo;s Postharvest Physiology and Technology Laboratory of the Federal University of Para&iacute;ba, Bananeiras, Para&iacute;ba, Brazil, in a completely randomized design with five doses of ascorbic acid (0.00, 0.29, 1.00, 1.71, and 2.00 mM) and five irrigation depths (40.0%, 51.6%, 80.0%, 108.4%, and 120.0% of the evapotranspiration), combined according to each Box Central Compound experimental matrix, totaling nine treatments with five repetitions. The variables total soluble solids, electrical conductivity, hydrogenation potential, titratable acidity, total soluble solids and titratable acidity ratio, moisture, dry matter, and mineral matter were evaluated. The data were submitted for analysis of variance and polynomial regression. There was a significant interaction between the irrigation depths and the ascorbic acid doses in every variable, except for electrical conductivity and mineral matter. The postharvest characteristics of beetroots improved with applications of ascorbic acid doses in the thinner irrigation depths. The greatest dose of ascorbic acid (2 mM) in the thinner irrigation depth (40%) increases the postharvest quality of beet tuberous roots.

The aim of this study was to evaluate the changes in quality of fruits of two species of physalis (P. angulata and P. pubescens) harvested from family farmer orchards in different maturity stages, comparing with fully ripen fruits to those of the commercial species (P. peruviana) of similar maturity. The experiment was conducted in a completely randomized design, in five maturity stages for P. angulata and in four for P. pubescens. Data were submitted to variance analysis and means of the maturity stages compared by the Tukey test at 5 % probability. For the comparison of fully ripen fruits of P. peruviana with the two species produced in different locations were used six replications and the means compared by Dunnett's test at 5 % probability. The fruit diameter varied from 15.1 to 18.0 mm that classifies it as of caliber B. During maturation the color of the fruit evolved from green to totally yellow (P. angulata) and to yellow-brown with purplish features (P. pubescens). The soluble solids (SS) contents of the fruits of P. angulata were superior to those of P. pubescens and the commercial species. Comparing with commercial species, the SS/AT ratio was higher in locally produced fruits, indicating more palatable fruits. Fruits of P. angulata present favorable characteristics for fresh consumption, with potential for extensive cultivation and trade in family horticulture.

This study was carried out to evaluate the influence of a synthetic progesterone ear implant on weight gain and meat quality of Nellore heifers. Twenty-eight Nellore heifers with an average initial weight of 240.9 kg were used in this experiment. All heifers received the same dietary management, in an intensive rearing system, with mineral salt and water ad libitum. Heifers were distributed, in a completely randomized design, into two treatments (with and without progesterone ear implant) with seven replications, in 14 stalls. Analysis of variance was performed, and, for non-parametric variables, the Kruskal-Wallis test was applied. Parameters referring to the meat quantitative and qualitative characteristics, represented by the weight and yield of the carcass, conformation, marbling, color, meat texture, carcass morphometric measurements, longissimus dorsi muscle area, and fat thickness, were not affected by the progesterone hormone. The use of the progesterone ear implant did not change the carcass physical characteristics or the meat quality characteristics.
