ABSTRACT ‘BRS Vitoria’ is the most important Brazilian table grape cultivar in the domestic and foreign markets, standing out for the seedleness, pleasant flavor, high yield and mildew resistance. The aim of the present study was to determine the effect of the rootstock on the yield, production components, vigor, and physical and chemical characteristics of the ‘BRS Vitória’ grape under irrigation in the Brazilian semi-arid region. The experiment was conducted over eight consecutive production cycles in the period from 2015 to 2018 in a commercial area in the Senador Nilo Coelho project, Petrolina, PE. The treatments were represented by seven rootstocks: ‘IAC 572’, ‘IAC 766’, ‘IAC 313’, ‘Harmony’, ‘SO4’, ‘Paulsen 1103’, and ‘Freedom’, using a randomized block experimental design with four replications. The results were variable among production cycles, with significant effects of the rootstock in some cycles and/or in the overall mean of the cycles. The variables of pruning weight, sprouting, bud fertility, and titratable acidity were not affected by the rootstock in any of the production cycles evaluated in this study. ‘Harmony’ rootstock promoted greater berry mass and diameter but reduced the soluble solids content. Vines of ‘BRS Vitória’ showed moderate vigor, high bud fertility and yield, satisfactory characteristics of bunch and berry, sugars and acids content that meet the requirements of the most demanding markets in all the rootstocks evaluated in this study.

Abstract The study was conducted to determine the effects of Myrobalan rootstock and Blackthorn interstock on fruit physical and chemical traits of five apricot cultivars. The results showed that cultivars grafted on Myrobalan rootstock appear to induce a higher fruit mass when compared with the Blackthorn interstock. Blackthorn interstock showed a tendency to induce a higher soluble solids/titratable acidity ratio than Myrobalan. Values of soluble solids content, total sugars, titratable acidity and fruit firmness between Myrobalan rootstock and Blackthorn interstock were not significant. Regarding cultivars, the greatest fruit mass observed in Roxana in both treatments, and the lowest in Biljana on Myrobalan and in Vera on Blackthorn. The lowest soluble solids, total sugars and soluble solids/titratable acidity ratio were found in Roxana in both variants of grafting, whereas the greatest titratable acidity also observed in Roxana in both cases, respectively. Based on the results from this study, the fruits of Roxana can be recommended for fresh consumption, whereas fruits of the other cultivars can be recommended for processing.

This study aimed to evaluate the influence of different levels of irrigation on the quality parameters involved in the dried-bananas production from 3 different cultivars. The experimental design was a completely randomized factorial 3 x 3, with three genotypes of bananas (Prata-Anã, FHIA-18 and BRS Platina) produced in the semi-arid region of Minas Gerais.) and three irrigation levels (50, 75 and 100% of crop evapotranspiration - ETC), with three replications. For the processing purpose, the fruits were selected at the maturity stage 6. Then they sanitized in hypochlorite of sodium solution at 100 mg L-1, peeled and dehydrated through the drying convective method with hot air, in dryer with forced air, in dryer with forced air circulation at 65ºC for 24 hours. The dried bananas were evaluated according to the following physical and chemical aspects: moisture, length, diameter, firmness, color (brightness, chroma and ºHue), soluble solids and titratable acidity, and sensory characteristics: purchase intention and acceptance. The humidity, length, diameter, firmness, color and acidity of dried bananas were influenced by the different studied irrigation levels. In the sensory evaluation, the best result regarding appearance, color, texture and flavor requirements was observed in banana processed from 'Prata-Anã' irrigated with the total level of water (100%). The dried banana processed from 'BRS Platina' was the least accepted in the sensory tests.

<p>The proposal of the present research includes eight Blueberry jam formulations, from Rabbiteye species (Climax and Powder Blue varieties). For gelling, four formularizations were used: synthetic ATM pectin (F1), pectin obtained from passion fruit skin extraction (F2), synthetic BTM pectin (F3), and synthetic BTM pectin mixed with gums mixture (F4). Product Sensorial tests were performed and sensorial attributes evaluated were flavor, color, texture and appearance. According with sensorial tests and the Anova results, it could be concluded that the two more accepted formularizations were: F2 and F4 (For Climax variety) and F1 e F4 (for Powder Blue variety). Therefore, these formulations were evaluated for pH, total soluble solids, titratable acidity, water activity, total and reducing sugars, total and anthocyanins, from the first day of storage and after 30, 90 and 120 days to analyze the storage effect on jam characteristics. Jam processing reduces anthocyanins content (about 57% for conventional formulations and 35% for light jam); however, the jam may still be considered anthocyanins source, owing to the high content even after processing. After 40 storage days a significant decrease on jam anthocyanin levels was observed, except the products with higher sugar contents. Comparing the anthocyanin levels at time zero and after 120 days of storage, it appears that the decrease in pigment concentration was higher in the climax of fruit variety (approximately 44%). After 30 days of storage, the percentage of acidity, pH, water activity, moisture and soluble solids content remained constant.</p><p>&nbsp;</p><p>DOI: 10.14685/rebrapa.v5i1.150</p>

The effects of early preharvest application of 18 ethephone ((2-chloroethyl) phosphonic acid) treatments on the size, weight, soluble solids content, pH, titratable acidity, soluble solids/acid ratio, and the keeping quality of lowbush blueberry fruit (Vaccinium angustifolium Ait.) were studied. For all these characteristics, no significant differences were observed between fruits receiving the ethephon treatments and the untreated fruits except in the case of fruits receiving 1,000 ppm ethephon when about half-grown. Weight of berries per unit volume from this treatment was significantly higher than for all other treatments including untreated fruits. These findings indicate that early preharvest application of ethephon for selective abortion of barrenberry fruits in lowbush blueberry fields does not adversely affect the observed characteristics of blueberry fruits.

ABSTRACT In recent years, with the change in consumer profile, the demand for foods with low levels or even without pesticides has increased. Bagging fruits in the field is considered one of the oldest and effective phytosanitary practices, being an alternative to chemical control. The aim of the present work was to test some types of packaging in the bagging of pitaia fruits during their development in the plant in order to maintain quality. Red pitaia plant fruits [Hylocereus undatus (Haw.) Britton & Rose] five years post-planting were used. The experimental design used was random blocks, with 5 treatments, 4 repetitions and 10 fruits per plot. Treatments consisted of control (without bagging), newspaper bag, Kraft paper bag, waxed paper bag and Non-woven bag (NW). The following characteristics were evaluated: percentage of remaining fruits up to harvest; percentage of damaged fruits; fruit mass; longitudinal and transverse diameter; pulp yield; peel thickness; soluble solids content (SS); pH; titratable acidity (TA) and SS/TA ratio. There was no difference among treatments for most of the characteristics analyzed, except for percentage of remaining fruits on the plant and percentage of damaged fruits. Bagging does not alter the physical and chemical characteristics of red pitaia fruits. NW and newspaper bags are more effective in bagging pitaia fruits due to greater permanence in the fruit during its development in the plant.

Resumo A significant portion of papaya production in the state of Minas Gerais originates from irrigated crops, and irrigation management using the partial root zone drying technique (PRD) is a fundamental alternative to reduce water waste. This study aimed to evaluate the quality of ‘Tainung 1’ papaya produced under PRD in semi-arid conditions of northern state of Minas Gerais. PRD treatments were composed of reduction of the calculated irrigation water (CIW) by 50%, applied on one side of the irrigation line, with alternation of 7, 14 and 21 days or without alternation and full irrigation, applying 100 % CIW in both lateral plant rows. Each experimental plot consisted of ten plants, and from six plants, fruits were harvested for evaluations at harvest point and when ripe. At harvest point, fruits had peel color, titratable acidity, ratio, pulp size and thickness similar to those produced without water deficit. Firmness, soluble solids content, fresh mass and central cavity diameter are distinct as a function of PRD condition. When ripe, only firmness varied according to PRD treatments. The quality of ‘Tainung 1’ papaya produced by partial root zone drying in semi-arid conditions was not compromised.

Niagara Rosada

The objective of this study is to evaluate the effect of rootstocks on grape production, quality and antioxidant capacity of ‘Niagara Rosada’ grape in two productive cycles. The work was developed in Jundiaí-SP, Brazil (26° 06’ S, 46° 55’ W and an average altitude of 745 m). The experimental design was in randomized blocks with subdivided plots, the plots being represented by the rootstocks and the subplots by the production cycles, with four replications, each consisting of 6 plants. The treatments consisted of a combination of ‘IAC 313 Tropical’, ‘IAC 572 Jales’, ‘IAC 571-6 Jundiaí’, ‘IAC 766 Campinas’ and ‘106-8 Mgt’ as rootstocks and ‘Niagara Rosada’ as graft, and the production cycles were 2013 and 2014. The number of bunches, production and productivity of the vines, the physical characteristics of bunches, berries and stalks and the physicochemical composition of the must (soluble solids content, titratable acidity, pH and the relation soluble solids/titratable acidity) were evaluated in production cycles of 2013 and 2014). The content of chlorophylls, anthocyanins, carotenoids, flavonoids and total phenolic compounds and the antioxidant activity of grapes were also evaluated in grape berries. The rootstocks did not influence the production and physical quality of ‘Niagara Rosada’ grapes. As for the chemical characteristics, rootstocks only had an effect on solids content, and ‘IAC 766’ and ‘106-8 Mgt’ rootstocks promoted higher values of this characteristic. Likewise, the total phenolic compounds and the antioxidant activity of the grapes were not influenced by the studied rootstocks. The vines in 2013 presented higher production and better physical characteristics of the grapes, however, the soluble solids content in this cycle was lower than in 2014.

ABSTRACT The objective of this work was to perform foam-mat drying of yellow mombin pulp, verifying the kinetics and mathematical modeling of the process, and characterizing the obtained product with respect to physical and chemical characteristics, compared with the fresh pulp. Foam-mat drying was carried out with the aid of the foam agent Emustab®, at temperatures of 50, 60, 70 and 80 °C. The drying data were analyzed and fitted to four mathematical models (Wang & Singh, Verma, Page and Midilli). Effective diffusion coefficient and activation energy were determined. Titratable acidity, pH, soluble solids content and vitamin C content, as well as the solubility in water of yellow mombin powder and color variance (L*, a*, b*) were analyzed in both fresh and dehydrated pulp. The Wang & Singh model showed best fit at the temperature of 50 °C, whereas the Midilli model showed the best mathematical fit at temperatures of 60, 70 and 80 °C. Net diffusion coefficient and activation energy values were proportional to the drying temperature. Drying of the foam at 60 °C indicated guarantee of quality of yellow mombin pulp with respect to titratable acidity, pH and color of the a* coordinate.

This study evaluates the post-harvest quality of fruits of different banana cultivars regarding type of propagation when stored in cold at three different times at constant temperature. The experiment was carried out at the Fazenda Terra Santa in the semi-arid region of northeastern Brazil. We applied a completely randomized experiment in a 6 &times; 3 factorial, evaluating the post-harvest development of &lsquo;Prata-an&atilde;&rsquo; and &lsquo;Pacovan&rsquo; cultivars, propagated in three different ways and analyzed at three distinct times of storage in the cold. The following fruit quality variables were analyzed: soluble solids, vitamin C content, titratable acidity, and potential of hydrogen (pH). The analysis of variance revealed a significant effect at 1% probability in all sources of variation of analyzed variables of Soluble Solids and pH, for the unfolding treatments &times; storage time of the analyzed variables Vitamin C and titratable acidity, and for the source of variation treatment of the vitamin C variable. The &lsquo;Prata-an&atilde;&rsquo; cultivar propagated by rhizome with &ldquo;ceva&rdquo; was the most efficient technique of propagation, providing good soluble solids and titratable acidity contents, but with the lowest pH values.

The effect of revalorized Bimi leaves (B) and/or mustard (M) addition, as supplementary ingredients, to develop an innovative kale (K) pesto sauce was studied. Microbial, physicochemical (color, total soluble solids content -SSC-, pH and titratable acidity –TA-) and sensory quality were studied during 20 days at 5 °C. Bioactive compounds changes (total phenolics, total antioxidant capacity and glucoraphanin contents) were also monitored throughout storage. The high TA and pH changes in the last 6 days of storage were avoided in the K+B pesto when adding mustard, due to the antimicrobial properties of this brassica seed. SSC was increased when B + M were added to the K pesto, which positively masked the kale-typical bitterness. Mustard addition hardly change yellowness of the K pesto, being not detected in the sensory analyses, showing K+B+M pesto the lowest color differences after 20 days of shelf life. The addition of Bimi leaves to the K pesto enhanced its phenolic content while mustard addition did not negatively affect such total antioxidant compounds content. Finally, mustard addition effectively aimed to glucoraphanin conversion to its bioactive products. Conclusively, an innovative kale pesto supplemented with Bimi by-products was hereby developed, being its overall quality well preserved up to 20 days at 5 °C due to the mustard addition.
