Pericarp Browning

Background: Phospholipase D (PLD)is closely related to browning and senescence of postharvest longan fruit. Objective: This study investigated the effects of 2-butanol (a PLD inhibitor) on the expression and regulation of PLD during storage of longan fruit at a low temperature. Methods: Senescence-related quality indices showed that the 2-butanol-treated fruit presented lower pericarp browning index, pulp breakdown index and total soluble solid value than the untreated fruit. Results: The fruit treated by 60 µL/L 2-butanol exhibited the strongest inhibition on senescence, which significantly delayed changes in weight, titratable acidity content, total soluble solid content and ascorbic acid content. This treatment maintained a high level of total phenolic content and caused significant inhibition on pericarp browning and pulp breakdown. Through ELISA method, 60 µL/L 2-butanol treatment also reduced PLD activity. Real-time RT-PCR (RT-qPCR) results showed that PLD mRNA expression level was inhibited by 60 µL/L 2-butanol within 15 days. Western-blotting results further confirmed the differential expression of PLD during storage, and a relatively higher expression for PLD protein was found in control compared to the 2-butanoltreated fruit during 15-d storage. Conclusion: These results provided a scientific basis and reference to further investigating postharvest longan quality maintenance by regulating the PLD gene expression.

The cracking of sweet cherries causes significant crop losses. Sweet cherries (cv. Bing) were coated by electro-spraying with an edible nanoemulsion (NE) of alginate and soybean oil with or without a CaCl2 cross-linker to reduce cracking. Coated sweet cherries were stored at 4 °C for 28 d. The barrier and fruit quality properties and nutritional values of the coated cherries were evaluated and compared with those of uncoated sweet cherries. Sweet cherries coated with NE + CaCl2 increased cracking tolerance by 53% and increased firmness. However, coated sweet cherries exhibited a 10% increase in water loss after 28 d due to decreased resistance to water vapor transfer. Coated sweet cherries showed a higher soluble solid content, titratable acidity, antioxidant capacity, and total soluble phenolic content compared with uncoated sweet cherries. Therefore, the use of the NE + CaCl2 coating on sweet cherries can help reduce cracking and maintain their postharvest quality.

Two trials in different agricultural farms were carried out from October 2014 to June 2015 with the aim to assess the advantages linked to the substitution of the low density polyethylene (LDPE) films for soil mulching with the Mater-Bi<sup>®</sup> biodegradable films in the strawberry cultivation under tunnel in Campania. Lifetime of biodegradable mulch and influence of type of mulch on the yield and the quality of cvs Sabrina and Fortuna were evaluated. Plants were cultivated on mulched, raised beds, high 40 cm from bottom soil. Mater-Bi<sup>®</sup> film was 20 <span>µ</span>m thick while LDPE film was 50 mm thick. The physical-chemical parameters (firmness, pH, total soluble solid content, titratable acidity and skin colour) and some bioactive compounds (total polyphenols, flavonoids, anthocyanins, antioxidant activity) of fruits were determined by three samplings effected in consecutive months (from March to May 2015) of the harvest cycle. Biodegradable film guaranteed an effective mulch along the whole strawberry cycle (9-10 months including the time of drawing up of film). Yields of cv Sabrina on LDPE was 18% higher than those on Mater-Bi<sup>®</sup> while the opposite was detected in cv Fortuna (+10%). The physical-chemical parameters of fruits were not modified by the mulches. The content of the bioactive compounds, instead, resulted, in each time of sampling, significantly higher in fruits picked on Mater-Bi<sup>®</sup> based film.

<p>This study aimed to investigate the effects of grafting tomato on different tobacco rootstocks on quality factors and nicotine content. The commercial variety (Solanum lycopersicum ‘H2274’) (BIOTECH) of the tomato was used as the scion plant, and six different tobacco (Nicotiana tabacum L.) rootstocks were used: Taşova, Tekel, Muş, Samsun, Dişbudak, Hasankeyf cultivars. Cleft grafting method was used in all plants. Yield of non-grafted and grafted plants grown in open-field conditions was calculated, and there was a significant increase in yield in grafted tomatoes compared to non-grafted tomatoes. There was significantly increased lycopene and β-carotene levels (mg kg-1), especially in ‘Tekel’, ‘Taşova’, ‘Samsun’, and ‘Hasankeyf’ tobacco grafts. There was a statistically significant difference between grafted and non-grafted plants according to 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical retention capacities and total phenol (TP) values. Evaluation of quality determinants including pH values, titratable acidity values (citric acid %), soluble solid content (SSC)(oBrix) , fruit size ratios, showed that tomatoes grafted with ‘Muş’ tobacco rootstock were of higher quality. There was no significant difference between grafted and non-grafted plants according to nicotine analysis of the tobacco-grafted tomatoes, and due to acceptable ranges of nicotin level on tobacco grafted tomato plants were considered to be suitable for consumption. It could be concluded that grafting practices have significantly positive effects on tomato yield and quality.<br /><br /></p>

Os tratamentos, com distância de 2,0 m entre linhas, foram distribuídos em blocos ao acaso, com quatro repetições de 12 plantas por parcela, em esquema fatorial 4 × 2, correspondente as distâncias de 3, 6, 9 e 12 m entre plantas nas linhas com e sem poda da haste principal, ao atingir o sistema de sustentação. Os componentes avaliados foram número de frutos colhidos, produção por planta, produtividade e na polpa dos frutos, os valores de sólidos solúveis, acidez titulável, pH e a relação sólidos solúveis/ acidez titulável. A interação entre os fatores estudados exerceu efeitos significativos no número de frutos colhidos, produção por planta, teor de sólidos solúveis e acidez titulável. A produtividade foi influenciada pelos dois fatores de forma isolada. O pH da polpa respondeu apenas ao espaçamento entre plantas nas linhas e a relação SS/AT não foi influenciada por nenhuma das fontes de variação estudadas. O aumento das distâncias de plantio nas linhas promove ganho de produção por planta, mas reduz a produtividade. Plantas podadas na haste principal apresentam maior produtividade. A irrigação com água de qualidade restritiva à agricultura não inibiu a capacidade produtiva do maracujazeiro amarelo acesso Guinezinho e não prejudicou a qualidade química dos frutos.   Palavras-chave: acesso Guinezinho, densidade de plantio, Passiflora edulis Sims.     MORAIS, R.

SPATIAL ARRANGEMENT AND PRUNING IN THE PRODUCTION AND CHEMICAL QUALITY OF YELLOW PASSIONFRUIT IRRIGATED WITH SALINE WATER       2 ABSTRACT   An experiment was carried out in  Coronel Ezequiel municipality, Rio Grande do Norte State, Brazil, to evaluate the effects of planting density and pruning of the main stem on yellow passion fruit plants access Guinezinho under irrigation with saline water (3.4 dS m-1). The treatments, with inter-row distance of 2 m, were distributed in randomized blocks, with four replications of 12 plants per plot, in a 4 × 2 factorial scheme, corresponding to intra-row distances of 3, 6, 9 and 12 m for plants with and without pruned main stem, upon reaching the support system. The evaluated components were number of fruit harvested, production per plant, fruit yield and in the fruit pulp, the analyzed components were soluble solid content, titratable acidity, pH and soluble solid content/ titratable acidity ratio. The interaction between the factors studied significantly affected the number of fruit harvested, production per plant, solids content and titratable acidity. The fruit yield was influenced by the two isolated factors, but the pH of the pulp responded only to the intra-row plant spacing, and the solids content/ titratable acidity ratio was not influenced by any of the sources of variation studied. Increasing the distances intra-row raises the production per plant, but reduces fruit yield. Plants pruned on the main stem have higher fruit yield. Irrigation with restrictive water quality to agriculture did not inhibit the productive capacity of yellow passion fruit access Guinezinho and did not impair the chemical quality of the fruits.   Keywords: Guinezinho access, planting density, Passiflora edulis Sims.

Objectives: To evaluate in vitro the endogenous pH, titratable acidity and total soluble solid content (TSSC) of mouthwashes available in the Brazilian market.Methods: The study sample was composed of 10 commercial brands of mouthwashes based on different active ingredients: Cepacol®, Clinerize®, Equate®, Listerine Cool Citrus®, Oral-B®, Periogard ®, Peroxyl®, Plax Overnight®, Prevident 220® and Sanifill®. The experiments were performed in triplicate. The endogenous pH was evaluated by potentiometry, titratable acidity was evaluated by the addition of 0.1N KOH increments to the mouthwashes, and TSSC readings were performed by Brix refractometry using the Abbé refractometer.Results: pH values ranged from 3.56 (Peroxyl®) to 7.43 (Cepacol®) and three mouthwashes presented pHs below 5.5. The titratable acidity values ranged from 0.007 (Periograd®) to 0.530 (Prevident ®). Oral B® and Clinerize® presented the lowest (4.7%) and the highest (23.70%) TSSC, respectively.Conclusions: Some of the mouthwashes evaluated in this study presented low endogenous pH, even below the critical value for enamel dissolution (pH<5.5), high titratable acidity and high TSSC, and may be potentially erosive to the dental tissues if not properly used.

More recently, functional foods or food supplements which can protect humans from oxidative stress and several diseases have attracted worldwide interest. Among functional foods, fruits were given special attention, particularly wild edible fruits (neglected or underutilized fruits). There are various neglected and underutilized fruit tree species grown in Turkey solely. They could be exploited directly as foods, or used to obtain valuable natural compounds and derivatives. Rose hip (Rosa spp.) is one of them. The aim of the study is to determine some fruit characteristics of promising rose hip selections from Bolu province in the western part of Turkey. In the selection study, around 100 wild growing rose hip plants were investigated and among them 9 promising genotypes were selected based on rose hip selection criteria. The fruit mass, fruit flesh ratio, soluble solid content, titratable acidity, total dry matter and vitamin C content of these selected nine genotypes ranged from 1.40-2.77 g, 64.92-82.83%, 24.10-30.50%, 0.04-1.55%, 32.44-56.94% and 332.42-1603.52 mg/100 g respectively. Among the 9 promising genotypes, two genotypes had high, two genotypes had medium and five genotypes had low level of thorn.

Some of the key components that contribute to the acceptance of high-quality fresh mangoes by consumers are its flavour, odour, texture and chemical constituents that depend mainly on level of maturity. In the European market, the demand for tree-ripened fruit has increased in recent decades. Nevertheless, the qualitative response and the marketable characteristics of tree-ripened mango fruit grown in the Mediterranean area are not yet studied. Tree-ripened fruits of cv Keitt, Glenn, Osteen, Maya, Kensington Pride and Tommy Atkins were submitted to analytical (fruit weight, transversal diameter, longitudinal diameter, flesh firmness, total soluble solid content, titratable acidity, seed weight, peel weight, percentage of flesh and fibre, ash content, fat content, carbohydrate content, riboflavin, niacin, thiamin, K, Na, Ca, Mg, Fe, Cu, Mn and Zn contents, ascorbic acid and vitamin A) and sensory evaluations. Significant differences were observed for sensory and physicochemical characteristics in a cultivar-dependent manner. The mango Keitt, in addition to its interesting physicochemical traits, content of protein and vitamin, has a higher sensory appeal. Glenn fruit showed more suitable weight, flesh firmness, soluble solids, vitamin content, total antioxidant activity and total polyphenolics content; Maya had the lowest titratable acidity and the highest soluble solid content, whereas Tommy Atkins revealed preferable ground colour, total antioxidant activity, and vitamin B2 and vitamin C contents. Tree-ripened fruits grown in the Mediterranean climate show interesting peculiarities in regard to fresh market requirements. The analytical-sensory approach established a qualitative characterization of the six observed cultivars.
