Eight recently introduced strawberry genotypes ‘Chambly’, ‘Clery’, ‘Darselect’, ‘Delia’, ‘Harmonie’, ‘Matis’, ‘Sallybright’, ‘Salsa’ and ‘Senga Sengana’ (standard cultivar) were evaluated at the Polli Horticultural Research Centre of the Estonian University of Life Sciences, Institute of Agricultural and Environmental Sciences. Phenology, winter hardiness, strawberry blossom weevil (Anthonomus rubi) injury, yield, fruit weight, soluble solids, sugar, acid and ascorbic acid content of the fruit were determined. Genotypes more suited to the Estonian climate conditions are the winter hardy, late-yielding cultivars ‘Salsa’ and ‘Harmonie’. ‘Salsa’ has a good, high quality yield with large attractive fruit. The fruit of ‘Harmonie’ contains much ascorbic acid, but the sugar-acid ratio is less balanced. Early genotypes ‘Chambly’, ‘Clery’, ‘Darselect’, ‘Delia’, ‘Sallybright’ and the late genotype ’Matis’ have a lower yield than the standard cultivar ‘Senga Sengana’.

Chilling injury in cucumber is the major issue under low temperature storage, which substantially affects cosmetic quality and market value of fruits. Present study was aimed to assess the effect of L-arginine to alleviate surface pitting caused due to chilling injury and response of various quality attributes during cold storage (5 ± 1 °C; RH 90 ± 5%). Cucumber cv. ‘7003’ fruits were treated with different concentrations of L-arginine (0.0, 0.5, 1.0 and 1.5 mM) and stored for 16 days. Fruits were removed at 4 days storage interval followed by 1 day of conditioning (22 ± 2 °C) before quality analysis. Visual quality, fruit colour, decay, fruit weight loss, firmness, chilling injury (CI), electrolyte leakage, taste, texture, flavour, aroma, soluble solids content (SSC), titratable acidity (TA), sugar: acid ratio (SSC/TA ratio) and ascorbic acid content were measured for cucumber fruits. Overall, it was noted that L-arginine treated fruits showed lower fruit weight loss and electrolyte leakage, and maintained taste, texture, aroma, SSC, and sugar: acid ratio during storage. Fruits treated with 0.5 mM L-arginine had significantly reduced chilling injury and decay, maintained fruit colour, firmness and flavour, and displayed higher ascorbic acid content compared with control. Conclusively, pre-storage application of L-arginine (0.5 mM) can be employed as promising technique to alleviate postharvest chilling injury and maintain fruit quality of cucumber under cold storage.

Extraction of tropical fruit juice using simple, efficient, and environmentally friendly technologies is gaining importance to produce high quality juices. Juice from pink-fleshed guava, pink-fleshed pomelo, and soursop was extracted using direct and indirect thermosonication methods by varying intensity, time, and temperature, and compared to those extracted using water bath incubation. Improvised models of juice yield, ascorbic acid, and total soluble solids responses were generated by eliminating insignificant model terms of the factors in full quadratic model using backward eliminating procedure. Main effects, 3D, or 4D plots for each response were developed based on factors that influenced the response. Results showed that the best extraction method for guava and pomelo juices were within indirect thermosonication method of 1 kW, 55 °C and 30 min, and 2.5 kW, 54 °C and 23 min, respectively. Direct thermosonication method at 10% amplitude, 55 °C for 2 to 10 min was more suitable for soursop juice. Thermosonicated extraction of tropical fruit juice can improve its juice yield, ascorbic acid content, and total soluble solids content.

This study aimed to evaluate the postharvest behavior of peach cv. Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD) . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.

'Aurora-1' peaches establishes an interesting alternative as a minimally processed product, due to its characteristics like flavor, color, smell, and also because of its handling resistance. However, it has a short shelf life after a fresh-cut due to enzymatic browning and stone cavity collapse. The main purpose of this research was to test the additive with antioxidant effect to prevent browning in minimally processed 'Aurora-1' peaches. The minimal processing consists of washing, sanitizing, peelings and fruit stone extraction. After that, longitudinal cuts were made to obtain eight segments per fruit. The slices were immersed into the following treatment solutions: control (immersion in 2% ascorbic acid); 2% ascorbic acid + 2% calcium chloride; 1% sodium isoascorbate; 1% citric acid; 1% L-cysteine hydrochloride. The products were placed into rigid polystyrene trays branded MEIWA M-54, covered with 14 µm PVC film (OmnifilmTM) and kept in cold storage at 3ºC ± 2ºC and 65% RH for twelve days, and evaluated each three days. Appraised variables were appearance, soluble solids, titratable acidity, soluble carbohydrates and reducing sugars, total and soluble pectin, ascorbic acid, and peroxidase and polyphenol oxidase enzyme activity. L-cysteine gave to the minimally processed products a shelf life of twelve days, limmited by off-flavor. The treatment with ascorbic acid was efficient to maintainthe ascorbic acid content, with a shelf-life of nine days, limited by enzymatic browning.

The tomato fruit is rich in antioxidant compounds and has great nutritional and economic importance, annually promoting research on the nutritional and productive characteristics. The present study aimed to evaluate whether foliar application of commercial products based on growth regulators [auxin, cytokinin and gibberellin (Ax+CK+GA)], micronutrients [cobalt and molybdenum (Mi)] and mixtures of macro and micronutrients [nitrogen, boron, copper, molybdenum and zinc (Ma+Mi)], isolated and in combination, increase productivity and improve the post-harvest quality of tomato fruits (Predador F1). The experiment design used randomized blocks, with seven treatments and four repetitions, which were (T1) control; (T2) Ax+CK+GA; (T3) Ma+Mi; (T4) Mi; (T5) Ax+CK+GA + (Ma+Mi); (T6) Ax+CK+GA + Mi; and (T7) Ax+CK+GA + Mi + (Ma+Mi). The variables production, precocity, soluble solids content (SS), titratable acidity (TA), ratio (SS/TA), pH, total soluble sugars, ascorbic acid and weight loss were evaluated. The Ax+CK+GA application, isolated or in combination with Ma+Mi, promoted the precocity, and the use of isolated Ax+CK+GA and Mi improved the tomato plant productivity. The growth regulators, macro and micronutrients, isolated or in combination, increased the ascorbic acid content in the fruits.
