ABSTRACT‘Regina’ sweet cherry fruit (Prunus avium L.) harvested from trees grown on vigorous and semi-dwarfing rootstocks was stored in normal atmosphere (NA) at 8°C and 2°C, and in a controlled atmosphere (CA) 3% O2 + 5% CO2at 2°C for two weeks. At harvest time, the fruits differed in the measured quality parameters (firmness, soluble solids content - SSC, titratable acidity - TA) depending on the rootstock. The storage conditions and the rootstocks significantly influenced the fruit quality parameters after storage. Generally, reduced fruit firmness and TA, and higher SSC and SSC/TA ratio were observed at the end of the storage period. Among the rootstocks, the lowest soluble solids content was found in the fruit from trees on the vigorous F12/1 rootstock. The lower storage temperature decreased the SSC independently of the storage atmosphere composition. Firmer fruit was found in CA 2°C compared with the other two treatments. The greatest loss of weight was found after fruit storage in NA 8°C. The extent of fruit decay depended on the season, storage conditions and the rootstock. Storage in NA 8°C of the fruit grown on F12/1 rootstock resulted in the highest percentage of fungal decay. The best retention of the green colour of the peduncle was noted in CA 2°C. The findings on how the rootstocks affect sweet cherry fruit properties can be useful for sweet cherry breeding programmes, as well as for sweet cherry crop production and storage technologies.

Abstract The aims of this work were to determine which storage conditions can preserve the quince quality (Cydonia oblonga Miller, Rosaceae family), stored in three different rooms with controlled atmosphere (CA). Due to their reported high polyphenolic content in the fruit, three varieties of quinces, like Ekmek, Bereczhi and Tinella were stored and monitored for twelve months. During storage period, the following quality parameters were monitored: dry matter content (D.M.%), titratable acidity (TA), soluble solids (°Brix), firmness, antioxidant capacity and also content in total flavonoids and total polyphenols. After twelve months of storage, observations showed that quince from Tinella variety presented better quality parameters compared to quinces from Ekmek and Bereczhi varieties. As expected, keeping quinces in the presence of CO2content, respectively 2% and 5%, presented better physical and biochemical quality compared with those stored without CO2 (control).

`Bartlett' pears (Pyrus communis L.) tolerated up to 10 days of exposure to atmospheres containing 1.0%, 0.5%, or 0.25% O2 at 0, 5, or 10C without any detrimental effects on their quality attributes. The fruits also tolerated 4 to 6 days of exposure to air enriched with 20%, 50%, or 80% CO2 at the three temperatures. The beneficial effects of exposures to the O2-reduced or CO2-enriched atmospheres included reduction of respiration and ethylene production rates and retardation of skin yellowing and flesh softening. While 1.0% or 0.5% O2 and 20% CO2 did not increase ethanol and acetaldehyde contents, 0.25% O2 slightly increased and 50% or 80% CO2 dramatically increased the contents of these two volatiles in juice of the fruits. The effects of low O2 or high CO2 on the above attributes generally became more pronounced at the higher temperatures. The low O2 or high CO2 treatments did not significantly affect either soluble solids content or titratable acidity. Low O2 did not influence, but high CO2 slightly increased pH of the fruits.

Mango fruits `Criollo de Bocado' harvested at the mature-green stage were treated with a hydrothermic treatment of 55 °C for 3 min and stored for 20 days at temperatures of 10 ± 2, 15 ± 2 and 28 ± 2 °C. A randomized design 2 × 3 × 4 with three replications was used. Some chemical parameters were analyzed, such as total soluble solids content (% TSS), pH, tritatable acidity, and TSS/tritatable acidity ratio. TSS content increased with storage time at low temperature. The pH increased measurably with storage temperature, while tritatable acidity values results had inconsistent data.

The development of internal breakdown of South African Bulida apricots during cold storage, rendering the fruit unsuitable for canning, causes significant post-harvest losses. Regression models to predict internal post-storage quality using near infrared (NIR) spectroscopy and multivariate classification techniques were developed using NIR spectra of the intact fruit collected prior to storage and subjective quality evaluations performed after a cold storage period of four weeks. A correct classification rate of 69% was obtained using multivariate adaptive regression splines (MARS) compared to 50% obtained by soft independent modelling by class analogy (SIMCA). NIR regression models developed for soluble solids content (SSC) of intact fruit as well as for direct NIR measurements on the exposed fruit tissue gave similar results, thus confirming sufficient NIR light penetration into the intact fruit. The best prediction results were obtained when two spectral measurements per fruit (one on each half of the fruit), compared to single measurements, were used.

Plant Sci. 94: 1555–1558. ‘SPC136’ (Suite Note™) is a new early-season sweet cherry being released for commercial production by the Agriculture and Agri-Food Canada sweet cherry breeding program at Summerland, BC, Canada. Harvest timing in Summerland (Jul. 09) is similar to that of ‘Bing’ or ‘Van’ but fruit size is much larger (over 12 g). Fruit firmness, soluble solids content and susceptibility to rain splitting resemble those of other cultivars of similar harvest timing, but stem detachment force is higher. The trees are not self-fertile and bloom late in the cherry blossom season.

Fruit Respiration

Banana fruit respiration rates and quality parameters such as peel color, pulp pH and soluble solids content were examined at 14°C under a number of controlled atmosphere (CA) environments. CA conditions were 1%, 2%, 4%, or 8% oxygen with or without 5% carbon dioxide. Each treatment combination was also done with or without 50 μL·L–1 ethylene added to the atmospheres. Green banana fruit were either gassed with ethylene (triggered) or ungassed. One percent oxygen was too low to consistently give undamaged bananas. The addition of 5% carbon dioxide to the controlled atmosphere increased fruit respiration rate whereas air plus 5% carbon dioxide showed decreased respiration when compared to air control fruits. Green, triggered fruit partially ripened under the CA conditions. Pulp pH and soluble solids content changed in a normal ripening pattern, however peel color was poor. Addition of ethylene to the atmospheres advanced fruit ripening somewhat in all fruit. When green, ungassed bananas were placed under CA, the presence of ethylene in the atmosphere did not cause the bananas to turn yellow, although some changes in pH and soluble solids were detectable. In triggered fruit the presence of ethylene in the storage advanced ripening with higher oxygen concentrations promoting faster ripening. Bananas that have ripened under CA conditions are not as high quality as those ripened in air in terms of visual appearance.

The effects of prolonged ethylene exposure on external and internal quality parameters of tomato fruits were studied in order to explore the feasibility of its use as a nondestructive technique for screening immature and inferior quality fruit. `Agriset' and `CPT-5' tomatoes were hand harvested at Stage 1 (green) and held at 20°C and 50 ppm ethylene for 1-7 days. Each 24 hours, fruits reaching Stage 2 (breaker) were removed from C2H4 and transferred to 20°C air for subsequent ripening. Tomatoes were considered at edible maturity upon reaching full red-ripe stage and 4 mm deformation and final quality parameters were determined. For both cultivars, fruits which required prolonged C2H4 exposure to reach Stage 2 had lower overall visual appearance. `Agriset' tomatoes which required short exposure times to C2H4 (1 to 3 days) had somewhat higher quality than those requiring prolonged times (4 or 5 days). Days to reach edible maturity were 9.5 and 7.7, respectively. For the short exposure times, peel color was more intense (higher chroma value), while soluble solids content and total sugars were significantly higher (P = 0.05). Quality of `CPT-5' tomatoes was not adversely affected until requiring 6 or 7 days exposure to C2H4. Days to reach edible maturity decreased from an average of 12.5 to 11.0 for 1 to 5 or for 6 to 7 days exposure, respectively. For fruits requiring 7 days exposure, soluble solids content, total sugars and pH were significantly higher than for those reaching Stage 2 in fewer days. There were no significant differences in titratable acidity or ascorbic acid content for either cultivar.

High-quality cranberry (Vaccinium macrocarpon) fruit are required to fulfil the growing markets for fresh fruit. Storage losses of fresh cranberries are primarily the result of decay and physiological breakdown. Maximizing quality and storage life of fresh cranberries starts in the field with good cultural practices. Proper fertility, pest management, pruning, and sanitation all contribute to the quality and longevity of the fruit. Mechanical damage in the form of bruising must be minimized during harvesting and postharvest handling, including storage, grading, and packaging. In addition, water-harvested fruit should be removed promptly from the bog water. Following harvest, fruit should be cooled quickly to an optimum storage temperature of between 2 and 5 °C (35.6 and 41.0 °F). The development of improved handling, refined storage conditions, and new postharvest treatments hold promise to extend the storage life of fresh cranberries.

Preclimacteric McIntosh apples were maintained under low (average 6 ppm) C2H4 and high (average 1,570 ppm) C2H4 levels for 189 days at 3.3 °C. Subsequent analysis of the fruit revealed that the low C2H4 storage condition had maintained approximately 0.9 kg (2 lb.) greater firmness in the fruit than had the high C2H4 condition. This extra firmness persisted for more than a week at room temperature. Acidity levels and soluble solids content were increased slightly by the low C2H4 treatment. Low C2H4 treatment caused both a lower internal C2H4 content of the fruit and a lower level of C2H4 emission by the whole fruit than did storage in high levels of C2H4. The low C2H4 storage conditions reduced the incidence of core browning.

Abstract Fruits of the sweet cherry cultivar ‘Regina’ collected from trees growing on seven rootstocks were stored in a cold room at 2 °C with a normal (NA) and controlled atmosphere (15% and 20% CO2 and 5% O2—CA1 and CA2) for 2 weeks. The rootstocks on which the trees grew and the storage conditions significantly affected all fruit parameters tested during both years of the experiment. Fruit from Damil rootstock exhibited higher mean firmness than fruit from Colt rootstock. The effect of rootstocks on the value of soluble solids content (SSC) varied, wherein the fruits from Tabel Edabriz and Damil were characterized by high SSC mean content. The organic acids content (TA) was significantly lower after storage than during harvest time. Fruits from Tabel Edabriz trees were characterized by faster ripening, as was evident by the higher SSC to TA ratio. The amount of mass lost depended significantly and only on the storage conditions—sweet cherries from both CA combinations had the lowest mass losses. The percentage of fruits showing disease symptoms was largely dependent on the weather conditions in the orchard the year before the fruit harvest, as well as atmosphere composition and RH during fruit storage. Cold storage conditions with a high (20%) CO2 content are recommended for the short-term storage of sweet cherry fruits because they preserve fruit quality parameters: a low decrease in firmness, maintenance of a high SSC/TA ratio, a low percent of fungal infections, and good preservation of green color in the peduncle.
