Effect of Controlled Atmospheres and Environmental Conditions on the Physicochemical and Sensory Characteristics of Sweet Cherry Cultivar Satin

Sweet cherry is a highly appreciated seasonal fruit with a high content of bioactive compounds; however, this highly perishable fruit has a relatively short shelf-life period. Here, we evaluated the evolution of the physicochemical and sensory qualities of sweet cherries (Prunus avium (L.) cv. Satin) under different storage conditions, namely at a Farmers’ Organization (FO) and in a Research Centre (RC) under normal and four different conditions of controlled atmosphere for 49 days. Additional parameters were monitored, such as rotten fruit incidence and stem appearance. Temperature was the factor that most influenced the fruit quality changes over the study time. In fact, fruits stored at higher mean temperatures showed higher weight loss, higher variation in CIE-Lab colour parameters, higher firmness loss, and browner and more dehydrated stems and were less appealing to the consumer. Controlled atmosphere conditions showed a smaller decrease in CIE-Lab colour parameters and lower weight loss. The incidence of rotting was very low and was always equal or lower than 2% for all conditions. Thus, RC chamber conditions were able to sustain fruit quality parameters over 28 days under normal atmosphere conditions and 49 days under controlled atmosphere conditions.

Earliness is also very important in addition to yield and fruit quality for more profitable production in sweet cherry cultivation. Therefore, some preparats are applied to get flowering even earlier in Kemalpaşa District of Izmir province, where sweet cherry fruits from Turkey are harvested the earliest. In this study, it was aimed to determine the effects of different treatments in the pre-flowering period on flowering and fruit quality of sweet cherry fruits. The study was carried out in the 2018 production year in a sweet cherry orchard established with the "0900 Ziraat" (Prunus avium L.) variety grafted on the "idris" (Prunus mahaleb) rootstock belonging to a producer in Kemalpaşa district of Izmir province. Approximately 30 days before flowering, Bud Feed 20 (BF20), 40 (BF40) and 60 mL L-1 (BF60) doses with Sett (3 mL L-1), Erger (50 mL L-1) + CaNO3 were treated to the sweet cherry trees from the leaf. The trees that are sprayed only with water were considered as control. Branches of similar size were selected from 4 different directions of the trees to determine flowering in sweet cherry trees, and the number of flowers bloomed on the branches recorded for 2-day intervals from March 17, when the first flowering was observed until the flowering was completed. The sweet cherry trees treated with BF40 + Sett, BF60 + Sett, and Erger + CaNO3 had the flowering 6-7 days and full bloom 7-8 days before compared to the control trees. The last flowering time of BF60 + Sett treated sweet cherry trees was 8 days earlier than the control trees, and 6 days earlier than the other treatments. It was determined that the weight and diameter of the fruits in BF60 + Sett and Erger + CaNO3 treated sweet cherry trees were partially higher than the control, while the other quality parameters were similar. The results showed that BF60 + Sett, Erger + CaNO3 and BF40 + Sett treatments were effective in the early flowering of sweet cherry fruits.

Sensory Data

Sweet cherry (Prunus avium L.) is a fruit appreciated by consumers for its well-known physical and sensory characteristics and its health benefits. Being an extremely perishable fruit, it is important to know the unique attributes of the cultivars to develop cultivation or postharvest strategies that can enhance their quality. This study aimed to understand the influence of physicochemical characteristics of two sweet cherry cultivars, Burlat and Van, on the food quality perception. Several parameters (weight, dimensions, soluble solids content (SSC), pH, titratable acidity (TA), colour, and texture) were measured and correlated with sensory data. Results showed that cv. Van presented heavier and firmer fruits with high sugar content. In turn, cv. Burlat showed higher pH, lower TA, and presented redder and brightest fruits. The principal component analysis revealed an evident separation between cultivars. Van cherries stood out for their sensory parameters and were classified as more acidic, bitter, and astringent, and presented a firmer texture. Contrarily, Burlat cherries were distinguished as being more flavourful, succulent, sweeter, and more uniform in terms of visual and colour parameters. The results of the sensory analysis suggested that perceived quality does not always depend on and/or recognize the quality parameters inherent to the physicochemical characteristics of each cultivar.

The Impact

Late pear cultivars, such as ‘Conference’, can be stored for a long period if kept in good storage conditions. A three-year study (2011–2013) compared the impact of six-month storage using four technologies—normal atmosphere, normal atmosphere + 1-methylcyclopropene (1-MCP), controlled atmosphere, and controlled atmosphere + 1-MCP—on the quality parameters of ‘Conference’ pears, such as mass loss, firmness, total soluble solids, acidity, antioxidant capacity, and the incidence of diseases and disorders. Additionally, the study analysed different storage conditions in terms of profitability, based on the market prices for pears in the seasons during which the pears were stored. The storage conditions had a very strong influence on the fruit quality parameters, and were found to affect most visibly the mass loss and the incidence of postharvest diseases and disorders. The storage of ‘Conference’ pears for 180 days in normal atmosphere is not economically viable, even if the fruit is subjected to 1-MCP treatment; at the same time, it is profitable to store ‘Conference’ pears in controlled atmosphere for the same period, no matter whether 1-MCP was applied or not.

Abstract The work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.) that were found in different Slovak regions. The experimental work has been performed during two years, 2014 and 2015. The following characteristics according to the descriptor list of subgenus Cerasus were evaluated - period of flowering and ripening, morphological characteristics of the flowers, fruit size, fruit weight, and quality parameters. The results showed high variability of evaluated accessions. From the 13 surveyed localities, the most valuable accessions were found in the locality Hornį Streda - places Čachtice, Krakovany, Nitra, and Brdárka. During the collecting expeditions, 170 accessions of sweet cherry, with fruit of the different quality were found. The most interesting accessions were grafted onto rootstocks with different intensity of growth (Prunus avium L., Prunus mahaleb L., and ‘Gisela5’). Some of the selected cherry accessions can be used for commercial growing after tests, while some of them can be used only for collection of genetic resources and as potential genitors in breeding programmes.

The objective of this study was to evaluate the effect of controlled atmosphere (CA) on quality preservation of ‘Laetitia’ plums, mainly on internal breakdown, in order to determine the best CA storage conditions. Two experiments were carried out one in 2010, and another in 2011. In 2010, besides cold storage (CS; 21.0 kPa O2 + 0.03 kPa CO2), the fruits were stored under the following CA conditions (kPa O2+kPa CO2): 1+3, 1+5, 2+5, 2+10, and 11+10. In 2011, the fruits were stored under CS and CA of 1+0, 1+1, 2+1, and 2+2. The fruit stored under different CA conditions had lower respiration and ethylene production, better preservation of flesh firmness, texture and titratable acidity, lower skin red color, and lower incidence of skin cracking than the fruit in CS. In 2010, the fruit under CA with 2+5, 1+5, and 1+3 had a pronounced delay in ripening, although it exhibited a high incidence of internal breakdown. In 2011, the CA conditions with 2+1 and 2+2 provided the best delay in ripening and a reduced incidence of internal breakdown. The best CA condition for cold storage (at 0.5°C) of ‘Laetitia’ plums is 2 kPa O2 + 2 kPa CO2.

‘Cristalina’ and ‘Skeena’ sweet cherry cultivars (Prunus avium L.) on Gisela 6 (Prunus cerasus × Prunus canescens) rootstock planted in 2005 were maintained since 2006 in a randomly blocked split-split plot experimental design with six blocks of two irrigation frequency main plot treatments within which two cultivar subplots and three soil management sub-subplots were randomly applied. The focus of this study was the growth, yield, and fruit quality response of sweet cherry to water and soil management over three successive fruiting seasons, 2009–11, in a cold climate production area. The final 2 years of the study period were characterized by cool, wet springs resulting in low yield and yield efficiency across all treatments. Soil moisture content (0- to 20-cm depth) during the growing season was often higher in soils that received high-frequency irrigation (HFI) compared with low-frequency irrigation (LFI). HFI and LFI received the same amount of water, but water was applied four times daily in the HFI treatment but every other day in the LFI treatment. Consequently, larger trunk cross-sectional area (TCSA) and higher yield were found on HFI compared with LFI trees. Soil management strategies involving annual bloom time phosphorus (P) fertigation and wood waste mulching did not affect tree vigor and yield. Increased soluble solids concentration (SSC) occurred with LFI. Decreased SSC occurred with delayed harvest maturity in trees receiving P fertigation at bloom. The largest fruit size was correlated for both cultivars with low crop loads ranging from 100 to 200 g fruit/cm2 TCSA. Overall cool, wet spring weather strongly affected annual yield and fruit quality, often overriding cultivar and soil and water management effects.
