The ethylene action inhibitor 1-methylcyclopropene (MCP) reduces the rate of ripening of many apple and pear cultivars. The longevity of MCP responses induced by a single application at harvest is dependent in part on MCP treatment concentration and post-application storage conditions. Experiments were conducted using several apple and pear cultivars to evaluate the efficacy of repeated application to prolong the duration of MCP responses. Fruit were treated with MCP at harvest then stored in air at 0 °C. After various storage durations, MCP was reapplied at the same or higher concentrations. Control fruit not exposed to MCP were stored at the same temperature in either air or a controlled atmosphere (CA). Reapplication prolonged MCP responses compared to fruit treated only at harvest and fruit quality after storage was similar to that of fruit stored in CA. Reapplication was most effective when fruit ethylene production was below 0.1 μL·L–1 at the time of reapplication. The use of low concentration MCP treatments at harvest may allow for more predictable ripening of fruit after storage, particularly for pear fruit where softening is desired.

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.

`Bartlett' and `d'Anjou' pear fruit were treated after harvest with MCP at 0, 0.01, 0.1 or 1 mL•L-1 and then stored at 1 °C. After storage, half of the fruit was continuously exposed to 10 mL•L-1 ethylene for 7 days in a flow-through system at 20 °C. A treatment concentration effect was evident for both respiration and ethylene production, all MCP concentrations reduced respiration and ethylene production by `d'Anjou' and `Bartlett' fruit compared to controls. Fruit quality changes in `d'Anjou' and `Bartlett' fruit were delayed by MCP treatment. Firmness and titratable acidity were higher through 4 months storage for `Bartlett' fruit treated at the two higher MCP rates. After 2 months, `Bartlett' fruit treated at the two higher MCP rates remained green, but, after 4 months, all fruit were yellow. Loss of firmness and titratable acidity was also reduced following MCP treatment of `d'Anjou' fruit. Yellowing of `d'Anjou' fruit was prevented by MCP treatment, even when fruit were exposed to ethylene after removal from storage. Poststorage ethylene exposure did not overcome the effects of MCP. Development of superficial and senescent scald was prevented by MCP treatment.

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.

The objective of this study was to investigate the effects of rapid consecutive 1-methylcyclopropene (1-MCP) treatments on apple quality and disorders in storage. ‘McIntosh’ and ‘Spartan’ apples were harvested twice from commercial orchards and 1-MCP (1 μL·L−1) was applied postharvest either 1 day after harvest or 1 and 2 days after harvest. Similar fruit from both cultivars were also not treated with 1-MCP, plus an additional treatment of 2 μL·L−1 (double rate) 1-MCP was used on ‘McIntosh’. Fruit were held in either air storage at 0.5 °C for three or six months or in controlled-atmosphere (CA) storage for six or nine months. Overall, 1-MCP treatment improved firmness and acidity retention and reduced internal ethylene in both cultivars. However, ‘Spartan’ stored in CA often maintained these attributes without 1-MCP. ‘McIntosh’ apples treated twice with 1-MCP were often firmer than those treated just once. All 1-MCP treatments substantially reduced superficial scald and there was no difference in scald incidence among the treatments. Core browning was generally reduced by 1-MCP, but fruit treated once with 2 μL·L−1 or twice with 1 μL·L−1 1-MCP sometimes had higher incidence than fruit treated only once with 1 μL·L−1. ‘Spartan’ treated twice with 1-MCP also had higher incidence of internal browning after nine months. 1-MCP increased the incidence of external CO2 injury in ‘McIntosh’ from the first harvest, with fruit treated with 2 μL·L−1 having the highest incidence after six months of CA storage and those treated once with 1 μL·L−1 having the highest incidence after nine months. Storage rots were greatest after six months of air storage and 1-MCP treatments usually reduced the incidence, regardless of treatment. These results suggest that using more than the traditional single application of 1 μL·L−1 1-MCP may improve firmness retention, but there is also some risk associated with increased disorders, especially when storing apples long-term, such as for six months in air or nine months in CA storage.

The efficacy of 1-methylcyclopropene (1-MCP) in maintenance of apple fruit quality can differ depending on apple cultivar, ethylene content at harvest, 1-MCP concentration, the interval between harvest and 1-MCP application, and the number of applications. In this study, we investigated whether the 1-MCP concentration and its application frequency differently affected fruit quality attributes of the two new apple cultivars ‘Arisoo’ and ‘Picnic’. The fruits were treated with 1-MCP (as single or double treatments) at the rate of 0 μL L−1 (control), 0.5 μL L−1, 1 μL L−1, 0.5 + 0.5 μL L−1, and 1 + 1 μL L−1 for 18 h, and they were stored at 0 °C up to six months. Comparatively, the fruit qualities of 1-MCP treated fruits were higher than that of the control during cold storage, with a higher suppression of internal ethylene content and a slower reduction of titratable acidity in 1-MCP treatments than the controls throughout the cold storage in both cultivars, regardless of the concentration and number of applications. Reduction of fruit firmness and soluble solid contents were maintained by single application of 0.5 μL L−1 1-MCP in ‘Arisoo’ apple, while double application of 0.5 + 0.5 μL L−1 was needed in ‘Picnic’ cultivar. The effective concentration for weight-loss reduction was found to be the single application of 1 μL L−1 1-MCP in both ‘Arisoo’ and ‘Picnic’. Conclusively, 1-MCP as single treatment at the rate of 0.5 μL L−1 could be sufficient in inhibiting ethylene action and maintaining fruit quality losses during cold storage, particularly in ‘Arisoo’. However, double application of 1-MCP might be necessary for some quality attributes in ‘Picnic’ apple.

Abstract Background:Selenium (Se) is an essential trace element for both animals and plants. Se treatment can increase fruit Se concentration and shelf life. However, the mechanism underlying Se-delayed fruit ripening is still unclear.Results:In this research, two groups of Se (A and B treatments) were used to treat ‘Nanhong’ pear fruit. The results showed that these treatments could greatly increase the Se content but decreased the titratable acid content. Treatment A significantly decreased ethylene production, and the key genes controlling ethylene production, PuACSs and PuERF2, were inhibited by Se treatment. In addition, treatment A significantly decreased the stone cell content, and one lignin biosynthesis gene, PuC4H, was downregulated by treatment A.Concusions:Se treatment increased the Se content in pear fruit. In addition, Se decreased ethylene production and the stone cell content. Moreover, the key genes for ethylene production (PuACSs and PuERF2) and lignin biosynthesis (PuC4H) were also inhibited by Se treatment.

Mature 'Barhi' dates (Phoenix dactylifera L.) were stored in air or under controlled atmosphere (CA) storage conditions with 5%, 10%, or 20% carbon dioxide concentrations (balance air) during storage at 0 °C. CA conditions extended date storability by maintaining fruit quality. Fruit quality was maintained for 26 weeks when stored in 20% CO2, 17 weeks in both 5% and 10% CO2, and 7 weeks in air. Treatment with 20% CO2 maintained fruit color, firmness, SSC%, total sugar content, and total tannins. CO2 treatment also reduced degradation of caffeoylshikimic acid (CSA), which is one of the major phenolic compound of date fruit. This study indicates that 'Barhi' dates could be stored under CA conditions in cold storage with good eating quality for 17 to 26 weeks.
