چکیده انگلیسی


• 1-MCP was applied 2 d after harvest and again after 4 months of CA storage.
• Multiple 1-MCP applications improved firmness retention in ‘McIntosh’ and late harvested ‘Empire’ after 9 months of CA storage plus 7 days at room temperature.
• Incidence of storage disorders varied depending on cultivar and 1-MCP applications.

The objective of this study was to investigate the effects of multiple 1-methylcyclopropene (1-MCP) treatments on fruit quality and disorder development in apples, with a second 1-MCP treatment applied after several months of controlled atmosphere (CA) storage. ‘McIntosh’, ‘Empire’, and ‘Northern Spy’ apples were harvested from commercial orchards and cooled overnight to 3 °C. 1-MCP (1 μL L−1) was applied 2 d after harvest and then again to half of the fruit after 4 months of CA storage. ‘Northern Spy’ apples also received a single 1-MCP treatment after 4 months of CA storage. Similar fruit from all cultivars were also not treated with 1-MCP. ‘McIntosh’ and ‘Empire’ were held at 3 °C and ‘Northern Spy’ at 0 °C for 9 months in CA storage (2.5 kPa O2 + 2kPa CO2 for ‘Empire’, 2.5 kPa CO2 for ‘Northern Spy’, and 2.5 up to 4.5 kPa CO2 for ‘McIntosh’). Overall, 1-MCP reduced internal ethylene production, and improved firmness and acidity retention in all apple cultivars. The addition of a second 1-MCP treatment after 4 months of CA storage further improved firmness retention in ‘McIntosh’ and late harvested ‘Empire’ apples after 7 d at room temperature. ‘Northern Spy’ apples treated with 1-MCP had lower incidence of external CO2 injury, regardless of 1-MCP treatment timing. Multiple 1-MCP treatments had varying effects on the incidence of core browning; late-harvested ‘McIntosh’ treated twice with 1-MCP exhibited the highest incidence of core browning, while late-harvested ‘Empire’ treated twice had less core browning than those not treated. ‘Northern Spy’ treated only at harvest time had more core browning compared to those treated only or also after 4 months of CA storage and non-treated fruit. 1-MCP treatment had no significant effect on the incidence of internal browning in ‘McIntosh’ or ‘Empire’ apples. These results suggest that a second application of 1-MCP after 4 months of CA storage may improve firmness retention in some cultivars during holding at room temperature, but it can also have variable responses associated with susceptibility to disorders, especially when holding apples in long-term CA storage.
