The present study evaluated how post-harvest treatments with 1-methylcyclopropene (1-MCP) or methyl jasmonate (MJ) impact ?Fuji? and ?Braeburn? apple fruit tolerance to controlled atmosphere (CA) storage conditions. Fruit harvested from a commercial orchard in north central Washington were cooled to 0.5°C within 36 h of harvest and then stored in air or CA with 2 kPa O2 0.05 kPa CO2; 0.25 kPa O2 0.05 kPa CO2 or 2 kPa O2 3 kPa CO2 for up to 6 months. Fruit were treated with 2 mM MJ or 1 μlL-1 1-MCP at harvest. Both CA conditions and 1-MCP treatment reduced ethylene production, improved maintenance of firmness and titratable acidity and reduced incidence of core flush during long-term storage compared with untreated fruit stored in air. Treatment with 1-MCP was as or more effective than low CO2-CA storage for reducing ethylene production and preservation of firmness and acidity for both cultivars. ?Fuji? apples stored in 3 kPa CO2 developed internal browning (CO2-injury) while fruit stored in 0.25 kPa O2 with 0.05 kPa CO2 or air did not, regardless of 1-MCP treatment. ?Braeburn? apples also developed internal browning during air- or CA-storage, regardless of CO2 concentration. Severity of browning in ?Fuji? and ?Braeburn? apples stored in 3 kPa CO2 was not altered by previous 1-MCP treatment. However, browning severity increased by the 1-MCP treatment when ?Braeburn? fruit were stored in air or low CO2 CA. Treatment with MJ reduced severity of CO2-injury in fruit of both cultivars stored in high CO2 CA. The treatment with 1-MCP and storage in air or CA with 2 kPa O2 and low (≤0.05 kPa) CO2 may be a practical strategy for maximum retention of firmness and acidity with minimum development of CO2-injury in susceptible cultivars.
