Abstract

Two experiments were conducted to evaluate the relative effects of controlled atmosphere (CA) associated with 1-methylcyclopropene (1-MCP; 1.0 μL L−1), induction of mass loss (IML; 2%), and low ethylene (LE; <0.04 μL L−1 of C2H4) on the quality preservation of ‘Laetitia’ plums. In experiment 1 (2010), the treatments evaluated were cold storage (CS; 21.0 kPa O2 + <0.03 kPa CO2), CA1 (1 kPa O2 + 1 kPa CO2), CA1 + 1-MCP, CA1 + IML, and CA1 + LE. In experiment 2 (2011), the treatments evaluated were CS, CA2 (2 kPa O2 + 2 kPa CO2), CA2 + IML, and CA2 + 1-MCP. In both experiments, the fruit were stored at 0.5 ± 0.1°C and 96 ± 2% RH. CA storage delayed fruit ripening in both atmosphere conditions evaluated and reduced the internal browning of the ‘Laetitia’ plums, particularly in CA2. 1-MCP, LE, and IML had additional effects to CA1 on preserving flesh consistency. 1-MCP, irrespective of the CA condition, and IML, in CA1, reduced internal browning. CA1, regardless of the complementary technologies, reduced the incidence of decay and fruit cracking.
