The behavior of apples treated with the ethylene biosynthesis inhibitor 1-MCP in the post-harvest period

Abstract

Stable and high-quality apple harvests must be accompanied by the use of progressive methods of fruit preservation in the post-harvest period, which ensure fruit resistance to disorders caused by fungal diseases due to the application of growth regulators based on 1-methylcyclopropene. The apple fruits studied were of the Gala Dark Baron variety, grown on the M9 rootstock, in the intensive culture system. To determine the effectiveness of treatment with ethylene biosynthesis inhibitors, the following experimental scheme was developed: 1. Control, no treatment; 2. Fitomag, 0.44 g/m3 ; 3. Grand Fresh, 60 g/ m3 ; 4. Grand Fresh, 68 g/m3 . The fruits of the control and treated variants were placed in rooms with a normal atmosphere (CO2 - 0.03%; O2 - 21%). Storage temperature 0...+1 0 С and humidity 92-95 %. The storage period was 150 days.
