Many potential benefits of 1-MCP (1-methylcyclopropene) to manage fruit
quality during and/or after storage have been identified. The degree to which
ripening processes are inhibited and quality maintenance enhanced by 1-MCP is
dependent of several factors. Responses induced by 1-MCP increase with
concentration from 0.01 ìL L-1 to 1 ìL L-1 and saturation responses occur in 12 h
exposure when 1 ìL L-1 of 1-MCP is applied. In general, fruit temperature during
treatment was not critical at the tested concentrations and duration. Experiments
conducted with ?Delicious? and ?Gala? apples indicated that fruit harvested after
optimum maturity for long-term CA is benefited from use of 1-MCP. However, the
potential for long-term storage of late harvested fruit remains low compared to fruit
harvested earlier. The duration of responses induced by MCP can also be influenced
by an interaction between fruit maturity and treatment concentration. Riper fruit
may require higher MCP concentration (1 ìL L-1) for maximum duration of MCPinduced
responses. The length of the delay between harvest/cooling and treatment is
another critical factor determinant of 1-MCP efficacy. Experiments conducted with
?Granny Smith? and ?Gala? apples indicated that maximum control of fruit
softening, superficial scald and senescent breakdown is achieved by treatment as
soon after harvest as possible.
