Responses of 'Bing' and 'Rainier' sweet cherries to ethylene and 1-methylcyclopropene.

'Bing' and 'Rainier' sweet cherry (Prunus avium) fruits treated with 1-methylcyclopropene (1-MCP) were stored at 20 deg C in air or at 35 micro litre litre-1 ethylene. Ethylene production by both 'Bing' and 'Rainier' fruits stored in air was transiently stimulated following 1-MCP treatments; however, there were no significant effects of 1-MCP on respiration rate. Exogenous ethylene stimulated respiration regardless of prior treatment with 1-MCP. Although 1-MCP treatment reduced the increase in 'Bing' respiration induced by ethylene, the reduction was less than reported previously for climacteric fruits. These results suggest that stimulation of sweet cherry fruit respiration by ethylene occurs via a process that may be independent of receptors to which 1-MCP binds. Postharvest changes in fruit colour and development of stem browning were not altered by 1-MCP treatment, and exogenous ethylene accelerated the development of stem browning regardless of prior treatment with 1-MCP.
