Abstract

'Ooishiwase' plum (Prunus salicina L.) fruits were harvested at three pre-climacteric stages of ripeness (stages 1, 2, and 3) and treated with 1-methylcyclopropene (1-MCP, $1\;{\mu}L/L$) for 24 hours at $10^{\circ}C$ before storage to evaluate the effectiveness of 1-MCP in extending shelf-life at $10^{\circ}C$. Ethylene production and respiration rates were significantly lower after 1-MCP treatment compared to those of control fruit, throughout the entire storage period. Also 1-MCP delayed plum softening and color changes. However the chemical 1-MCP had no effect on fruit soluble solid content changes, the preservative 1-MCP is an effective tool for quality improvement in plums, and extension of shelf life of the fruit and plums can safely be harvested at stage 3 of ripening, at which time the most desirable organoleptic attributes have been developed.
