Summary The role of postharvest application of 1‐Methylcyclopropene (1‐MCP) in modulating ‘Tegan Blue’ Japanese plum fruit ripening and quality under ambient and cold storage conditions was investigated. 1‐MCP‐treated fruit (0, 0.5, 1.0 and 2.0 μL L −1 ) were allowed to ripen at ambient temperature in Experiment 1, while in the second experiment the fruit were kept in cold storage (0, 3 and 6 weeks) before ripening. In both experiments, 1‐MCP treatment significantly delayed (2–8 days), suppressed (30–70%) the climacteric ethylene production, maintained higher fruit firmness (34–60%), titratable acidity, L* , chroma, hue angle of fruit skin and pulp, and reduced concentrations of soluble solids, ascorbic acid, total carotenoids and total anti‐oxidants as compared to the control. 1‐MCP (1.0 μL L −1 ) treatment suppresses and delays the climacteric ethylene production with acceptable fruit quality during ripening at ambient temperature and is effective in extending the storage life up to 6 weeks with minimal loss of plum fruit quality.
