Popis: 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.
