Résumé

Plums harvested in a pre-climacteric ripening stage were used. Three different doses of 1-MCP were used: 250, 500 and 750 ppb. Fruit were stored at 1°C. Weekly, samples from the cold chamber were analysed and then other lots were stored at 20°C to study shelf-life for 4 and 7 days. Results showed a strong inhibition of ethylene emission, especially during shelf life. This ethylene suppression was correlated with increased fruit firmness and reduced weight losses, the 750 ppb dose being the most efficient. With respect to colour changes, the effects of 1-MCP was shown after 3 weeks of cold storage. No significant differences were observed in titratable acidity, while total soluble solids increased in control plum compared with treated ones. Thus, 1-MCP could be used as an agrochemical to maintain quality during postharvest storage of plums, which usually have a very short shelf life.
