Popis: In order for the Japanese Plum to reach distant markets with adequate consumption quality, it is necessary to determine not only the best harvesting time but also the most appropriate postharvest technologies that allow the correct ripeness after the distribution process. This paper addresses the combined effect of the harvesting time (H1, H2 and H3) with or without 1-MCP (T and C) treatment and the postsharvest storage in different temperature regimes (0 °C, 8 °C and dual temperature regime, 0/8 °C). The ‘Songold’ plum was kept for 30 and 50 days in cold storage and at 20 °C for 5 days after that (shelf-life, SL). For each analysis date, physical and chemical quality parameters were established (weight loss, firmness, colour, total soluble solids and acidity), together with postharvest damage (chilling injuries and decay). In general, the 1-MCP reduced the firmness loss and colour changes (L* and b*), maintaining the acidity of the fruit at rates close to those of the ones at harvest. The use of 1-MCP allows us to market the fruit at a more advanced ripening stage and to store it at a higher temperature without quality loss. Chilling injuries (CI) were the most relevant damages, mainly in H2 at 8 °C after 50 + 5 days. 1-MCP appears to reduce the impact of CI but not decay.
