Résumé

To determine if postharvest treatments of 1-MCP retard the senescence of highbush blueberries (Vaccinium corymbosm) removed from storage, 'Burlington' (early) and 'Coville' (late) fruit were harvested from four experimental sites and treated for 24 hours at 20 °C with 0 (control), 25 (low), 100 (medium), or 400 (high) nL.L-1 of 1-MCP. All fruits were then stored in a controlled atmosphere of 10-15 kPa O2 and 10 kPa CO2 at -1 to 1 °C for 4, 8, and 12 weeks, followed by a 20 °C shelf life of up to 20 days. During the shelf-life period immediately after harvest and those following each storage removal, percent marketable fruits (PMF) was calculated daily as: (fruit in good condition)/(total berry number) x 100. Changes in PMF were not affected by 1-MCP treatment. Hence, the authors concluded that 1-MCP at rates of up to 400 nL.L-1 does not alter the shelf-life quality of the highbush blueberry cultivars tested.
