This work was carried out to evaluate the effects of preharvest 1-methylcyclopropene (1-MCP, HarvistaTM) and postharvest 1-MCP (SmartFreshTM) treatments on the fruit quality attributes of cold-stored ‘Fuji’ (Malus domestica Borkh.) apples. Fruits were exposed to 0, 95, 125, or 250 mg･L-1 HarvistaTM at 3, 2, 1 weeks before harvest (WBH), and treated with 0 or 1 μL･L-1 SmartFreshTM at harvest. Fruit was then stored for up to 180 days at 0 ± 1°C. Fruit fresh weight, Hunter’s value a, internal ethylene concentration (IEC), flesh firmness, titratable acidity (TA), and soluble solids content (SSC) in fruit treated with HarvistaTM were not different from those of control fruit at harvest. During cold storage, flesh firmness and TA were higher in fruit treated with 250 mg･L-1 HarvistaTM at 2 and 3 WBH than in control fruit. IEC was 5.5-10.0% lower in fruit treated with 250 mg･L-1 HarvistaTM at 2 and 3 WBH compared with control fruit as storage duration progressed, while SSC was not affected. Furthermore, flesh firmness, TA, and IEC were affected neither by HarvistaTM nor HarvistaTM + SmartFreshTM treatments, compared with those fruit quality attributes at harvest. The correlation maps indicated that IEC was negatively correlated with firmness and TA, regardless of HarvistaTM application levels. In addition, positive correlations between fruit quality attributes were detected in treatments with 250 mg･L-1 HarvistaTM + SmartFreshTM. Therefore, the results suggest that with a single application of SmartFreshTM, a higher level of HarvistaTM application would help in retention of fruit quality attributes during cold storage.
