1-MCP 및 수확 후 처리가 복숭아(Prunus persica Batsch) ‘장호원황도’ 저장 유통 중 품질에 미치는 영향

This study was conducted to investigate the effect of 1-MCP, an ethylene action inhibitor, and several postharvest treatments including ethylene scrubbing on fruit quality and respiration for keeping marketability in ‘Janhowon Hwangdo’ peach (Prunus persica Batsch). 1-MCP at the rate of 1.0 μLㆍL?¹ showed best results in maintenance of fruit firmness and external appearance such as skin color. The ethylene production was strongly reduced by 1-MCP treatment at 0.5 or 1.0 μLㆍL?¹ but respiration rate was only suppressed at 1.0 μLㆍL?¹ during 6 days of shelf life at 20℃. Mature fruits (harvested 1 week before full commercial maturity) were much highly responsive to 1.0 μLㆍL?¹ of 1-MCP compared to those of commercial maturity. At the concentration of 0.5 μLㆍL?¹ of 1-MCP did not affect fruit marketability compared to untreated control. Beneficial effects of carbon ceramic as an ethylene scrubber were also found such as delay of firmness loss and deterioration of external appearance at 10℃, but these positive effects on fruit quality remained for only 5 days. The application of ethylene scrubber on the shipping carton boxes was effective on keeping firmness of immature fruit pretreated with 1-MCP when compared with mature fruit.
