Postharvest strategy combining maturity and storage temperature for 1-MCP-treated peach fruit

摘要

Maturity, storage temperature, and postharvest treatment are all important factorsthat determine how postharvest storage affects qualities that make peaches attractiveto consumers. In this study, the combined effects of maturity stage (as determinedby IAD value; M1: 1.0 ～ 1.4, M2: 0.6 ～ 1.0 and M3: 0.2 ～ 0.6), treatment with orwithout 1-methylcyclopropene (1-MCP), and storage at different temperatures (5℃,10℃, and 20℃) were measured in “Hujingmilu” peaches. Our results showed thattreatment with 1-MCP helps to maintain fruit postharvest quality, but efficacy is influencedby postharvest factors. Principal component analysis (PCA) showed that1-MCP application increases the storage potential of fruit and has the potential to makefruit harvested at middle maturity (M2) more acceptable to consumers. In addition,low maturity fruit (M1) treated with 1-MCP are more suitable for long-term transportationin cold storage.
