Abstract??

This? study? aimed? to? investigate? the? effects? of? 1-methylcyclopropylene? (1-MCP)? and? abscisic? acid (ABA) treatments on the postharvest tangerine variety Orah. The whole fruit was treated separately with 0.6 μL/L 1-methylcyclopropylene and 20 mg/L abscisic acid. The fruit was subjected to texture analysis, whereas fruit peel was obtained for microstructure observation. Correlation and principal component? analyses? showed? that? 1-MCP? treatment? could? maintain? a? good? peel? texture.? ABA treatment accelerated fruit senescence and caused the deterioration of textural properties of the fruit. The? data? showed? that? 1-MCP? treatment? maintained? the? integrity? and? compactness? of? the? peel structure. The? peel? of? the? fruit? treated? 1-methylcyclopropylene? also? had? a? uniform? thickness? after storing? at? ambient? temperature? for? 20? days.? The? peel? tissue? of? fruit? treated? with? ABA? was? more prone? to? collapse? and? structural? disorder.? These? findings? study? suggested? that 1-methylcyclopropylene? treatment? was? an? effective? way? to? prevent? the? deterioration? of? Orah tangerines.?
