Resumen:
Senescence of detached spinach leaves either untreated or treated with 0.1 or 1.0LL−1 1-MCP has been
investigated. 1-MCP treated leaves had higher chlorophyll content and photosystem II potential quantum
yield (Fv/Fm) and lower solute leakage than untreated leaves after storage in darkness at 23 ◦C for 6 d,
indicating a delay of senescence. Ethylene productionwasincreased in spinach supplemented with1-MCP
after 3 d storage and then declined to the rates of untreated leaves. 1-MCP treated spinach had higher
ascorbic acid and glutathione concentrations, and a low oxidised/reduced ratio for both antioxidants.
Accumulations of ammonium and protein degradation were reduced by 1-MCP. The results presented
here indicate that inhibition of ethylene sensitivity can be successfully used to extend the postharvest
life of spinach leaves.
