INTERMITTENT HIGH CARBON DIOXIDE TREATMENTS DURING COLD STORAGE OF KIWIFRUIT. EFFECT ON ETHYLENE SYNTHESIS.

Author(s) : NICOLAS J., ROTHAN C., MORAS P.

Summary

INTERMITTENT HIGH CARBON DIOXIDE (15%) TREATMENT (IHCT) REDUCED SOFTENING AND DELAYED ETHYLENE SYNTHESIS OF KIWIFRUIT STORED AT 0 DEG C. ELEVATED CARBON DIOXIDE SEEMS TO ACT MAINLY ON ACC (1-AMINO-CYCLOPROPANE-1 CARBOXYLIC ACID) CONVERSION TO ETHYLENE BY EFE (ETHYLENE FORMING ENZYME). BESIDES ITS FUNGISTATIC EFFECT ON BOTRYTIS, IHCT DELAYED EFE DEVELOPMENT IN KIWIFRUIT STORED 3 MONTHS AT 0 DEG C, COMPARED TO THE SHARP INCREASE OBSERVED FOR FRUIT STORED UNDER AIR. THESE RESULTS SUGGEST THAT CARBON DIOXIDE, IN ADDITION TO COUNTERACTING ACTION OF ETHYLENE, MAY EXERT AN EFFECT ON ETHYLENE SYNTHESIS VIA AREDUCTION IN EFE ACTIVITY AND DEVELOPMENT, DELAYING KIWIFRUIT MATURATION.
