Summary

CHANGES OF ACC LEVEL AND THE RATE OF ETHYLENE PRODUCTION IN APPLE FRUIT CV SPARTAN DURING STORAGE AT TWO O2 CONCENTRATIONS IN THE PRESENCE AND ABSENCE OF CO2 WERE DETERMINED. THE LOWEST ETHYLENE EVOLUTION ASSOCIATED WITH A LOW LEVEL OF ACC WAS FOUND IN FRUIT STORED IN 2% CO2 + 1% O2. AT 1% O2 WITHOUT CO2, APPLES PRODUCED AN AMOUNT OF ETHYLENE COMPARABLE TO THEABOVE ATMOSPHERE, BUT ALMOST 3 FOLD THE LEVEL OF ACC WAS FOUND DURING WHOLE STORAGE PERIOD. AT 3% O2, WITHOUT CO2, CONSIDERABLY MORE ETHYLENE WAS FOUND. PERHAPS A CONCENTRATION OF 3% O2 DID NOT DEPRESS THE CONVERSION OF ACC AS STRONGLY AS IN 1% O2 AND THE RATE OF ETHYLENE EVOLUTION CORRESPONDS TO THE AMOUNT OF FORMED ACC. THE PRESENCE OF A HIGH CONCENTRATION OF CO2 MAY STRONGLY INHIBIT ACC SYNTHESIS AND, CONSEQUENTLY, THE RATE OF ETHYLENE EVOLUTION.
