[In German. / En allemand.]

Author(s) : BACHMANN U.

Type of article: Article

Summary

THE TESTS SHOWED THAT SOME CONTROLLED ATMOSPHERES CAUSE GAS EXCHANGE TROUBLES, FROM WHICH THE ALLOWABLE LIMITS FOR FRUIT COULD BE DEFINED. COX'S ORANGE SENSITIVENESS WAS HIGHER THAN THAT OF GOLDEN DELICIOUS. FRUIT RESPONSE DEPENDS ON THE ATMOSPHERIC COMPOSITION AND EXPOSURE TIME. THE DETERMINATION OF SUCCINIC ACID, ETHANOL AND ACETALDEHYDE CONTENTS SHOWED THAT FERMENTATION TOOK THE PLACE OF RESPIRATION. THE CHANGES IN MALIC ACID CONCENTRATIONS ARE NOT SPECIFIC. A RAPID EVOLUTION OF CO2 WAS THE IMMEDIATE RESPONSE OF FRUIT TO THE REMOVAL FROM CONTROLLED ATMOSPHERE.
