The storage behaviour of the plum variety 'Bühler Frühzwetsche' was tested in modified atmospheres with simultaneous O2 reduction and CO2 increase or CO2 increase alone. After 4 weeks in CA-store with 12% CO2 and 2% O2 at 1°C the plums showed a good appearance and a satisfying fruit firmness without any disadvantageous taste or damages. In CA conditions with higher O2 and lower CO2 or in atmosphere which was only enriched with CO2 (12%, 18%, 24%), the delay of ripening was more ineffective and the plums get riper than in 12% CO2 and 2% O2. Although plums are generally considered as a CO2 sensitive fruit, plums of 'Bühler Frühzwetsche' didn't show any CO2 damage till 16% CO2. But in higher concentrations the fruits increasingly showed cracked tips.
