The paper presents the influence of storage conditions on two varieties of plums: 'Stanley’ and 'Bluefree’. In order to assess the influence of different factors, several indicators were taken into consideration: physiological parameters, quality indicators and bioactive compounds variations. Both 'Stanley’ and 'Bluefree’ plums varieties were harvested at the end of August 2021 from an organic orchard located in Prahova County and stored in three different conditions: 1) normal atmosphere (NA) with 1°C and 95% relative humidity (RH), 2) controlled atmosphere (CA) conditions with 1°C, 95% RH, 3% O2 and 5% CO2, and 3) CA conditions with 1°C, 95% RH, 1.5% O2, and 10% CO2. The samples were evaluated in seven different moments: initially (at harvest), after 2, 4, 6, 8, 10, and 12 weeks of storage. For both 'Stanley’ and 'Bluefree’ varieties, the storage period was shorter in NA than for those stored in CA conditions (2 weeks shorter for 'Stanley’ variety and 3 weeks shorter for 'Bluefree’ samples). The results showed that total titratable acidity and dry matter content registered similar variation trend during storage period for both samples, stored in all conditions. The obtained results suggest that the plums stored in controlled atmosphere conditions, kept their qualities better and for longer than those stored in NA.
