ABSTRACT :
Multi-year trials were conducted to assess the effects of controlled atmosphere (CA) storage with varying CO2 concn on the incidence of rots (especially Monilinia spp.) and internal breakdown (IB) in fruits of the plum cultivars Stanley, President and Angeleno and the nectarine cultivars Stark Redgold and Caldesi 2020. Stanley and President fruits were stored for 60 d (intermediate monitoring at 20 and 40 d), Angeleno fruits were stored for 90 d (intermediate monitoring at 30 and 60 d), and Stark Redgold and Caldesi 2020 fruits were stored for 40 d (intermediate monitoring at 20 d). The CO2 rates in CA storage, at 0 deg C and 92-95% RH, were 2.5, 5, 10, 15 and 20% for plums and 2.5, 5 and 10% for nectarines; O2 concn was 1.5-2%. Fruits in both CA and regular air storage at 0 deg C (control) were assessed after holding for 2-3 d at 20 deg C. Stanley fruits showed reduced incidence of IB and rot at 10% CO2 while higher concentrations proved phytotoxic after 40 and 60 d storage. President fruits sh
owed reduced IB incidence and severity at 15 and 20% CO2 without toxicity even after 60 d storage, whereas CO2 concn >2.5% induced marked rot in Angeleno fruits. At 5 and 10% CO2, Stark Redgold fruits showed diminished IB and rots, the latter concn proving the most effective. The incidence of IB and rot in Caldesi 2020 fruits were similar in CA and regular storage.
