During 2 years of storage of Węgierka Zwykła (Prunus domestica L.)
plums in controlled atmosphere (CA) the degree of internal breakdown in
the fruit and the incidence of fungal diseases were determined at 2-week
intervals. It was found that both the vegetation period and the method of
storage strongly affected the conditions of the plums. The composition of
gases applied significantly limited the development of internal breakdown
and fungal diseases as compared with cold storage conditions (CS, at 0°C).
Carbon dioxide in concentrations of 3 and 5% with a 3% oxygen content
equally affected the number of infected fruits during 10 weeks of storage.
An increase in CO2 content to 15% delayed
the appearence of internal breakdown by 2 weeks and decreased the number
of plums with signs of breakdown and fungal diseases found at the last
stage of storage life.
