The influence of ethylene contamination on quality attributes, brown rot (Monilinia fructicola) decay development and internal breakdown during longterm cold storage at 0 and 5 0C was investigated on climacteric and non-cli-macteric stone fruits. Quality attributes such as fruit flesh firmness, soluble solids concentration, titratable acidity, stem browning, and flesh and ground color were not affected by constant ethylene exposure (10 ppb and 1,000 ppb) during long-term cold storage at 0 and 5 0C. Constant ethylene exposure did not affect decay development, expressed as lesion size and incidence, on peaches, plums, nectarines and cherries wound-inoculated with Monilinia fructicola during long-term cold storage. In peaches, ethylene treatments did not affect development of visual mealiness symptoms. In one case, flesh mealiness symptoms were delayed by ethylene present during storage. This work indicates that there is no commercial benefit to remove ethylene during cold storage for peaches, nectarines, plums and cherries.
