【 摘 要 】

‘Regina’ sweet cherry fruit (Prunus avium L.) harvested from trees grown on vigorous and semi-dwarfing rootstocks was stored in normal atmosphere (NA) at 8°C and 2°C, and in a controlled atmosphere (CA) 3% O2 + 5% CO2 at 2°C for two weeks. At harvest time, the fruits differed in the measured quality parameters (firmness, soluble solids content - SSC, titratable acidity - TA) depending on the rootstock. The storage conditions and the rootstocks significantly influenced the fruit quality parameters after storage. Generally, reduced fruit firmness and TA, and higher SSC and SSC/TA ratio were observed at the end of the storage period. Among the rootstocks, the lowest soluble solids content was found in the fruit from trees on the vigorous F12/1 rootstock. The lower storage temperature decreased the SSC independently of the storage atmosphere composition. Firmer fruit was found in CA 2°C compared with the other two treatments. The greatest loss of weight was found after fruit storage in NA 8°C. The extent of fruit decay depended on the season, storage conditions and the rootstock. Storage in NA 8°C of the fruit grown on F12/1 rootstock resulted in the highest percentage of fungal decay. The best retention of the green colour of the peduncle was noted in CA 2°C. The findings on how the rootstocks affect sweet cherry fruit properties can be useful for sweet cherry breeding programmes, as well as for sweet cherry crop production and storage technologies.
