The objective of this study was to investigate effects of foliar calcium application on storage of sweet cherry. Different concentrations of CaCl2 (2.4, 3.2, and 4.0 g/l) and Ca(NO3)(2) (3.4, 4.6, and 5.8 g/l) were applied six times by foliar spraying on leaves and fruits of the sweet cherry variety '0900 Ziraat'. Harvested fruits were packaged in 500 g plastic boxes and stored for four weeks at 0 C-0 and 90-95 % relative humidity. During the experiment, flesh firmness, titratable acidity value (TA), pH, total soluble solids content (SSC) ratio, and weight losses were weekly assessed. The results indicated that there were positive effects of foliar calcium applications on fruit quality coupled with improved firmness, and enhancement of TA, an additional advantage for consumer acceptability.
