e0“Fruit of ‘Golden Delicious’ apple ( Malus domestica Borkh.) infiltrated after harvest with CaCl 2 solutions of up to 12% (w/v) had lower ethylene production rates than untreated fruit during a 7-day period at 20°C immediately following treatment”
e2“High calcium concentrations resulted in a decrease in the magnitude of ethylene production but had no effect on respiration”

Other claims from this paper (7)
- Intervention effect Calcium chloride infiltration lowered ethylene production rates of apple fruit relative to untreated fruit over a 7-day period at 20°C.
- Intervention effect After 5 months of storage at 0°, the effect of calcium on ethylene production diminished rapidly during a 7-day ripening period.
- Intervention effect Calcium treatment had no significant effect on fruit respiration rate.
- Intervention effect Calcium treatment left titratable acidity and percentage of soluble solids unaffected, even at high concentrations.
- Association Fruit firmness was positively correlated with fruit calcium concentration both before and after storage at 0°.
- Association Ethylene production over the 7 days after calcium treatment was negatively correlated with fruit calcium concentration.
- Association Soluble polyuronide content of apple fruit was negatively correlated with fruit calcium.
