The Effects of Postharvest Infiltration of Calcium, Magnesium, or Strontium on Decay, Firmness, Respiration, and Ethylene Production in Apples

Year: 1987

Type: article

Abstract: ‘Delicious’ apples ( Malus domestica Borkh.) were pressure-infiltrated (68.95 kPa) above atmospheric at harvest with CaCl 2 , MgCl 2 , or SrCl 2 . After 5 months in storage at 0°C, the fruit were removed, wound-inoculated with a conidial suspension of Penicillium expansum , and kept for 7 days at 20°. Fruit then were rated for decay severity, ethylene production, respiration, firmness, and injury, and analyzed for the concentration of the appropriate cation. Calcium was the optimum cation for reducing decay, maintaining fruit firmness, and suppressing ethylene production. Cation treatments had little effect on respiration, and Mg was the only cation that caused distinctive injury to the fruit surface.
