Preharvest foliar applied calcium and postharvest CO2 increment improve storability of 'Nyoho' strawberries.

Strawberry cv. Nyoho receptacles were sprayed after petal fall with 150 ppm Ca chelate at the rate of 200 litres/1000 m2. The calcium solution was sprayed once a week 2 or 4 times, with Tween-20 added as a wetting agent. Controls were sprayed with water. Harvested fruits were stored at 0 deg C for 3 weeks, either in 8-15% CO2 or in air, and then transferred to 20 deg C for 2 days. After this time, fruits in the elevated CO2 storage treatment which had been treated with Ca 4 times showed higher fruit firmness and ascorbic acid content than the control fruits. In addition, berries treated with Ca 4 times showed significant reductions in water-soluble pectins and increases in hydrochloric acid-soluble pectin compared with controls. Development of grey mold was inhibited by Ca treatment or CO2 treatment alone or in combination.
