The effectiveness of CaCl2 and short period of hypobaric (LP) treatment, alone or in combination, to increase storage life of strawberry fruits, was investigated. In single treatment, CaCl2 was applied by postharvest dipping at concentrations of 0 (control), 0.25, 0.5, and 0.75 mM; hypobaric (LP) treatments at 0.4 and 0.8 atmosphere were applied for 2 h. Untreated strawberry kept at normal pressure (near 1.00 atmospheres) was used as controls. Fruit quality and decay incidence was evaluated after 14 days storage at 1°C, followed by 24 h at 20°C. CaCl2 and Hypobaric treatments applied alone significantly reduced fruit decay after 14 days storage at 1°C. Percentage of marketable fruits, fruit firmness, total soluble solid and vitamin C was superior in fruits treated by CaCl2 or short period hypobaric treatments after 14 days storage. A combined treatment with 0.75 µM CaCl2 and 0.8 atm was the best in controlling fruits decay and enhancing quality of fruits during storage. The results indicated that the combination of hypobaric and CaCl2 treatment is a valid strategy for increasing the effectiveness of the treatment in controlling postharvest decay and improving strawberry fruit quality during storage.
