The Effect of Harvest Date and Storage Conditions on the Quality of Remontant Strawberry Cultivars Grown in a Gutter System under Covers

The storage characteristics of three remontant strawberry cultivars San Andreas (R), Albion (R) and Murano (R) were studied in 2018-2020. The short-term storage conditions (7 days) of strawberries used in the study significantly affected fruit quality indicators. The highest quality of stored strawberries was provided by controlled atmosphere (CA) conditions, as evidenced by the typically highest fruit firmness and the lowest natural loss of strawberry weight. The modified atmosphere packaging (MAP) conditions obtained in the Xtend (R) bags provided a similar good storage effect for strawberries. Strawberries stored in MAP bags had the lowest respiratory intensity, and their firmness and the percentage of rotten fruit were the same as those stored in a controlled atmosphere. In addition, MAP bags were effective in reducing the weight loss of stored strawberries. The quality of strawberries stored in a conventional air storage (AA) was slightly lower compared to the fruit stored in a controlled and modified atmosphere. This was due to their lower firmness and significantly higher respiration intensity and higher weight loss. In addition, the percentage of rotten fruit, although low, has always been the highest among AA strawberries. The quality of the strawberries also depended on the date of fruit harvest. Strawberries harvested later, compared to those collected earlier, were generally characterized by higher firmness, lower acidity and lower respiration intensity.
