Abstract:
Strawberries are one of the major fresh market commodities produced in Florida, with a harvested area of approximately 10,000 acres. The objectives of this research were to compare genotypes for color, shriveling severity and decay severity before and after storage. Genotypes were compared to determine the response to storage at 4°C and 95% RH for weight loss, soluble solids, total sugars, titratable acidity, total ascorbic acid, anthocyanins and phenolics contents across multiple harvest dates during the 2011-12 and 2012-13 seasons. Subjective quality measures and weight loss of each of fifteen individual strawberries were evaluated using rating scales (1-5). Significant differences were noted among genotypes for weight loss and quality measures after storage. ‘Strawberry Festival’ and selection FL 09-127 obtained stable weight loss after storage; these genotypes also showed consistent color ratings nearest to 3 and displayed acceptable levels of shriveling and decay severity during both seasons relative to other genotypes. Chemical traits were highly influenced by genotypes, seasons, harvest dates within seasons and cold storage. Selection FL 09-127 has shown constantly high values of soluble solids (7.2-8.2%) and total sugars (5.2-10.6 g/100g) contents after storage. High values of total ascorbic acid (230-603 mg AA/100g) and phenolic contents (2448-2840 mg gallic acid/100g) after storage were observed in selection FL 07-193; however its total anthocyanin levels were usually lower compared to other genotypes. In contrast, FL 10-47 has shown lower total ascorbic acid values but consistently high total anthocyanin (89-321 mg PGN/100g) and total phenolic (1018-2759 mg gallic acid/100g) contents.
