The change of fruit quality parameters in day-neutral strawberries cv. Diamante grown out of season

This research was conducted on the strawberry cultivar Diamante in continental parts of Croatia.. The experiment was designed as 4 replicates with 100 plants for each harvest time. The quality of strawberries cv. Diamante grown out of season (fruit where picked at three harvest times - June 27th ; September 7th ; October 28th in the early morning hours) was determined. Total soluble solids (º ; ; Brix) ranged from 5.00 to 7.03%, total acidity was from 1.05 to 1.12%, TSS/acidity ranged from 4.74 to 6.34, vitamin C ranged from 40.73 mg/100g FW to 46.68 mg/100g FW, pH were from 3.53 to 3.72, total phenols were from 276.48 to 326.76mg/L, non-flavonoids 169.50 to 260.53 mg/L, and flavonoids from 44.71 to 106.53 mg/L, respectively. In addition, total anthocyanins ranged from 15.95 to 21.70 mg/L. L values of fruits ranged from 30.24 to 41.05, chroma (C) from 25.92 to 34.13, and Hue angle (H) from 44.51 to 56.02. The data showed that cv. Diamante grown out of season is of satisfactory quality.
