Effect of Different Spring Planting Periods on Pomological and Phytochemical Characteristics of Some Strawberry Varieties

The study was carried out at Bilecik Seyh Edebali University Agricultural Application and Research Center during the period of 2020-2021. Its objective was to assess the influence of different planting dates (27 March, 10 April, 27 April, 15 May) on the pomological and phytochemical attributes of diverse strawberry cultivars (Albion, Pineberry, Monterey, and Portola). The goal was to determine the optimal spring planting periods and varieties that are well-suited for the region. The Monterey and Albion varieties achieved the highest average fruit weight during the third period, with weights of 14.76 g and 15.92 g, respectively. The Monterey variety exhibited the greatest pH level at 3.88, whilst the Pineberry had the lowest pH level at 3.67. The concentration of soluble solids ranged from 4.73% to 8.56% among the different varieties, and from 5.82% to 6.15% throughout the different planting periods. The Monterey variety exhibited the highest anthocyanin concentration (117.73 μg Plg-3-glu g-1 dw) among the various strawberry varieties, while the fourth planting period showed the highest content (84.65 μg Plg-3-glu g-1 dw) among the different times.
