The role of foliar applications of boron and gibberellic acid (GA3) on yield and quality in different strawberry types

This study was carried out to investigate the effects of boric acid and gibberellic acid (GA3) applications on yield and quality in strawberry cultivars. In the experiment, 5 different doses of boric acid (Control, 100, 200, 300, 400 and 500 ppm) and GA3 (Control, 20, 40, 60, 80 and 100 ppm) were applied. As a result of the applications, the average number of flowers was determined between 29.9-50.7. Fruit weights in the experiment varied between 17.1-22.3 g. Brix value varied between 6.3-7.9%. The pH values of the fruits were found between 2.5-2.9. Titratable acidity value was measured between 0.5-1.1 %. It was determined that the applications made a difference in terms of yield and quality in strawberry cultivars. As a result: for Sabrina and Albion cultivars, doses of 200-400 ppm are recommended, which positively affects the yield in boric acid application. However, taking GA3 applications into consideration shows a wide variation between cultivars and applications.
