The effects of glycine betaine on pomology, yield and biochemical characteristics of strawberry plants under soilless culture

Glycine betaine (GB) is a quaternary ammonium compound that can be found in a wide range of bacterial, plant and animal species. Exogenous GB application is a convenient and effective approach for enhancing the stress tolerance of crops and improving crop productivity. In this research, the effect of three different GB concentrations (0, 10, 20 mM) on morpho-physiological features (crown diameter, crown number, leaf number, chlorophyll index, leaf temperature and leaf area index-LAI), pomology (fruit weight, total soluble solids-TSS, pH), yield and biochemical characteristics (total phenol-TPC, total anthocyanin-TAC, antioxidant activity-EC50) of 'Festival' strawberry cultivar under soilless culture were investigated. Results showed that 10 mM GB increased fruit weight and yield per unit area. Crown diameter, crown number and leaf temperature were positively affected by glycine betaine application. The highest crown diameter and crown number was obtained from 20 mM GB concentration while the highest yield and fruit weight were determined from 10 mM GB. In addition, the highest antioxidant activity was recorded on 10 mM GB application.
