Effect of glutamic acid on some quantitative and qualitative attributes of strawberry ‎fruit (Fragaria× ananassa, cv. Albion) under hydroponic conditions

Today, due to the importance of producing organic products and increasing demand, the use of healthy and organic compounds such as amino acids (glutamic acid) to increase the quality and quantity of the product, is very important. In this study, the effect of glutamic acid at three levels (0, 200 and 300 mg / l) as a foliar application on some quantitative and qualitative characteristics of strawberry cultivar Albion under hydroponic conditions was investigated. According to the results, effect of glutamic acid on plant height, fruit shape, total yield, fruit flavor, titratable acidity, firmness, total anthocyanin and vitamin C of fruit tissue was significant. The highest total yield, soluble solids, tissue firmness, total anthocyanin and vitamin C of fruit tissue was observed in glutamic acid treatment with a concentration of 300 mg / l. Also, the highest titratable acidity was recorded in the control treatment. According to this study, the use of glutamic acid at a concentration of 300 mg / l is recommended to improve the quantitative and qualitative properties of strawberry fruit, but requires further research.
