The effect of boron and vitamin C foliar application on the yield and quality of strawberry fruit

Strawberry is a very tasty fruit with high nutritional value, so it is important to increase the size of the fruit and its quality. The aim of this study was to investigate the effect of boron and vitamin C on the yield and quality of strawberry fruit. The research was carried out as a completely randomized design experiment with ۹ treatments and ۴ replications at the beginning of flowering. The treatments include boron (۵۰ and ۱۰۰ mg/L) and vitamin C (۱۵۰ and ۳۰۰ mg/L) and their combination. Traits such as leaf area, chlorophyll index, weight of primary fruit, weight of secondary fruit, number of achenes of primary fruit, number of hazelnuts of secondary fruit, yield, soluble solids, pH, organic acids and vitamin C were investigated. The results showed that the use of different concentrations of boron and vitamin C and the combination of these two causes the improvement of leaf surface, chlorophyll index, primary fruit weight, secondary fruit weight, primary fruit hazelnut number, secondary fruit hazelnut number, yield, soluble solids, pH, organic acids and vitamin C of strawberry fruit. Combination treatments of ۱۰۰ mg/L of boron and ۳۰۰ mg/L of vitamin C and combination treatment of ۱۰۰ mg/L of boron and ۱۵۰ mg/L of vitamin C, combination of ۵۰ mg/L of boron and ۳۰۰ mg/L of vitamin C, and combination treatment of ۵۰ mg/L of boron and ۱۵۰ mg/L of vitamin C showed better results in the examined traits. According to the results obtained from the present research, the combination of boron and vitamin C improved the quantitative and qualitative characteristics of strawberry fruit better than their use alone.
