Effect of foliar application with calcium silicate on calcium amount, total antioxidant content and some qualitative and quantitative characteristics of two strawberry cultivars
Increasing of visual quality and nutraceutical properties of fruits plays an important role in fruit marketability and economic incomes of gardeners. Silicon and calcium can play an important role in fruits quality improvement. This study was conducted to evaluate the effect of foliar application with calcium silicate (0, 50, 100 and 200 mg/L) on some fruit quantitative and qualitative characteristics, total antioxidant and calcium content of two strawberry cultivars (‘Camarosa’ and ‘Selva’). The experiment was performed in a factorial based on randomized complete block design with 5 replications. Results showed that fruit length, fruit length to width ratio, fruit fresh and dry weight, vitamin C content in ‘Camarosa’ fruits were more than ‘Selva’ fruits, whereas fruit firmness, TA, TSS, total phenolic, antioxidant content, amount of calcium and catalase enzyme activity of ‘Selva’ fruits were significantly more than the ‘Camarosa’. With application of calcium silicate, fruit length, fruit fresh and dry weight, fruit firmness, the amount of vitamin C, TA, TSS, total phenolic, antioxidant, calcium content and catalase enzyme activity were increased. According to the results, foliar application of calcium silicate at 200 mg/L had the highest effect on improvement of quantitative and qualitative traits of strawberry fruits.
