In order to investigate the effect of foliar application of chelated calcium on Red Delicious apple trees, a randomized complete block design with four repetitions was conducted in the city Abadeh, Fars Province, southern Iran. In this experiment, different concentrations (zero, 2.5, 5.0, and 7.5 mg/l) of calcium chelate were sprayed on the apple trees. After spraying the trees, mature fruits were harvested and kept in the cold house for 3 months. After this period, traits such as TSS percentage, fruit weight, fruit firmness and decay of tissue were assessed at the horticultural laboratory of Jahrom Azad University. The results showed that the percentage of fruit decay in the control treatment was more than the other treatments. The foliar application of calcium chelate on apple trees considerably reduced fruit decay during storage. The highest fruit firmness was related to apples that were sprayed with chelated calcium at concentrations of 0.5 and 7.5 mg/l. Moreover, the fruits sprayed with the control treatment had the highest percentage of weight loss. Spraying fruit trees with chelated calcium led to less weight loss during storage. The highest TSS percentage was related to apples treated with 7.5 mg/l chelated calcium. Keywords: chelated calcium. Spray. Strength. Durability. Red Delicious Apple.
