Apples are one of the oldest fruits known to mankind and have been cultivated for many years. In order to investigate the effect of foliar application of amino calcium on Golden Delicious apple trees a randomized complete block design with four repetitions was conducted in the city Abadeh, Fars Province, southern Iran. Apple trees were sprayed with different concentrations (0, 2.5, 5.0, and 7.5 mg/l) of amino calcium. After spraying the trees mature fruits were harvested and stored in cold storage houses for 3 months. After this period, traits such as amount of calcium, fruit weight, fruit firmness, and decay were assessed at the horticultural laboratory of Jahrom Azad University. We found that foliar application of amino calcium delayed and decreased the amount of fruit decay during storage. Fruit firmness was highest in apples that were sprayed with 7.5 mg/l amino calcium. Moreover, fruits that were sprayed with 7.5 and 5 mg/l amino calcium had lower weight reduction compared with fruits that were sprayed with other concentrations of amino calcium. We found no significant difference between different concentrations of amino calcium with respect to calcium levels. Key words: Amino calcium, Storage, Apples, Foliar application
