The effects of calcium (Ca) application on fruit firmness, ethylene concentration and Ca uptake of ‘Jonagold’ apple [Malus sylvestris (L.) Mill. var.domestica (Borkh.) Mansf.] were investigated. A 2.5 g⋅L-1Ca (1.425g⋅L-1calcium sulphate dihydrate, 0.675g⋅L-1calcium chloride and 0.4 g⋅L-1others) solution was applied to whole tree at 4 days intervals from 20 to 60 days after full bloom (DAFB) . Ca treatment decreased internal ethylene concentration compared to the untreated control. Bound Ca concentration in the cell wall of Ca-treated fruit was higher than that of untreated control. Although the firmness of Ca-treated fruit showed higher value than that of the control before coloring, they had no significant difference after coloring. These results demonstrate that Ca treatment at 20-60 DAFB may prevent the increase of ethylene production, resulting in the delay of fruit senescence, prior to coloring, which is often observed in warm regions.
