Abstract
Abstract From 1981-83, 4 weekly sprays of 0.75% and 1% CaCl 2 w/v, immediately prior to harvest, significantly increased fruit flesh Ca concentration of ‘Golden Delicious’ apple ( Malus domestica Borkh.) without the leaf phytotoxicity associated with CaCl 2 sprays above 1%. In contrast, chelated Ca sprays at concentrations 2 – to 16 × label recommendations, and direct trunk injection of 1.5 liters of 1% CaCl 2 , did not increase fruit Ca concentration.
