During fruiting of 'Tommy Atkins' mango trees, foliar sprays of calcium chloride (0.6 and 1.2%) were applied seven times at 2-week intervals. Fruits were harvested in two dates: 16/12/96 (normal harvest) and 06/01/97 (late harvest). There was no increase of calcium content in the mesocarp of the fruits of treated trees as compared to untreated controls. The physiological disorder (internal breakdown) incidence was similar between treatments independently of N or Ca contents in the mesocarp of the fruit. This disorder increased for late harvest in all treatments.
