Abstract
Calcium nitrate reduces peel-pitting and cuticular water permeability of 'Fortune' mandarin when applied just before or at fruit colour-brea k. Gibberellic acid (GA(3)) also reduces the percentage of affected fr uits, although with lower efficiency. However, GA(3) had no effect on cuticular water permeability. As GA(3) delays senescence and only part ially controls peel-pitting, peel senescence may not be the unique fac tor involved in this physiological disorder. With the exception of pee l resistance to puncturing, peel pitting and cuticular permeability, c alcium nitrate did not affect fruit characteristics.
