The relationship between internal breakdown in mango fruit and fruit mineral element concentrations and fresh weight was investigated. Fruit were collected weekly from a commercial orchard beginning 4 weeks after fruit set (WAFS) until the fruit were ripe. The concentrations of nitrogen (N), phosphorus (P), potassium (K), Ca, magnesium (Mg), zinc (Zn), copper (Cu), manganese (Mn), iron (Fe), and boron (B) and fresh weight of "Tornmy Atkins' mango fruit with and without interna I breakdown were compared. Disordered fruit weighed more than healthy fruit 4 WAFS. However, when fruit were ripe there were no significant differences in fruit weight between healthy and disordered fruit. Disordered fruit contained significantly higher concentrations ofN, P, Ca, and B than the healthy mango fruit, 4 WAFS. When fruit were ripe, there were no differences in N, K, Ca, Mg, Zn, Mn, Fe, and B concentrations between healthy and disordered fruit. Ripe, healthy fruit had higher Cu and lower P concentrations than ripe, disordered fruit. Internal breakdown could not be specifically Iinked to a Ca deficiency in mango fruit at any stage of fruit ontogeny.  amangoes  aweight  aCálcio  aDeficiência  aManga  aMangifera Indica  aPeso  aCalcium deficiency  aConcentracao mineral  aDesordem fisiologica  aMineral concentration  aPhysiological disorders1 aSCHAFFER, B.1 aBRECHT, J.
