Sete aplicações de cloreto de cálcio (0,6 ou 1,2%) foram realizadas em pré-colheita de mangas `Tommy Atkins' para verificar seus efeitos sobre o teor de cálcio na polpa dos frutos e a evolução do amadurecimento. As avaliações foram realizadas na colheita e durante doze dias de armazenamento a 25oC e 60-70% UR. Os tratamentos não elevaram o teor de cálcio na polpa e não influenciaram a perda de peso, o teor de sólidos solúveis totais, a acidez total titulável e a firmeza de polpa dos frutos. Seven applications of calcium chloride (0.6 or 1.2%) were made before harvest of `Tommy Atkins' mangoes to verify the effect on calcium content in fruit pulp and the evolution of ripening. The evaluations were made at harvest and for twelve days of storage at 25oC and 60-70% RH. There was no increase of calcium content in fruit pulp. The weight loss, total soluble solids, total titratable acidity and pulp firmness were not affected by treatments
