Abstract : Eleven fruits from each of sixteen 31-year-old mango trees from a grove located at the Cotaxtla Experimental Station, Veracruz, Mexico, were sampled from 20 days up to 131 days old (30 days after maturity). The basal, medium and distal diameters in height and width, the length from the base of fruits to the middle, and that from the middle to the distal end, were measured. An equation was formulated which could estimate fruit volume at any growth stage. The estimated volumes were not statistically different from the fruit volume determined by the usual water displacement method. It was determined that fruit growth was polydimensional and isometric. Fruit shape was semielliptic, and growth followed a single sigmoid curve.
