| Abstract:
‘Manila’ mango is one of the most important cultivars grown in Mexico. Fruit harvest maturity is based on several practical indices among which water volume removed by the fruit is a precise method. So in a study carried out using sixteen 31 year-old mango tres from a grove located at the Cotaxtla Experimental Station, in Veracruz, Mexico 11 samplings of fruits per sample and each tree, were done starting at 20 days of age up to 131 days (30 days after maturity). Fruits sampled were divided by their basal, medium and distal diameters in height and width; as well as length from the base of fruit to the middle and from this to the distal end. Results indicate that an equation could be generated which estimate, fruit volume at any growth stage. Such an estimated volume is not statistically different from the fruit volume determined by the usual water displacement method. It was also determined that fruit growth is based on a polydimensional manner and it is isometric. Fruit shape is semielliptic and its growth follows a single sigmoid curve. | |
