Changes in elastic and plastic components of mango (Mangifera indica L. cv 'Cogshall') fruit growth were analyzed with a model over time response to various assimilate supplies. The is based on water relations (water potential osmotic turgor pressures) at the level. Variation was modeled as function modulus variation pressure. using Lockhart (1965) equation. In this model, parameters (yield threshold pressure cell wall extensibility) varied during growth. Outputs diurnal seasonal growth, These variables simulated good accuracy by particularly observed increase size increasing availability supply. Shrinkage sensitive surface conductance peel, elasticity hydraulic conductivity fruit, whereas rate highly linked changes extensibility yield pressure, regardless According generally zero day shrinkage swelling behavior fruit. During night, growths positive, resulting expansion.
