Résumé

The changes of firmness and weight were monitored for apples over a 2-year experiment. The firmness of apples, indicated by the stiffness factor, showed a decline following storage. An exponential or a second order polynomial regression model was found to fit the experimental firmness data. A linear regression model appeared able to express the weight loss of marketable apple fruits. Parameters of the models should be adjusted based on the initial conditions of the fruit and the storage conditions in postharvest practice.
