discussionDespite the complexity of Argan fruit flowering and maturationcycles, fruit harvested in April, May, June, and July are generally con-sidered by people native of the Argan forest as very unripe, unripe,half ripe, and fully ripe, respectively. Thus fruits were collected atthe beginning of each month of the considered season on the samelot of four selected trees. Argan fruit is made of a nut containing oneor two kernels, and is covered by a pulp made of mesocarp and exo-carp. The color of the fruits (exocarp) changed from green to yellow,during the period of investigation, and fruits started to fall whenfully ripe or over-ripe (Fig. 1). These changes are locally consideredas marks of Argan fruit ripening. The present study focuses on the kernel which is currently the most valuable part; this is why, uponharvest on the trees, fruits were depulped, and the nuts broken torecover the kernels.
