Comparative Study of Four Argania spinosa L. Skeels Provenances from Morocco and Tunisia

The present work was carried out in the laboratory and at the experimental station of the Oujda Faculty of Science, where we undertook a cultivation trial of two provenances of Argania spinosa from Morocco and Tunisia to see their germination and growth behavior. After one month's germination of Argania spinosa seeds in the laboratory, the germination rates of seeds from Foum El Hassen and Miouzour were the highest compared with seeds from the Faculté des Sciences d'Oujda and the Béni-Snassen region. In fact, seeds from Tunisia had an advantage over those from Morocco in terms of germination capacity. Monitoring growth over time showed no significant differences between seedlings of Tunisian and Moroccan origin. The growth in height of four provenances showed a similarity in the general growth pattern.
