    During its lifetime, and particularly before entering production, the date palm can produce several shoots at its base, up to thirty in total. In the absence of vitro plants of local varieties, these shoots remain the ideal method for regenerating plants that are consistent and faithful to the mother plant. Date growers adopt this technique in order to propagate the noble varieties of the Figuig oasis. Among them is the Aziza Bouzid cultivar, known for its difficulty in rhizogenesis. The objective of this work is to test the effect of the season and concentrations of 3-indolebutyric acid (IBA) on the rooting of shoots from this cultivar in order to identify the most favourable seasons for transplanting shoots. And the recommended IBA concentration. Three concentrations of IBA were applied: C1 (0 ppm), C2 (150 ppm) and C3 (300 ppm). The study showed that spring and summer are the most favourable seasons for transplanting suckers, with a root regeneration rate of up to 100%. The use of IBA significantly increased the regeneration rate, breaking records, particularly for the two seasons already mentioned.
