  ABSTRACT
  The Pistacia atlantica Desf. (Anacardiaceae) is widespread in North Africa, it is found in the Dayas, its extreme areas, in the form of sparse stands. It is a species that can constitute interesting populations in arid and semi-arid zones, hence the interest of studying the effect of provenances (25 regions of Algeria) on germination and seed emergence. In this context, 120 seeds were tested in the laboratory to know the effect of provenances on germination, the same procedure was used to know the effect of provenances on emergence (in the nursery). The seeds were divided into lots of 20 seeds (the number of replicates is 6 to reach the degree of freedom “DDL”). The results obtained show that the germination rate seems to be better for the provenances of Saida, Naama and EL Bayadh (≥ 90% for 45 days). On the other hand, the provenances of Relizane, Tlemcen, Guelema, Oued, Biskra, Ghardaia, Mascara, Bouira, Djelfa, Sidi Bel Abbes and Mesila give only very poor results (≤ 20%), while the other provenances give a medium result (≈ 50%). Regarding emergence, the provenances of Laghouat, Saida, Tiaret, Bechar, Naama and Batna give a good result (≥ 90%) while the result is very low for the provenances of Adrar, Biskra, Oued, Ghardaia, Mascara, Bouira, Relizane, Sidi Bel Abbes and Djelfa. In view of these results, the use of Pistacia atlantica in the restructuring of degraded arid spaces constitutes an interesting option and provides some answers to foresters in terms of the choice of provenance likely to be used in reforestation programs.
