摘　　要：The regeneration conditions of Chamaerops humilis L. （Arecaceae）, has been threatened by a strong tegumentary inhibition of its seeds. In this study, the authors have analyzed the germination behavior of the species to plan subsequently for protection and sustainable use of this natural resource through synchronization and homogenization of germination. In this context and to optimize Chamaerops humilis seeds germination, to overcome and to remove the obstacle of tegumentary inhibition, the treatments by soaking in distilled water, manual, mechanical and chemical scarification （H2SO4）, have been applied to the seeds of Chamaerops humilis freshly harvested in the Beni Snous area （Tlemcen Mountain, Algeria）. The seeds germination without treatment （control） has been represented by a good germination capacity （72%） and a significantly longer duration of germination （46 days）. Soaking in distilled water does not seem to have a significant effect on the rate and duration of seeds germination compared to dry seeds （P 〉 0.05）. The manual scarification has clearly improved the germination capacity of these species （92%）, and a change wed has been seen in the germination duration （16 days）. However, mechanical scarification of seeds gave only low germination rate （42%）. Seeds treatment with sulfuric acid has been found to affect the rate of germination, but this effect is varied depending on the concentration of the acid. Overall, the germination percentage has changed from 77% to 92%. The optimal value of 92% corresponds to a concentration of 96%.
