摘要：
The pine is the conifer the most wide-spread and the most known in the Mediterranean Basin. Its great plasticity and robustness have made him a pioneer species for large-scale production and protection reforestation. The study of the germination of two pine varieties of the Taza region (Pinus halpensis and Pinus pinaster) under osmotic stress conditions was carried out in order to control better the first problem encountered during the reforestation trials of this forest species. The effect of osmotic stress on pine seed germination using polyethylene glycol (PEG 6000) at different concentrations (from 0 to 8 g / 100 ml) has shown that the Pinus halpensis variety is more drought resistant than the Pinus pinaster variety and therefore may be recommended in arid and semi-arid areas.
