Abstract

Oriental beech is one of the most important tree species in the Caspian region that regener- ates naturally. Seed pretreatment plays an important role in beech reforestation .For this reason the seeds of three different provenances; Gilan (Asalem), Nowshahr (Makarood), Gorgan (Cheshmeh gholgholy), across the Caspian region, were collected and after viability test (TTC) placed under cold stratification (for 8-19 weeks) to overcome dormancy. The results have shown that pregermination treatments had desirable effects on seed germination. There were significant variations between three origins and different treatment duration and germination characterstics. The Nowshahr and Gilan origins showed more similarity.
