Seeds of forty species of medicinal plants produced in the Medicinal Plant Garden of the Faculty of Agriculture; Ferdowsi University of Mashhad, Iran were obtained to assess their germination. Germination tests were performed in H2O and then dormancy breaking treatments (removing mucilage and seed coat, scarification, pre-chilling, GA3 and KNO3) applied on the species which showed germination below 70% in H2O. Seeds of 17 species (i.e. Linum usitatissamum and Amaranthus annus) had high germination (over 70%) in H2O. Dormancy breaking treatments were effective on 13 species (i.e. Ocimum basalicum and Echinacea purpurea) out of 23 species.
