Abstract
Angelica archangelica, Tanacetum cinerariaefolium and Chelidonium majus are valuable medicinal plants for which there is no comprehensive information about their seed germination in review of literatures. With regarding of the importance of simple propagation of medicinal plants and the role of seed in production of these plants, this study was set out in order to analyzing of the effects of cold stratification (control, 2, 3 and 4 weeks) and acid gibberellic (control, 100, 150, 250, 350, 450, 500 and 1000 ppm) treatments on seed germination of these species. Treatments were arranged seperately in a Completely Randomized Design with 3 replicates. The results showed that the highest mean germination (percentage and rate) was observed in 3 and 4 weeks (40%) and 4 weeks (1.8 seeds per day) cold stratification for Angelica archangelica seeds, 3 weeks (42.67%) and 4 weeks (6.17 seeds per day) cold stratification for Tanacetum cinerariaefolium seeds, and 100 and 350 ppm (100%) and 500 ppm (5.22 seeds per day) GA3 solutions for Chelidonium majus seeds.
