Yarrow (Achillea) is one of the most important species of medicinal plants that has many applications in the pharmaceutical, cosmetic and health industries. In order to investigate the effect of seed priming on the germination characteristics of degenerate seeds,, A factorial As the form of completely randomized design with 3 replications carried in the greenhouse of the Natural Resources Gene Bank of Research Institute Forests and Rangeland in 2022.. I, three yarrow species, Achillea.nobolis, A.millifolium and A.tenufolia, were artificially senesced by applying a temperature of 40 degrees Celsius and a relative humidity of 100% (for 0, 48 hours, 72 hours), seed priming at 3 levels, including hydropriming (soaking for 24 hours in distilled water), gibberellic acid, 250 and 500 ppm. The analysis of variance showed that there were main and interaction effects of species, seed priming and seed deterioration for all the traits of emergence Characteristics were significant at P≤ 1% . Comparison of the species showed , that of A. nobolis species higher values of all traits except for dry matter compare with two other species.The species of A. millifolium was ranked as second level. The highest emergence rate was obtained in non- deteriorated (hydro) seeds. Three species have high average mean values with gibberellic acid 250 ppm for all traits except the ratio of root/stem and percentage of dry matter. . The highest root length /Shoot were obtained with gibberellic acid 250 ppm, which indicates that the aged seeds inside Pots have more rooting improvement for their survival
