Abstract
This research was done in order to investigate the seed age effects (longevity) on germination of some sagebrush of species. East Azerbaijan was chosen as the collection sites and seeds of four species such as Artemisia fragrans, A. spicigera, A. campestris and A. vulgaris were collected from these sites. Seed germination of these species was tested in the spring of the three following years and the data analyzed statistically. Results showed that seed ages have positive effects on the viability and germination of all species under study.. Minimum and maximum changes in seed germination belonged to Artemisia vulgaris and Artemisia spicigera respectively.
