Abstract
The native plants of each habitat are a valuable heritage that must be sustained. In this research, we focused on the seed germination of endemic species of Iran, and a number of species were selected using the seed list of National Botanical Garden. Ornamental, medicinal and endemic potentials were the basis of selecting the species. The current research was aimed to improve the germination percentage of species in order to enhance the species diversity of National Botanical Garden of Iran. A fixed pattern was considered for seed treatments including control treatment, chilling and scarification. The main treatments were scarification and chilling. Experiments were carried out as a completely randomized design with three replications. In each replication, 25 seeds of 148 populations of 135 species were studied. Overall, 23.64% of species germinated in the control treatment, 19.6% in the chilling treatment, and 8.1 % in the scarification treatment. Totally, 51.34% of all species responded to the treatments. The seed germination percentage of species belonging to the Apiaceae and Papilionaceae families was significantly increased by chilling and scarification treatments, respectively. The seed germination behavior of some plant families was determined.
