Scarification is one of the most effective treatments in improving seed germination. The seed germination percentage of some species is increased by scarification treatment. In the current study, the seeds were collected from different regions of the country and the effects of scarification on seed germination percentage and germination speed of Hedysarum formosum, Sesbania punicea, Vicia lathyroides, Ononis spinosa from Papilionaceae family, Althea wilhelminae from Malvaceae family, Bryonia aspera from Cucurbitaceae family,and Vaccaria grandiflora from Caryophyllaceae family were studied. According to the obtained results, scarification had a significant positive effect on seed germination percentage and germination speed of all species except Bryonia aspera. However, scarification treatment had no significant effect on seed germination percentage of Hedysarum formosum, but increased the speed of seed germination. Our results clearly showed that scarification could enhance the speed of germination in the species of papilionaceae family, as compared to other families.

Nowadays, with regard to the global view of desert issue and necessity of using adaptable species in combat desertification, it is urgent to identify and remove the constraints of their production and establishment. Ammodendron persicum is one of the important and compatible species in desert ecosystems. The current research was carried out to investigate the effect of different treatments on seed dormancy breaking and germinationstimulation ofAmmodendron persicum in order to determine the most effective treatment in enhancing of germination and primary growth of seedlings .The experiment was done in a Randomize Complete Block Design (RCBD) with 8 treatments and 4 replications. Different treatments were applied including scarification plus sulphuric acid (H2SO4 98%) for 10 and 15 minutes, scarification with sandy paper, scarification plus putting the seeds in hot water for 10 and 15 minutes, KNO3 (0.1 and 0.2 %), a complex treatment of scarification and KNO3 (0.1 and 0.2%) and distilled water as control treatment .To analyze the data, ANOVA was used and Duncan test was applied to compare the means. The result showed that scarification with sandy paper had the highest effect onseed dormancy breaking and seed germination stimulation of A. persicum as germination percentage increased from 3% in distilled water to 68% in scarification treatment.
