Abstract :

The species of Alhagi camelorum is a family of Papilionaceae and legumes. A.camelorum is important and dominant in saline areas of Golestan province which is important for forage production, soil conservation and medicinal value. In nature, the seed germination percentage for this species is low. The purpose of this study was to investigate the effect of different treatments of sulfuric acid, boiling water, scrub, and control on the failure seed dormancy and seed germination. Seeds of this species were collected from its natural habitat in Aq-qala, Golestan province. The effects of different treatments of sulfuric acid (15 min, 20 min, 25 min), 100-degree boiling (2 minutes and 4 minutes), scrubbing and control were investigated with 4 replications. The results of this study indicated that sulfuric acid had the most effect on germination (15 min) (89%). Other treatments were 25% Sulfuric Acid with 86%, Sulfuric Acid for 20 minutes with 75%, 2 min with 67%, 4 minutes with 36%, 20% and 6% for germination. Also, the results of this study indicated that the most suitable planting depth for this species is 2 cm. In all measured parameters, the lowest amount was obtained in the control treatment.
