Abstract
Taverniera cuneifolia is one of the most important palatable rangeland species in Hormozgan province that unprincipled and excessive exploitation has destroyed the natural habitats of this valuable species. Only careful planning and crop cultivation and observing the rotation frequency and promoting plant cultivation in the habitat can be an effective step to maintain the survival of this species. In this study, Taverniera seeds were collected from two habitats (Geno and Tezerj) and pre-emergence treatments were soaking in sulfuric acid for 15 minutes, soaking in sulfuric acid for 30 minutes, soaking in warm water (70 °C) for one hour, soaking in gibberellic acid solution at a concentration of 1000 mg/l for 24 hours, scarification with sand, soaking in a potassium nitrate solution at a concentration of 0.1 molar for 24 hours, soaking in normal water for 24 hours and control. According to the results, all treatments had a higher germination percentage than the control. Meanwhile, treatments placed in sulfuric acid for 15 and 30 minutes caused 100% seed germination and were superior to other treatments. Sulfuric acid treatment for 15 minutes had the highest germination rate, and sulfuric acid treatment for 30 minutes had the highest radicle and plumule length.
