Abstract
On the coast of Hormozgan province, there are halophytic grasses distributed in coastal plain, near to the coastline. They are potential forage crops which could be used to reclamation of coastal sandy saline soil deserts. The aim of this study is introducing of suitable methods for seedling production of Halopyrom mucronatum, Aeluropus lagopoides and Sporobolus arabicus as native grasses of coastal sand masses in the eastern part of Hormozgan Province, Iran. The geographical distribution of Halo. mucronatum, Ael.lagopoides and Spo.arabicus was obtained by the help of literature review. In next stage with Referring to the field and collecting stolons and seeds of these species, seedlings were produced from cutting stolons and seeds. After planting, the percentage of produced seedlings was recorded. Using appropriate statistical tests, the best way of reproduction for each of the selected species was introduced. Test treatments were include of soaking in boiling water, soaking in acid gibberellic (1000 ppm) and stolones cuttings. Based on the results, the highest percentage growth of all three species was cutting treatment (91.6%) and the lowest percentage growth were in the control (7.9%) and treatment of gibberellic acid on seeds (0%). So that in the acid gibberellic treatment, no growth was observed. Of the three species, propagation of Spo. arabicus was more successful by stolon (100%) and seed or control method (52.4%). Based on these results, it seems that the best method for producing seedlings of these species is using stolon cuttings with 81 to 100% success.
