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.

Flooding is one of the most important environmental stresses that affect the performance of plants. The effects of flooding height on the performance of the two species A.littoralis, J.maritimus were studied. This experiment was carried out the factorial experiment in a completely randomized design with 4 treatments and 8 replications. After 2.5 months of ultimate recovery tests were performed. The number and length of stolons of A. littoralis were counted separately in each treatment. The number and length of rhizome J. maritimus species in each plot (pot) were counted. The total weights of dry matter, shoot dry weight, dry weight of underground organs were measured in each experimental unit. Analysis of variance showed that the effects in controlling the height of flooding on all performance indicators studied (excluding the effects of flooding on root dry weight) of two species A. littoralis and J. maritimus is significant. Comparison of performance indicators A. littoralis species show between the two treatment groups (7 cm below the water level and water treatment) and treatment (treatment without irrigation and 15 cm below the water level) there is a significant difference. Comparison of performance indicators J. maritimus species show a significant difference in the number of rhizome, total length of underground rhizome and dry weight were observed. Comparison of dry pasture species show the highest production of the two types of treatment 7 cm below the water level.
