Current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mM) of different salts including NaCl and Na2SO4 on germination and initial growth phase of Halostachys caspica were studied. The experimental design was completely randomized design with three replications. Characters of percentage, speed and index of germination, seed healthy index, radicle, plumule and plant length were measured. For analyzing of results were used of ANOVA, Duncan test and parried T– test sample in SPSS software. It was compared with germination under control condition, the most of characters of NaCl salt were not affected by 100 mM NaCl but were affected significantly different by 100 mM Na2SO4 salt. The results showed that effect of same concentration NaCl and Na2SO4 on radicle, plumule and plant length are significantly different but on percentage, speed and index of germination and seed healthy index the different aren’t significantly. The results showed that germination percentage were severely inhibited by 500 mM NaCl but no affected severely by 500 mM Na2SO4. However, the results showed that Halostachys caspica in growth characters such as, radicle, plumule and plant length is more sensitive to Na2SO4 than NaCl salt but in germination characters such as percentage, peed and index of germination is more sensitive to NaCl than Na2SO4 salt. At least we can put Halostachys caspica chloridephyte and sulfatephyte group of halophytes.

Halophytes, as integral parts of many marine, coastal and terrestrial ecosystems, can play an important future role for biosaline agriculture, forage production and habitat restoration. There is currently a lack of public awareness and scientific documentation regarding nutritive value of halophytes. The aim of this research was to determine nutritive value of native halophytes of Iran. Seven saline indicator species of Iran including Halocnemum strobilaceum, Halostachys caspica, Seidlitzia rosmarinus, Salicornia herbacea, Alhagi persarum, Salsola regida and Atriplex leucoclada were sampled at three phenological stages (vegetative, flowering and seed ripening). Then, the plants were powdered and six quality traits, Crude Protein (CP), Acid detergent fiber (ADF), Moisture, Metabolizable Energy (ME), Ash and Dry mater digestibility (DMD) were determined. ANOVA results revealed that there were significant differences among all species and phenological stages. ME, DMD and CP decreased in all the species in three stages, but ADF changed significantly in seed ripening stages in H. strabilaceum (20.63), S. rosmarinus (17.61 %) and H. caspica (17.4 %). The difference was not significant in flowering (32.56%) and seed ripening (31.66 %) stages for A. persarum. Increasing of ash and moisture content in flowering stage in succulent halophytes helps them to tolerate salinity. Due to less fiber and more CP, ME and DMD, S. regida has the highest nutritive value and A. leucoclada has the lowest value. Also, late vegetative or early flowering stages are the best time of forage quality according to these traits.
