Abstract
This study was carried out to determine the effect of different NaCl and Na2SO4 concentrations, including (0, 100, 200, 300, 400 and 500 mM), on germination and initial growth of Seidlitzia rosmarinus. Germination percentage, germination rate, germination index, seed vigor index, radicle length, and ...

This study was carried out to determine the effect of different NaCl and Na2SO4 concentrations, including (0, 100, 200, 300, 400 and 500 mM), on germination and initial growth of Seidlitzia rosmarinus. Germination percentage, germination rate, germination index, seed vigor index, radicle length, and plumule length were measured. Our results showed that the most of studied characters were severely inhibited at high concentration of NaCl and Na2SO4. The results revealed that the effects of the same concentrations of NaCl and Na2SO4 on radicle, plumule and plant length were significantly different, but germination percentage, germination rate, germination index and seed vigor index did not show significant differences. In general, the results indicated that Seidlitzia rosmarinus was more sensitive to Na2SO4 than NaCl and it could be considered asa chlorophyte halophyte.

Salinity is one of the increasing problems in the world which include the wide area of our country. Regardness to increment in salinity lands and shortage in desirable soils for cultivation, recognition of range plants that are salt tolerance is very important. In order to study the effect of different salinity levels on germination of Haloxylon phyllum, Seidlitzia rosmarinus, Haloxylon persicum, Pteropyrom aucheri, Zygophllum euryypterm, Sueda fruticosa, and Atriplex lentiformis species, the experiment was conducted in germination stage as a factorial experimental based on CRD with three replications. Salinity levels applied were zero (control), 100, 200, 300, 400 and 500 mM NaCl. The results showed that with increasing salinity level, germination rate and percentage of germination were decreased. This decrease was different among the studied species. There was very significant difference between levels of salinity. Among the studied species, Haloxylon aphyllum and Sueda fruticosa had the maximum and minimum percentage of germination respectively. Seidlitzia rosmarinus and Pterophyrum aucheri had the maximum and minimum of germination rate respectively. Ability of germination in different concentrations of salinity describes rate of seeds resistance. There was very diversity for germination responses of the studied species.
