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.

This research was performed to determine the nutritional value of a halophyte species, Halostachys caspica in three different phonological stages including primary growth, flowering and seed ripening in three different sites i.e, Qom, Yazd and Urmia provinces Plant sampling was completely randomized and crude protein, ether extract, water percentage, acid detergent fiber, ash, dry matter digestibility and metabolism energy were measured by standard methods. Data analysis was done using SPSS software in a factorial design. According to the results, interaction effects of growth stages and different ecological sites showed a significant difference for most of the measured factors and they did not follow a regular trend. The results indicated that H. caspica had the highest forage quality in flowering (second stage) while with increase of plant age, crude fiber and ash increased in all the three studied sites. Growing in sever ecological conditions and having high forage quality, H. caspica may be considered for sustainable development plan in saline regions.
