In this research the adaptability of ten palatable species of Salsola in saline areas of East Azarbaijan province was studied. At the first step the collection of seeds was need for each species by travelling to the different areas in the province. The Perenial Species were Salsola ericoides,Salsola dendroides ,Salsola gemmascence, Salsola tomentosa and Salsola persica of which two species Salsola dendroides and Salsola gemmascence were palatable while the other three were not. Four species Salsola gemmascence,Salsola ericoides, Salsola tomentosa,Salsola persica are not the inhabitants of the major saline areas near the Uromieh Lake and their dispersion areas mainly occured on marny hills which helped to their fixation.Salsola dendroides was the only species found on the field borders,near the Uromieh Lake,where the salinity was somewhat low. This species also grows prodominantly on khajeh area in the vicinity of Tabriz The soil analysis from depths of 0-51 and 51-03 centimeter showed that Salsola dendroides could be stablished in a soil with the Ec of 14.55 ms/cm.In the second step, the seeds of Salsola dendroides and Salsola arbuscula were obtained in 1995 and those of Salsola rigida in 1997 from other provinces.In 1996 seeds of three perenial species Salsola tomentosa,Salsola arbuscula and Salsol adendroides were planted in plots and were transported to the field located in Bonab research Station in the Fall All species dried by the effect of high Ec and underground water level.
