Abstract

This experiment was performed to determine salt tolerance in Salsola dendroides, Alhagi persarum and Aeluropus lagapoides. Seeds were collected from Nouredin Abad Garmsar in a hot and dry climate. After determination of optimum temperarure for germination, effect of salt on percentage and rate of germination was measured. Results showed that increment of salt concentration caused delay in germination rate and decreased germination. Despite high tolerance of halophytes to salt, the maximum germination occurred in salt free medium. The highest and the lowest salt resistance were observed in Salsola dendroides and Alhagi persarum repectively.
