Linum usitatissimum L. is an annual herb that is cultivated in the area of East and West Azarbaijan in the local name of locust. Due to the increasing amount of salinity in Azerbaijani lands, in order to study the effect of salinity on germination of two varieties, brown and golden yellow flax, a factorial experiment designed with three replications. The seeds first Disinfected with sodium hypochlorite 10% for 5 minutes and so washed with distilled water. Then seeds placed in sterilized petri dishes. Salinity treatments were performed at 4 levels of zero (control), 50, 100 and 200 mM of NaCl by adding 3 milliliters of saline solutions to each petri. Petri dishes placed in the germinator at 25 ± 2 °C and in relative humidity of 30%. The number of germinated seeds studied on the seventh day. The results showed that salt concentration affect the different varieties of flax in different manner, so that in yellow flax with increasing salinity, germination percentage decreased significantly, but brown seeds germination was less affected by salinity. According to the obtained results, it is possible to use flax varieties with brown seed color for salting in lands up to 200 mM of sodium chloride.
