Aim and Background:
(Satureja sahendica) is one of the most important medicinal and edible plants. Priming is a technique that a seed obtained all physiological and biochemical requirement for germination before planted in the ground.
Material and methods:
In order to evaluation of seed priming on moderating salinity effect on germination and primary growth of Savory in pot planting, an experiment carried out by Factorial design with RCD at three replication in greenhouse of Islamic Azad University of Khoy in 2014. The first factor was salinity at three level (EC=2, 4 and 6 mmohs/cm  of NaCl ) and second factor was seed priming in four level control, KNO3  (2.5%), KCl(2 %)and NaCl(1 %).Traits investigated include the length of root and shoot, shoot and root dry weight, germination percentage, mean germination time and the dry weight of the biomass.
Results:
The variance analysis of data showed that salinity treatments significantly affected all investigated traits. Also interaction of salinity and priming on germination percentage was significantly affected. The highest percentage of germination (92.84%) obtained under KNO3 × 2 mmohs/cm NaCl concentration. The treatment of KCl × 2 mmohs/cm concentration with 92.56 has the highest percentage of germination.
Conclusion:
According to this results Savory cultivation not recommended for Areas where the irrigation water is saline. And if water salinity is low, seed priming with KNO3 can moderated salinity effects on Savory seed germination. The interaction of two factors was significant on germination.
