Abstract :Abstract This study was conducted to evaluate the effects of azelaic acid (AzA) priming on germination and some seedling parameters for seeds of barley (Hordeum vulgare L.) under salt stress conditions. In current research, four different salinity levels (0 mM NaCl; (control: pure water), 25 mM NaCl, 50 mM NaCl, 100 mM NaCl) and 2 different doses of AzA (0 mM, 0.5 mM), with 3 replicates were examined according to a complete randomised design. The seeds of Larende barley variety was used as plant material. Analysis of variance showed that the effect of AzA priming on shoot length, root fresh weight and shoot fresh weight of barley was significant (p ≤ 0.01), while the effect on other parameters was found insignificant (p ≥ 0.05). NaCl levels significantly affected all parameters (p ≤ 0.01). In the AzA × NaCl interaction, root fresh weight, shoot fresh weight, salt tolerance index and relative water content were affected significantly (p ≤ 0.01). In examine the effects of salinity levels on barley plant, especially on germination parameters, the values obtained from 0, 25 and 50 mM applications were in the same significance group. According to this result, when evaluated in terms of germination, it was concluded that water having 50 mM or less salt content can be used in barley cultivation. It is thought that it would be appropriate to try AzA at different doses and different salt levels in order to understand the effects of AzA treatment more clearly.
