In order to study priming on seed germination, growth and physiological characteristics of Fenugreek plant under salt stress, a factorial experiment was conducted in a completely randomized design with three replications at the Seed Technology Laboratory Faculty of Agricultural Sciences Shahed University in year 2017. The treatments consisted of 5 levels of priming(control (no prime) and hydropriming distilled water for 24 hours, hydroperiming distilled water for 48 hours, 3% potassium nitrate and 5% salicylic acid) and Salinity stress in four levels (0, 50, 100 and 150 mM). The results of analysis of variance indicated significant effect of priming treatment and salinity stress on germination percentage and rate, rash parameters, photosynthetic pigments and proline content. The results of the comparison of the mean effect of interaction indicated that 24-hour hydroperimage application at salinity levels had an average of 100% germination percentage. Hydropriming had a superior advantage in terms of stem and root length, longitudinal seedling index, chlorophyll content, carotenoid content and prolin content with increasing salinity stress compared to other levels. The herbaceous plant seems to be resistant to stress. In general, the use of hydro-priming is recommended for modifying the stress of salinity in Fenugreek.
