The Effect of Priming with Salicylic acid on Carthamus tinctorius under Salinity Stress Mahtab salehi* Horticultural Sciences and Engineering Department, University of Nahavand Email: mhtb.salehi@gmail.com Seed priming is nowadays being extensively used to improve seed germination and seedling emergence in a wide range of crop species [1] and is basically a physiological process in which the seeds are pre-soaked before planting which, by itself, allows partial imbibition though preventing the germination [2]. In order to study the effect of salicylic acid on germination of Carthamus tinctorius under salinity stress, this study was done as a factorial experiment using a completely randomized design with 5 levels of salinity (0, 2, 4, 6, 8 dS/m) and 3 levels of salicylic acid (0, 0.01, 0.1%) with 3 replications. The results showed that salinity had significant effect on stem length and fresh weight. The priming effect on germination percentage, root and stem length and fresh weight was significant. The most germination percentage, root and stem length and fresh weight was obtained without priming treatment that was not statistically different with 0.01% salicylic acid.
