Abstract :
A laboratory experiment was carried out to determine the effects of seed priming (NP: non prime and P: prime with zinc sulphate) on seed germination characteristics and seedling growth of chickpea under different levels of salinity stress (0, -2, -4, -6, -8 and -10 bar). Therefore, a factorial experiment was used based on completely randomized design (CRD) with three replications. Results indicated that, with increasing salinity stress germination characteristics such as germination percentage, germination rate and seedling fresh weight decreased, but decreasing amount of these characteristics in primed seeds were less than non-primed. In comparison with control (NP treatment) at all salinity levels, P treatment showed more germination rate and seedling fresh weight. Also, germination percentage in P treatment was more than control. In general, it is concluded that seed priming improved germination characteristics of chickpea under salinity stress conditions and increased the resistance of chickpea to salinity stress at germination phase.
