Abstract

This research was conducted in order to effects of seed PRIMING on GERMINATION traits of salt sensitive TRITICALE line (ET-82-8) under SALINITY STRESS conditions. PRIMING treatments were done by distilled water (Hydro primed) and different osmotic potential (-1, -1.5 and -2 Mpa) of NaCl and PEG6000 for 6, 12 and 24 hours compared with dry untreated seeds. The seeds were raised and dried after PRIMING, then planted in petri dishes. Salinity treatments were applied by different osmotic potential of NaCl (0, -0.5, -1 and 1.5 Mpa) in germinator with 20oC temperature. Factorial experiment was used in CRD with three replications. Results showed that GERMINATION rate, root and shoot length and seed vigour significantly increased when seeds hydro primed for 6 hours in no salt stress conditions comparing to no primed seeds, while root and shoot weight and seed GERMINATION was not affected. Seed hydro PRIMING for 24 hours negatively affected all traits in both no stress and salt stress conditions. Increased salt stress up to -1 Mpa hydro primed seeds for 6 hours showed better GERMINATION rate and vigour than no primed seeds. Seed osmopriming with NaCl and PEG6000 significantly increased length and weight of shoot compare to hydro primed seeds in moderate salt stress (-1 MPa).
