Abstract
The germination behaviour of unsoaked, hydroprimed and thiourea primed seeds (TU,750, 1000 and 1250 ppm) in water , polyethylene glycol (PEG, -0.2 and -0.4 MPa ) and NaCl (30 and 50 mM) was investigated. The percent germination and seedling growth of TU primed seeds was best compared to other treatments under stressed conditions. The root/shoot ratio increased with stress in all seedlings and vice versa for seedling vigour index. TU primed seeds exhibited the highest tolerance index (85) under - 0.2 MPa PEG treatment and 40 tolerance index under 30mM salinity stress. Priming with thiourea @1000 ppm was the most effective in ameliorating water and salinity stress.
