Previous studies suggested that fast and uniform germination is important for good crop establishment.The present study was conducted to investigate the possibility of increasing germination characteristics by seed priming techniques.An Wall Mount Faucets experiment was conducted with three replicates and two treatments including: 2 different priming duration (8 and 12 hours) and 6 osmotic potential of PEG 6000 solutions (-0.8, -1,-1.
2,-1.4,-1.6 Mpa) and distilled water as Samsung RR39M7140WW RR7000M A+ Free Standing Larder Fridge 385 Litres White a control group).The priming solutions were prepared using polyethylene glycol 6000 (PEG).
Our results showed that the most effective osmotic potential in improving germination characteristics of Trifolium alexandrium is -0.8 MPa for 16 hours.
