The experiment was conducted to investigate the effects of pre-sowing treatments on germination and vigour of wheat (Triticum aestivum L.) cv. Auqab-2000 seeds. Seeds were subjected to hydropriming for 2, 12, 24 or 48 h, osmoconditioning with -1.1 MPa polyethylene glycol (PEG-10,000) for 24 or 48 h, salt priming with -1 .1 MPa KNO3 solution for 24 or 48 h and chilling stress at þ 20 degree centigrade for 12 or 24 h. Hydropriming treatment for 48 h showed maximum invigoration than all other treatments including control with increased germination and seedling root shoot weight and lesser mean germination time (MGT) and time to 50% germination (T50). PEG treated seeds completely lost their germination ability: KNO3 treatment decreased the seed vigour by reducing the germination percentage and increasing T50 and MGT.
