Abstract
In order to study the effect ofhormonal andphysical priming techniques on seed germination and seedling establishment of wheat, an experiment was conducted in Islamic Azad University, Tabriz, Iran, in 3 replications during 2012-13. Studied factors were hormonal seed priming materials(gibberlic acid and kinetin in 50, 100, 150 and 200 ppm concentrations) and physical seed priming agents (ultrasonic, laser, magnetic field, gamma and beta radiations for 5 and 10 minutes) included control. Results indicated that those seeds treated in gibberlic acid and kinetin of 50-150 ppm germinated faster. Except of 50 ppm gibberlic acid and kinetin of, other treatments had lower seedling dry weight. Effect of laser and magnetic field for 5 minutes was effective on time to final germination than other treatments. Seedling from magnetic field for 5 minutes had greater vigor than ultrasonic and beta. Wheat seeds priming before sowing with gibberlic acid and kinetin or laser and magnetic field is recommended.
