The effects of seed priming by three antigibberellins on wheat ,cv. Azar 2, flag leaf traits were investigated under regular irrigation condition. Experimental treatments included untreated seeds or control treatment, seed priming with distilled water (hydropriming), priming by chlormequat chloride (including 400, 800, 1200 and 1600), paclobutrazol (including 35, 70, 105 and 140) ancymidol (including 10, 20, 30 and 40 μM). Results showed that seed priming induced significant differences on flag leaf dry weight, length area and specific leaf weight and stomata density of upper lower side of leaf. Among our applied substances, cholrmequat chlorid in 400 and 800, paclobutrazol in 35 and 75 and ancymidol in 20 μM had highest amount in leaf area and length. The treatment of 20 μM of ancymidol had highest leaf dry weight and SLW compared to other treatments. In all of ancymidol and paclobutrazol stomata density was lower than control treatment in upper side of leaf. Also, seed hydropriming enhanced all traits compared to control treatment.
