Effects of Priming Treatments on Germination Indices of Soybean Cultivars Under Osmotic Stress

This study aimed to investigate the effects of priming treatments on germination indices soybean cultivars under osmotic stress in a completely randomized design with factorial arrangement botany laboratory located Kordestan Province, Sanandaj, Iran. Experimental included three (control and gibberellin at concentration 0.04%), cultivar (Clark Hobbit), -1.5MPa) replications. The standard test was performed according guidelines presented by International Seed Testing Association (ISTA) some indices, including percentage, rate, uniformity, mean time up 10% (D10), were calculated end experiment using German program. In addition, growth enzymatic activities also evaluated this study. Results analysis variance indicated that triple interaction A×B×C had significant all lowest coefficient variation (equal 7.55) obtained for rate while its highest value 17.22) uniformity index. Concerning treatment, it observed values percentage (with averages 48% 0.12, respectively) application gibberellin. other words, treatment led increases equal 15.58 90.44% compared control respectively. increasing levels inverse relationship so -1.5 MPa significantly Decreased both Clark Hobbit cultivars. general, concluded mitigated adverse resulted an stressful conditions.
