Effect of Hydro-priming and Priming with Ascorbic and Salicylic Acid on Germination Traits of Dracocephalum moldavicaL. Varieties

AbstractInformation regarding the evaluation of priming treatments on germination traits of Dracocephalum moldavicaL. varieties is not available. Therefore, this assay was conducted during 2013 in Islamic Azad University of Sanandaj located in Kurdistan province of Iran. Twelve treatments resulted from a factorial combination of six priming method (factor A) and two varieties of moldavian dragonhead (factor B), arranged in a completely randomized design replicated three times. Factor A included 50 mg L-1Salicylic acid (SA), 100 mg L-1SA, 50 mg L-1Ascorbic acid (AsA), 100 mg L-1AsA, hydro-priming and control. Factor B included Kurdish landrace and SZK1 cultivar. Results showed that the highest and lowest emergence percentages were 90.1 % in Kurdish SA50 and 52.8 % in SZK1 AsA100 treatments, respectively. Hydro priming treatment increased the emergence rate index more than 100 mg L-1SA, 100 mg L-1AsA and control treatments. The highest shoot weight was 9.41 mg for Kurdish SA50 treatment and the lowest length, 1.24 mg was attributed to SZK1 control treatment. The highest (6.56 mg) and lowest (1.74 mg) radicle weight were observed in Kurdish-hydro-priming and SZK1-AsA100 treatments. The Kurdish landrace showed a favorable germination condition compared to SZK1 cultivar.
