Abstarct: Drought is one of the most important factors which affect on grow, yield and change some of physiological and morphological characteristics in plant. The application of new and non-destructive technologies for decreasing the negative effects of environmental stresses needs to new ways in agriculture. the use of pre-treatment of seeds by prime different solutions has increased seeds of plant speed and percentage of germination and ultimately caused better and faster establishment. In order to study the effect of pretreatment salicylic acid on germination and characteristics seedling growth of maizea a laboratory shut yon experiment as a completely randomized design with three replications was conducted at university of shahrood in 2013 and then an farm experiment as split plot in a randomized complete block design with three replications was conducted. Treatment consisted of three levels of drought stress including control (complete irrigation), no irrigation in the 3 weeks before flowering and no irrigation in 3 weeks after flowering and five levels salicylic acid control, 500, 1000, 1500 and 2000 is micromolar as sub plot. The results from laboratory study showed that priming significantly affected on germination so that acts of priming on germination percentage, germination rate, radicle length an plumule, root dry weight and stemlet at was significant at 1%. Results also this study showed that water stress during 3 weeks before and after flowering cause decrease chlorophyll, relative water content, leaf area and increased electrolyte leakage. Pretreatment of seeds, had positive impact on the speeds of emergence, chlorophyll, content relative water content, height plant, dry matter of leaf, dry matter of stem, leaf area and total dry matter. The interaction between salicylic acid and drought stress had significantly effect on chlorophyll, heigh plant and total dry matter. Pretreatment caused increasing dry matter in maize and decresed the drought stress.
