To study the effect of drought stress and priming with salicylic acid on growth and development morphological of black cumin ( Nigella sativa L.), a greenhouse experiment was conducted at college of Agriculture, Shahid Bahonar university of kerman in the autumn of the 2013. The experiment was conducted as a factorial based on randomized complete block design with three replications. The first factor was drought stress that included in three levels: no tension (90% field capacity), moderate tension (75% field capacity) and severe tension (50% field capacity). The other factor was included 4 concentrations of salicylic acid : 0 mm (hydro priming with distilled water), 0.25 mm, 0.75 mm and 1 mm salicylic acid for priming the seeds of black cumin. The results of this research showed that the drought stress on the number of leaves, leaf area index, the height of stem, the relative water content (RWC), dry weight of the plant and the fresh weight of the plant was significant. The effect of the salicylic acid on the height of the stem, the number of the leaves, leaf area index, (RWC) and dry weight of plant was significant. But In this research the effect of salicylic acid on the fresh weight of the plant was not significant and the effect of interaction of salicylic acid and drought stress was not significant .
