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 length of the main root, the length of secondary roots, the number of the
secondary roots and was significant. The effect of the salicylic acid on the length of the secondry
root, and was significant. But In this research the effect of salicylic acid on the length of the main
root and the number of secondary roots was not significant and the effect of interaction of salicylic
acid and drought stress was significant on
