In order to evaluate the foliar spraying of spermidine on vegetative growth traits of Black cumin (Nigella sativa L.) under salt stress, an experiment was conducted as factorial design based on complete random design (CRD) with four replications in research greenhouse of agriculture college of Vali-e-Asr university of Rafsanjan. Treatments were included Salinity (0, 30, 60, 90 mMol) and foliar spraying of spermidine (0, 1, 3, 5 mMol). The charactristics studied in this experiment included leaf number, stem hight and shoot biomass. results showed that stem hight and shoot biomass were significantly affected by the interaction between salinity and foliar spraying of spermidine. As salinity levels increased, traits decreased but at each salinity level, foliar application of spermidine had a positive effect. leaf number was only significantly affected by salinity treatment and leaf number reduced by increasing salinity stress. results showed that, foliar spraying of spermidine improved growth of Black cumin under salinity stress.
