Salinity is one of the environmental factors limiting cultivation of ornamental violet (Viola wittrickiana cv. Queen Yellow Bee). This study was conducted as a factorial experiment in a completely randomized design with four replications at Islamic Azad University, Science and Research Branch in 2019. Studied factors were sodium selenate (0, 0.002, 0.004 and 0.008 mg/L), sodium selenate application (foliar application and soil application) and salinity stress (0 (control), 3 and 6 dS/m). The results showed that salinity significantly reduced flower height, flower number, stem diameter, flower diameter, fresh and dry flower weight, fresh and dry root weight, chlorophyll a and b. At salinity of 6 dS / m, the application of sodium selenate in soil increased the fresh and dry weight of flower by 11.34% and 10.39%, respectively, while the foliar application of sodium selenate increased fresh and dry weight of viola flowers by 25.10% and 25.41%, respectively. Chlorophyll a increased by 12.93%. in salinity of 6 dS / m with application of sodium selenate at 0.008 mg / l compared to control. In salinity stress of 6 dS / m superoxide dismutase enzyme reduced by 26.13%. when sodium selenate was used at 0.008 mg / l in comparison with control. Salinity stress increased the amount of chlorine and sodium in shoots and roots and decreased potassium. Foliar application of sodium selenate at 0.008 mg / L improved the growth of ornamental violet.
