This study aimed to determine the reactions of five F-1 hybrid ornamental kale cultivars (Red Pigeon, Victoria Pigeon, Red Chidori, White Kamome, and Pink Kamome) to in vitro salt stress during germination and emergence. Sterilized seeds were cultured on Murashige and Skoog (MS) media containing four different NaCl doses (0, 3, 7, and 12 dS/m). According to the obtained results, the germination rate, speed of germination, average germination time, germination index, and sensitivity index values were 42.72-97.09%, 0.76-3.43, 3.08-6.80 days, 6.60-41.28, and 0.81-1.51, respectively. Emergence rate, speed of emergence, the average emergence time, emergence index, hypocotyl length and radicle length values were detected as 11.99-93.78%, 0.16-1.63, 4.97-8.69 days, 1.45-18.75, 0.39-3.27 cm and 0.68-3.43 cm, respectively. The F-1 Red Pigeon and F-1 Victoria Pigeon were the most salt stress resistant cultivars, while the F-1 White Kamome cultivars were the most susceptible to salt stress. Increasing the NaCl dose had a statistically significant negative effect on both the germination and emergence properties of the cultivars.
