Carrot seeds (Daucus carota L.) ‘Jawa’ were soaked for 12 hours at 20°C in water and 0.5%, 1.0%, 1.5%, 2.0%, and 2.5% solutions of the hydrochloric acid (HCl). The seeds were then dried for 24 hours at 20°C and tested for their germination capacity and seed state of health. Treating the seeds with 0.5% HCl increased their germination energy (57.0%) and capacity (63.3%) in comparison with non-treated seeds: 45.0% and 47.7%, respectively. The concentration of the HCl above 0.5% did not affect the germination capacity, but decreased the maximum germination and above 1.0% increased the percentage of dead seeds. All concentrations of HCl improved the state of health of the seeds.
