The Effect of Different Sodium Hypochlorite Concentrations on Seed Germination of Dracocephalum Moldavica L

Dracocephalum moldavica L. is an annual herbaceous plant, aromatic, medicinal, annual and is a member of the Lamiaceae family. The aim of this research is to find the best concentration and best exposure time of sodium hypochlorite solution with seeds of Dracocephalum moldavica for evaluation on seeds germination. Five different concentrations (0.5, 1, 2, 3, 4 and 5%) in different exposure times (2, 4, 6 and 8 min) were used. For germination of D.moldavica L. seeds the basal MS medium was used. This study was performed by random completely design with three replications for each treatment and analyzed with completely randomized design. Follow by the sterilization in different conditions, the seeds were completely placed on MS medium under sterilized conditions and the germination percentage was measured after one month. The best germination percent obtained at 4% of sodium hypochlorite solution concentration in 8 min exposure time (up to 90%) and the lowest germination percent obtained while used the concentration 0.5 and 5% of sodium hypochlorite solution in all mentioned time (without any germination).
