Background: This study was conducted to investigate the effects of germination temperature, storage container and storage temperature on Scrophularia buergeriana and Scrophularia takesimensis seeds. Methods and Results: Seed lengths of both species were 0.8 ㎜, while seed width differed, with S. buergeriana measuring 0.5 ㎜ and S. takesimensis measuring 0.4 ㎜. The seeds of S. buergeriana were packaged in paper containers under room temperature (15Celsius), cold temperature (4Celsius), and freeze temperature (−20Celsius). These seeds exhibited around 80% germination rate at temperatures between 15℃ and 30Celsius. The germiantion rate of S. takesimensis, on the other hand, differed significantly at different germination temperatures. Seeds of S. takesimensis which were packaged in vinyl and paper containers and stored under room and cold temperatures, exhibited around 80% germination rate at 15Celsius. However, the germination rate of freeze-stored seeds were decreased to lower than 20% at germination temperatures of 15Celsius, 25Celsius and 30Celsius germiantion conditions. The rate of germination showed a low positive to a significantly negativie correlation with the other factor that were determined to evaluate the germination performance. Conclusions: This study elucidates the most suitable germination and storage conditions to increase the germination rate for the two species of Scrophularia buergeriana and Scrophularia takesimensis needs to be stored in paper containers under cold temperature and requires a temperature of 20Celsius for germination. On the other hand, S. takesimensis in vinyl containers need to be stored at room temperature and those in paper containers at cold temperature, and a temperature of 15Celsius is required for germination.
