Background: This study was conducted to determine the effect of temperature, light, hormones, and after-ripening treatment on Rehmannia glutinosa seed germination to provide valuable information for its breeding and cultivation.
Methods and Results: The seeds used in this study were harvested from the ‘Jihwang-1-ho’ cultivar. The seed length and width were 1.13 ± 0.03 ㎜ and 0.86 ± 0.02 ㎜, respectively, with a seed coat characterized by polygonal cells. The germination efficiency was evaluated at various temperatures (15, 20, 25, and 30℃) and light conditions (light/dark). The optimal germination condition was found to be 25℃ with light (91% germination). Pre-soaking the seeds with gibberellic acid (GA₃) increased germination, and the highest germination (72%) was observed with 1,000 ㎎/ℓ GA₃. Additionally, this also increased the mean germination time , germination uniformity, and germination index. The seeds that matured at 45% and 70% relative humidity showed the highest germination rates at 32 and 24 weeks, respectively.
Conclusions: The best method for R. glutinosa seed germination is maintaining 25℃ under light conditions with after-ripening treatment for over 16 weeks. Pre-soaking the seeds in 1,000 ㎎/ℓ GA₃ for 24 h further improved their germination. Rehmannia glutinosa seeds were classified under non-deep physiological dormancy.
