“…With the enactment of the Nagoya Protocol, biodiversity and biogenetic resources are highly valued, and efforts are being made to develop and industrialize native plants (Oh et al 2018). E. jolkinii is a medicinal plant material, and leaves and stems have been used as medicinal materials in oriental medicine.…”

“…In addition, the unique, large flower structure and herbivorous form of E. jolkinii are considered to be of high ornamental value. To this end, researchers have evaluated the environment and growth characteristics of native habitats (Shin et al 2018a), the vase life of cut flowers (Oh et al 2018;Song et al 2019a), cuttings for propagation (Shin et al 2017), and cultivation according to pot size and nutrient conditions (Shin et al 2018b). However, the dormancy characteristics of seeds and the conditions and characteristics of seed germination have not yet been reported.…”

Background Euphorbia jolkinii Boiss. is a perennial species native to Jeju Island and the southern coastal area of Korea. Particularly on Jeju Island, the yellow flowers of E. jolkinii Boiss. have a high ornamental value because of their contrast with basalt. This study was conducted to investigate the effects of different temperatures (5, 15, 20, and 25 °C) and gibberellic acid (GA3) concentrations (0, 10, 100, or 1000 mg/L) on seed dormancy and germination of E. jolkinii. In addition, we classified the seed dormancy type and compared types with those of other species in the same genus. Results The number of seeds with viable embryos and endosperms was approximately 66%. The final germination percentages at 5, 15, 20, and 25 °C were 51.7%, 83.5%, 2.6%, and 0.0%, respectively. In GA3 concentration experiments, the final germination percentages of 0, 10, 100, and 1000 mg/L were 83.5%, 91.7%, 79.1%, and 83.4%, respectively, at 15 °C conditions, and 0.0%, 6.9%, 13.2%, and 27.3%, respectively, at 25 °C. Conclusions Germination improved at temperatures of 15 °C or lower. Furthermore, GA3 treatment effectively reduced germination times. Thus, the seeds of E. jolkinni were classified as having non-deep physiological dormancy.
