Medicago ruthenica seeds were collected from Zhenyuan, Tianshui, and Jingtai of Gansu Province, China. The suitable germination conditions, the first and the last counting times of seed germination, and seed germination characteristics were determined. After soaking in 98% sulphuric acid for different periods, seeds were incubated at different temperatures and with different illumination conditions. Soaking for 30–35 minutes significantly improved the germination percentage and germination index. A constant temperature of 25°C was the most suitable for germination, followed by 30°C. Illumination for eight hours was conducive to seedling germination and cotyledon protrusion from the seed coat, which would facilitate seed health assessment. Prechilling did not significantly affect germination. The first and the last counting times of seed germination occurred on the sixth and the fourteenth days, respectively, at 25°C under eight hours of illumination.
