[Abstract] Seeds of Bupleurum chinense cultivar，Zhongchai No.1， were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15，20，25，15-25 ℃) and light (8，12 h) to germinate，respectively. The lower constant temperature (15 ℃) and the higher constant temperature (25 ℃) were not conducive to the sprouting characteristics of B. chinese. While they were able to enhance root activity to some extent； The seeding growth of B. chinese was significantly better in the variable temperature than correspondence in the constant temperature， significantly. The emergence speed， emergence index， vigor index and root activity of Bupleurum were improved under the 12 h of light-time， but the germination rate was not improved. The sprouting of Bupleurum′s seeds could be improved to some extent by soaking with hormone， such as gibberellin， cytokinin， salicylic acid. Gibberellin promoted seeds′ sprouting and seedings′s root activity of Bupleurum， while salicylic acid increased the root activity of seeding. There is a significant influence of light， temperatures and hormone treatment on the germination of Zhongchai No.1 seeds， and all three are remarkably interacted； It is beneficial to promote seed germination by the temperature (20±5) ℃， lighting (8 h) and gibberellin concentration (10×10-6).
