ABSTRACT
In order to solve the problem of
low emergence rate of Bupleurum chinense seeds, and screen out the best
germination conditions, the seeds of Bupleurum chinense L. were treated with different
soaking time, germination temperature and exogenous regulating substances to
improve the germination rate. The results showed that the germination rate of
fresh water at 12 h was significantly higher than that at 8 h and 36 h; The germination rate of seeds treated with
constant temperature 15 °C and variable temperature 25 °C/15 °C (day/night) was significantly higher than that
of other temperature treatments. Seed soaking time and culture temperature also influenced seed
germination start day and peak day. Different concentrations of regulatory
substances could promote seeds germination. The germination rate of seeds
induced by 0.50 mg/L 6-BA was the highest, the start day and peak day were 4
days and 5 days earlier than control check (CK) respectively.
