Abstract

Bunium persicum is an important medicinal plant with dormant seed and it is established and distributed only in its natural habitats. This research was conducted, using a completely randomized design with 3 replications and two observations. Seeds were collected from Semnan province and stored for 2 weeks at 40C. Then seeds were imposed under chemically stimulator, soaking in 1) KNO3 (50mM), 2) K2SO4 (50mM) and 3) polyethylene glycol (PEG) (250g/l) for 72h, 4) gibberelic acid (500ppm) for 5h, 5) kinetin (100ppm) for 1h, 6) combination of gibberelic acid (500ppm) and kinetin (100ppm) for 1h, 7) control. Results showed that KNO3, K2SO4 and PEG had no significant effects on seed quality characters. Applying hormones as pre-treatment caused higher percentage of germination but combination of kinetin and gibberlic acid promoted germination, total speed of germination and vigor index
