conditions for germination of medicinal plants seed is
essential for their cultivation. Therefore, to evaluate the
effect of different treatments on seed germination of two
medicinal species, Descurainia sophia and Plantago
ovata collected in 2009 from Tehran Province, an
experiment with a factorial randomized complete block design
in 6 treatments with 4 replications was conducted.
with concentrations of 0.1, 0.2 and 0.3%, acetylsalicylic
acid with levels of 50 and 100 mg/l, prechilling
for 10 days), thiourea with levels of 0.1 and 0.2%, boiling
water for 5 and 10 min. To compare, distilled water was used
as control. Results showed that the effect of different
treatments on germination percentage of two medicinal
species was significantly different (p < 0.05). It was shown
that prechilling was the most effective treatment on seed
germination of both species.
