Abstract
This research was conducted for evaluation of germination treatments and favorite planting date of three medicinal plant species including Dorema (Dorema ammoniacum), Asafetida (Ferula assa-foetida) and Galbanum (Ferula gummosa) in Agricultural College of Ferdowsi University of Mashhad in 2008. Effect of different levels of temperature and washing on germination percent and rate of species were evaluated in first experiment. Temperature in 6 levels including 1, 4, 7, 10, 13 and 20 °C and seeds treatment in 3 levels including drench, washing and extract were surveyed. In the second experiment, emergence condition of species in four planting dates including first December, first January, first April and first May in pot and out door conditions were evaluated. Result showed that, optimum temperature for germination of Dorema, Asafetida and Galbanum plants were 7.83, 8.27 and 3.14 °C, respectively. Further, germination percent of each plant had a positive and significant relation (p
