Анотация: The aim of this study was to enhance the germination percentage and rate of Ferula assa foetida, a medicinally important vulnerable species, which have a low germination rate under normal laboratory conditions. The efficacy of different treatments including various levels of GA3, chilling and soaking with running water for germination improvement was tested. Analysis of variance indicated that Cold stratification and GA3 concentration had significant effects on seed germination percentage. Combined treatments chilling (4 C.) for both periods of 30 and 60 days were most effective in breaking dormancy. Among the combined chilling treatments, Maximum germination was obtained at combination treatment cold stratification (60 days) with 2000 ppm of GA3 solution and minimum germination was at socking in running water and control treatments. These results suggested that Ferula assa foetida seeds exhibit endogenous dormancy. A combination of cold stratifications and exogenous application of GA3 alleviated seed dormancy in a relatively short period of time. Germination rate was positively correlated with germination percentage
