Objective The seed of Asafoica fukang has dormancy phenomenon. This paper took Asafoica Fukang as the research object and discussed the technique of seed dormancy removal. Methods The seeds of Ferula fukangensis were subjected to two tests of dormancy removal： one was stratified at low temperature at 4℃, that is, the specimens were prepared at 5, 10, 15, 20, 25, 30, 35 and 40 days, and the germination experiment was conducted at 20℃. In the other, different concentrations of auxin (IAA), naphthalene acetic acid (NAA), gibberellin (GA3), abscisic acid (ABA), 2, 4-D and 6-BA (4, 4-D) and 6-BA (6-BA) were cultured at low temperature stratified for 30 days at 4℃, in addition, germination tests at 20℃ were also studied. Results After low temperature stratification at 4℃, dormancy could not be relieved for 5~15 days, and germination occurred after 20 days. With the increase of low temperature stratification time, the germination rate increased, and the germination rate exceeded 75% on the 35th day, but the difference between 35d and 40d was not obvious. After 35 days of low temperature stratification treatment, the dormancy of Asafoea seed was basically relieved. The seed germination rate of Asafoetida fukangensis was significantly higher than that of the control group at 100ppm6-BA. Conclusion Asafuela in Fukang area was treated with low temperature stratification for 35 days, which could basically release its dormancy. When the concentration of 6-BA is 100 ppm, it has a good synergistic effect with low temperature lamination.
