Abstract: Ferula, originated from several Ferula plants, is an important ethnic miedicine used by Uyghur nationality in Xinjiang Autonomous Region. This study collected seeds of 3 Ferula plants namely F. dissecta, F. krylovii and F.sinkiangensis for a complehensive study on their seed exterior appearance, thousand seed weight, water uptake ability, germination charecteristics and temperature stratification treatment. The results indicated that seeds of these 3 Ferula plants had rapid water uptaking ability, but with different seed germination rates. F. dissecta seed could germinate at normal temperature, but seeds of F. krylovii and F.sinkiangensis had seed dormancy with different degrees. Low temperature stratification could breake seed dormancy. The high and low temperature stratification treatments could effectively improve seed germination rate. Under high temperature treatment(25℃/15℃) for 14 d, then followed by low temperature treatment(4℃) for 42 d, F. krylovii seed germination rate could reach 46%. After high temperature treatment for 42 d then followed by low temperature stratification treatment for 56 d, F.sinkiangensis seed germination rate could reach 64%.
