        In order to evaluate the effects of differents treatments on seed, dormancy breaking treatments on fennel, germination stimulating and seeding growth on two fennel varieties ( Shiraz  and Bushehr). In one experiment was conducted as spilet factorial in compeletly randomized design with four replications in seed technology research  laboratory  of  Islamic  Azad University (Isfahan  Branch) in 2014. In the experiment cold stratification levels were main plots  and  factorial  of vareties and dormancy breaking treatments were subplots. Cold strification treatments include moist chilling for 0, 15, 30, and 45 days. Fennel varietieswere Shiraz and Bushehr. Dormancy breaking treatments  included  the  following: 10 µm  6-benzylaminopurine  (BA);  10 FM kinetin (KI); 6-benzylaminopurine +gibberellic acid, gibberellic acid + kinetin , kinetin+6-benzylaminopurine;  gibberellic acid  +  6-benzylaminopurine + kinetin  ( with  the  same concentrations), distilled  water ; 0/4 percent Aminol- Forte fertilizer. Chilling significantly  increased  , germination  percentage (GP),  coleoptile length (CL),  radical l ength (RL), germination rate (GR), and seed - vigor index (SVI) (P>0.05). The highest values of these traits were treated for 15 days stratification. The effect of  dormancy breaking  treatments  on  all traits  except germination uniformity and  germination rate was  significant  at  (P> 0.01) Treatments with BA, KI, Amino l - Forte, and distilled  water  significantly  increased all the Characteristic  parameters  of  fennel  germination  compared  with  those  of other treatments. The Shiraz variety had significantly greate, GP, CL, RL, and SVI than  those  of  the  Busheh Variety  (P>0.05). Manuscript profile
