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).
