This experiment was conducted to investigate the effects of hydropriming and osmopriming on germination rate, percentage of, root–shoot length and root–shoot weight of fennel (Foeniculum vulgare) seeds. Priming was done by: hydropriming with distilled water, . osmopriming with NaCl at four levels (-0.3, -0.6, -0.9, -1.2 MPa), osmopriming with K2SO4 in four levels (-0.3, -0.6, -0.9, -1.2 MPa), priming with PEG6000 in four levels (-0.3, -0.6, -0.9, -1.2MPa) and 5. seeds with unprime control at treat. In this study, RCBD experimental design was used for the analysis of experimental factors. The results showed that priming significantly effected at all treatment methods. Maximum and minimum germination percentage were obtained with PEG (-0.9 MPa) applied, and in control. Maximum and minimum germination rates were obtained when K2SO4 (-0.3 MPa), NaCl (-0.3 MPa) were used. Maximum and minimum root length were obtained when NaCl [(-1.2 MPa), PEG (-0.3 MPa)], NaCl (-0.6 MPa) were used. Maximum and minimum shoot length were obtained when PEG (-0.3 MPa), NaCl (-0.6 MPa) were used. Maximum and minimum root weight, root/shoot length were obtained when NaCl (-1.2 MPa), NaCl (-0.6 MPa) were used. Maximum and minimum shoot weight were obtained when NaCl (-1.2 MPa), NaCl (-0.3 MPa) were used. Maximum and minimum root/shoot weight were obtained when [PEG (-0.3 MPa), K2SO4 (-0.3, -0.6, -0.9 MPa), NaCl (-0.6, -0.9 MPa), hydropriming] and [PEG (-0.6, -1.2 MPa), NaCl (-1.2 MPa)] were used.
