Abstract: Pregermination techniques of osmotic priming and hydropriming have been used to enhance seed performance on planting Osmotic priming and hydropriming method were compared on the basis of germination performance O 2 , N 2 and air were supplied to 500 ml vessels containing seeds with distilled water or -1.31 MPa PEG solution for 10 days On removing seeds from vessels, seeds were dried back to original water content. There were no differences in total germination between osmotic priming and hydropriming treatments t50 was reduced dramatically from 112 to 32 hours, using hydropriming with air and N 2 supply for 1 day, compared to 70 hours of osmotic priming. Solute leakage from O 2 supply of both methods was higher than air or N treatment, Indicating the loss of membrane integrity Hydropriming with O 2 induced radicle emergence and loss of desiccation tolerance around 28 hours after treatment LEA protein levels were not changed in both treatments except for hydropriming with O 2 . The timing of desiccation tolerance loss was correlated with that of degradation of LEA protein. O 2 supply caused the adverse effects on seed performance from both methods 1 day after treatment
