| الوصف: | Perennial ryegrass (Lolium perenne L.) seeds (caryopses) germinate at or near the soil surface, where water potential can fluctuate widely. This study examined germination of «Del Ray» perennial ryegrass seeds when imbibition was interrupted by dehydration prior to radicle emergence. Seeds were hydrated for 0 to 40 h (26 o C), dehydrated at atmospheric water potentials of -4, -40, -100 and/or -150 MPa for 4-168 h, then rehydrated. Germination (radicle elongation ≥1 mm), seedling growth, solute leakage, and endogenous abscisic acid (ABA) levels were measured. Treatment differences in final germination percentage, seedling growth, and solute leakage were generally not significant |
