Seeds of 'Ace 55' tomato (Lycopersicon esculentum Mill.) and 'Mary Wash- ington' asparagus (Asparagus officinalis L.) were primed in -0.8 MPa (20C, 1 week, dark) polyethylene glycol 8000 (PEG), synthetic seawater (INO), or NaNO 3. Primed seeds of both species had a higher percentage of germination than untreated seeds only at 10C in nonsaline ( - 0.05 MPa) medium, while in saline medium ( - 0.6 MPa) priming increased the percentage of germination of tomato seeds at 10 and 30C, and of primed asparagus seeds at 10 and 20C. Sodium nitrate was superior to PEG or IN0 for priming tomato seeds since it resulted in fewer days to 50% germination and higher final germination percentage in saline media at all temperatures. IN0 was a satisfactory alternative to PEG or NaNO 3 for priming asparagus seeds since priming agent had little or no effect on germination. Seedling emergence from NaNO 3-primed seeds of both species sown in a seedbed provided saline (- 0.39 MPa) irrigation was faster than from untreated dry-sown seeds. In the saline seedbed, priming increased final emer- gence percentage (FEP) from asparagus seeds, provided they were not subsequently dried, but had no effect on the percentage emergence of tomato seeds. Fluid-drilling primed or germinated seeds of either species enhanced seedling establishment in the saline seedbed by reducing time to 50% emergence and/or increasing FEP relative to primed, dried-b&k or untreated seeds. Priming involves exposing seeds to an ex- ternal water potential low enough to restrict germination and yet permit pregerminative physiological and biochemical activities (Bradford, 1986). Commonly used priming agents include inorganic salts such as CaCl 2,
