Potential benefits of priming seeds were first indicated by Levitt and Hamm in 1943 (14), reported for vegetable seed in 1963 by Ells (7), and summarized in 1975 by Hey-decker et al. (11). Effective priming causes the treated seed to germinate earlier and with greater uniformity than untreated seed (11). To date, the technique of priming seeds has been used to solve problems concerning thermodormancy (9), cold soil temperatures (15), and to increase the rate and uniformity of crop emergence (7, 10, 11). However, the methodology of priming, especially for PEG solutions, has not been readily adaptable to handling the large amounts of seed that would be required for commercial use (4, 10). Although the successful use of the SPS to ‘bulk’ prime carrot (12) and pepper (3) seeds has been reported, the design of the SPS and the methodology of its use have not been adequately described. Therefore, this report describes the SPS and the methodology that makes it functional.
