| Abstract: | Lettuce seeds were germinated at different hydrostatic pressures and O2 concentrations. Some combinations of pressure and O2 concentration stimulated while others retarded germination. The highest germination rates which occurred with pressure application and added O2 were equalled at atmospheric pressure if the O2 concentration was increased sufficiently. Increasing pressure generally retarded germination, but the pressure effect was partly offset by added O2. Sustained pressures affected subsequent germination after pressure was released, but only when O2 was present. Seeds to which pressure was applied in the absence of O2 germinated as well after pressure exposure as untreated seeds. |
