dc.description.abstract <p>A new method is demonstrated for using concentrated oxygen (O<sub>2</sub> gas) to release seed dormancy. Concentrated O<sub>2</sub> gas in air is known to release seed dormancy in some seeds, including some foxtail (<em>Setaria</em>) species. New medical equipment makes O<sub>2</sub> gas easier to work with than before, so laboratories working with dormant seeds can now use concentrated O<sub>2</sub> gas as a seed treatment on a production basis. Use of medical O<sub>2</sub> gas concentrators is simpler and safer than using O<sub>2</sub> gas supplied by pressurized gas cylinders. Suitable medical O<sub>2</sub> gas concentrators in new or used condition are readily available, operate on standard electrical current, and deliver O<sub>2</sub> gas with low-pressure tubes and fittings. Resealable plastic bags are inflated with concentrated O<sub>2</sub> gas and then sealed as seed treatment chambers. This use of concentrated O<sub>2</sub> gas is confirmed to significantly increase the germination of dormant seeds of giant foxtail (<em>Setaria faberi</em> Herrm) and plains bristlegrass (<em>S. macrostachya </em>Kunth).</p>
