Abstract
Diffuse coplanar surface barrier discharge (DCSBD) at atmospheric pressure in ambient air was used for plasma treatment of agricultural seeds. The aim of plasma treatment was improvement of wettability and potential reduction of pathogens. Lettuce seeds were plasma treated for a few seconds and analyzed with SEM, XPS and method for measurement of water uptake. Surface morphology was not affected with plasma treatment. Plasma treatment caused surface chemical changes and improvement of water uptake with only slight decrease of germination in comparison with untreated seeds. Change in percentage of chemical bonds containing carbon and oxygen was observed. Significant increase of O/C ratio after few seconds of plasma treatment was reached.
