1 DPHE - Diagnostic des Plasmas Hors Equilibres

Non-equilibrium plasmas have been studied to be used in agricultural applications. Synthetic air plasmas were generated at 1 Pa in an 80 litres vacuum chamber by an ECR coaxial microwave source at 2.45 GHz. Plasma characteristics were determined by OES and Langmuir probe measurements. Tomato seeds adding showed no influence on plasma characterizations. A 12% increase in germination rate was measured after 14 days following a plasma treatment of 10 min at 50 W.
