Prospective Applications of Low Frequency Glow Discharge Plasmas on Enhanced Germination, Growth and Yield of Wheat

摘要: Medium pressure (~ 10 torr) low frequency (3–5 kHz) glow discharge (LFGD) plasmas were applied to treat wheat (Triticum aestivum) seeds investigate the effects on water absorption, seed germination rate, seedling growth and yield. The LFGD produced with air air/O 2. Optical emission spectroscopic diagnostic methods revealed that \({\text{N}}_{2} \left( {{\text{C}}^{3}\Pi _{\text{u}} - {\text{B}}^{3}\Pi _{\text{g}} } \right)\), \({\text{N}}_{2}^{ + {{\text{B}}^{2}\Sigma _{\text{u}}^{ {\text{X}}^{2}\Sigma _{\text{g}}^{ \right)\) {{\text{B}}^{3}\Pi {\text{A}}^{3}\Sigma air, O species along nitrogen 2 plasmas, respectively. SEM images surface architectures functionalities of modified due plasma treatments. Water absorption was found increase treatment time. 6 min provided 95–100% germination. plants grown from treated for 3 9 duration by showed highest activity dry matter accumulation. Total chlorophyll contents leaves, longest spikes number spikes/spikelet also increased. yield increased ~ 20% over control plasma. Overall results can significantly change architecture, wheat.
