Growth of Phaseolus vulgaris in Response to Seed Priming With Plasma‐Activated Water in a Laboratory Screening and Outdoor Pot Trial

This study explores plasma‐activated water (PAW) effects on Common bean growth in laboratory and pot trials. Three treatments were assessed: PAW priming, spraying, and their combination. Laboratory trials showed no germination improvement. However, pot trials revealed notable increases in seedling length, biomass, and antioxidant enzyme activity. Enzymes SOD, G‐POX, CAT, APX, and GR showed significantly higher activity in PAW‐treated plants. These effects were linked to reactive oxygen and nitrogen species in PAW. Findings suggest PAW enhances bean growth and physiology, supporting field farming applications.
