Growth of Phaseolus vulgaris in Response to Seed Priming by Plasma-Activated Water in Laboratory Screening and Outdoor Pot Trial

TL;DR

This study investigates how plasma-activated water influences the growth and physiological responses of Phaseolus vulgaris, showing benefits in outdoor conditions despite no germination effects in laboratory tests.

Contribution

It demonstrates that plasma-activated water improves bean seedling growth and antioxidant activity in pot trials, highlighting its potential for field farming applications.

Findings

Increased seedling length and biomass in PAW-treated plants

Higher activity of antioxidant enzymes such as SOD, G-POX, CAT, APX, and GR

No germination improvement observed in laboratory trials

Abstract

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.
