Plasma activated water (PAW) is water that has been treated with plasma to improve seed germination and plant growth.
PAW is made by exposing water to an electrical discharge in a vacuum, air, or other environment.
How does PAW work?
Reactive species: The plasma treatment creates reactive oxygen and nitrogen species (RONS) in the water.
Plant signaling: These reactive species may participate in plant signaling pathways.
Metabolic processes: They may regulate metabolic processes and help plants respond to stress.
What are the benefits of PAW?
Seed germination: PAW can increase the percentage of seeds that germinate.
Seedling growth: PAW can improve the length, weight, and vigor of seedlings.
Plant development: PAW can help plants develop and fight off pathogenic bacteria and fungi.
Plant health: PAW can improve the amount of soluble protein in roots and photosynthetic pigment in leaves.
How is PAW made?
PAW can be made from tap water, distilled water, or demineralized water. The water is exposed to plasma in a reactor.
Notably, seeds treated with plasma-activated water for 10–15 min exhibited longer root and shoot lengths, increased fresh weight of plants, and improved seed germination compared to the control group.
Furthermore, the chlorophyll content in green leafy plants was enhanced when irrigated with plasma-activated water.
Lower PH actuality helps germination. Plasma activated water helps achieve that.
