Reactive species involved in higher seeds germination and shoots vigor through direct plasma exposure and plasma-activated liquids

TL;DR

This study investigates how cold atmospheric plasma treatments, via direct exposure and plasma-activated liquids, enhance seed germination and plant vigor by analyzing reactive oxygen species' roles.

Contribution

It introduces a comparative analysis of direct plasma exposure and plasma-activated liquids on seed germination and growth, emphasizing reactive oxygen species' effects.

Findings

Reactive oxygen species are key in improving germination.

Plasma-activated liquids enhance seed vigor.

Direct plasma exposure increases growth rates.

Abstract

Cold atmospheric plasma treatments have been applied on lenses seeds and shoots to improve their germination and vigor rates. Two approaches have been considered: direct plasma exposure and plasma activation of liquids (tap water, demineralized water and liquid fertilizer). A special focus has been drawn on reactive oxygen species generated in the plasma phase but also in plasma activated media to understand their impact on germination process as well as on plants growth.
