Abstract

Abstract : Recent reports indicate that atmospheric cold plasma (ACP) treatment of seeds can enhance their germination, however, the mechanisms of action are not yet entirely clear. In the present work, we report on the effects of plasma treatment on wheat seed germination and seedling growth. Additionally, changes in the surface chemistry and characteristics of the wheat seeds exposed to plasma were investigated. Treatments of 30–60 s significantly enhanced the germination rate and showed positive effects on seedling growth. ACP resulted in changes of seed surface and chemical characteristics including water uptake and contact angle values. Changes in seed pH and total titratable acidity, as well as nitrites, nitrates, and malondialdehyde concentrations were also recorded. Abstract : In the present work, we report on a stimulative effect of plasma treatment on wheat seeds germination and seedlings growth. To provide insights into the mechanisms resulting in germination enhancement by cold plasma, changes in the surface chemistry and characteristics of the wheat seeds exposed to ACP were also investigated.
