Numerous works have demonstrated that cold plasma treatments constitute an effective procedure to accelerate seed germination under nonstress conditions. Evidence also exists about a positive effect of plasmas for environmental stress For barley seeds, this work studies the influence on rate and initial stages plant growth in common environments, such as drought, salinity, low-temperature As general result, it has been found was higher plasma-treated than untreated seeds. Plasma induced favorable changes radicle dimensions, which depended environment. The obtained results demonstrate affects biochemical metabolic chains seeds plants, resulting concentration growing factors, faster germination, initially more robust growth, even These phenotype are accompanied by differences biomarkers photosynthetic pigments (chlorophylls b carotenoids), reactive oxygen species, and, particularly, amino acid proline leaves young with depend conditions application treatment. This supports idea that, rather increase water imbibition capacity, there clear beneficial effects seedling treatments.
