Abstract

Abstract : The paper presents experimental results concerning pre‐sowing stimulation of Thuringian Mallow ( Lavatera thuringiaca L.) seeds with non‐thermal plasma generated in GlidArc reactor (dry nitrogen, atmospheric pressure) and its effect on the germination process. Five groups of seeds characterized by different exposure times were used. The effect of cold plasma on seeds was analyzed by investigation of microscopic pictures of carbon coated seed surfaces registered by means of electron scanning microscope. Visible changes in the seed surface structure could enhance the formation of micro‐pores which may be involved in water absorption, thus facilitating faster seed germination. Pre‐sowing plasma stimulation of seeds improved germination parameters such as germination capacity and germination energy for all tested groups, relative to control. The highest germination parameters were obtained for seeds stimulated with plasma for the exposure times of 2 and 5 min. Abstract : Pre‐sowing stimulation of Thuringian Mallow ( Lavatera thuringiaca L.) seeds with non‐thermal plasma generated in GlidArc reactor (dry nitrogen, atmospheric pressure) and its effect on the germination process was investigated. The plasma effect was analyzed by application of water contact angle measurements and by investigation of carbon coated seed surfaces registered by means of electron scanning microscope. The highest germination parameters were obtained for seeds stimulated with plasma for the exposure times of 2 and 5 min. Statistical analysis of the data showed significant impact of GlidArc plasma on the seeds germination parameters of Thuringian Mallow.
