For its specific physical and physicochemical properties, the water treated with low-frequency low-pressure
glow plasma (GPTW) affects the growth of plants and enhances the phytoavalibility of selenium (Se) ions
from the nutrient solution. The basic biometric and physiological parameters of cucumber and the uptake of
Se ions applied as selenate (Na2SeO4) from the nutrient solution prepared using GPTW or distilled water
(DW) were compared. In the presence of Se, the fresh weight (f.w.) of shoots of plants growing in waterdifferentiated
nutrient solutions did not differ, whilst their dry weight (d.w.) and leaf area (LA) were higher
in plants grown in the GPTW- than in DW-containing medium. The use of GPTW for preparation of the
nutrient solution was associated with a substantial improvement of Se ions phytoavailability, compared to
the regular growth medium based on DW. Despite the higher Se bioaccumulation in the GPTW- than in
DW-based medium, the phytotoxicity of this element was not enhanced. GPTW-induced Se accumulation
was remarkable and hence recommended for further study to understand the detailed mechanism
GPTW action.
