Abstract

U ovom radu ispitan je učinak plazma aktivirane vode (PAW) na germinaciju ječma (Hordeum Vulgare cv Golden Promise) nakon šest dana inkubacije. OdreĎivani su fizikalno kemijski parametri tretirane vode te je praćen učinak na stupanj klijavosti i koncentraciju ukupnih pigmenata. Uzorci vode tretirani su hladnom plazmom pri tri frekvencije: 60, 90 i 120 Hz uz upuhivanje plinova: argon, zrak, kisik i dušik. Tretmani su provedeni u trajanju deset minuta za uzorke u kojima su upuhani argon i zrak te... More dvadeset minuta za uzorke u koje su upuhani kisik i dušik. Ovim eksperimentom je dokazano da najpovoljniji utjecaj na stupanj klijavosti imaju tretmani PAW vodom u čijoj su proizvodnji kao radni plinovi korišteni kisik i dušik, dok je do povećanja koncentracije ukupnih pigmenata došlo u uzorcima tretiranim PAW vodom dobivenom uz upuhivanje zraka. Plazma tretmanom snizuje se pH vrijednost vode što omogućuje da takva voda ima i sterilizacijski učinak. Less

Abstract (english)

This study examines the effect of plasma activated water (PAW) on the germination of barley (Hordeum vulgare cv Golden Promise) after six days of incubation. The physicochemical parameters of the treated water were determined and the effect on the degree of germination and concentration of total pigments were monitored. Water samples were treated with cold plasma at three frequencies: 60, 90 and 120 Hz with the insertion of gasses: argon, air, oxygen and nitrogen. Treatments lasted for ten... More minutes for samples in which argon and air were injected and 20 minutes for samples in which oxygen and nitrogen were inserted. This experiment has shown that the most beneficial effect on the degree of germination is PAW water treatment in which production of oxygen and nitrogen was used as working gas while the increase of concentrations of total pigments occurred in samples treated with PAW water obtained by injection of air. Plasma treatment reduces the pH of water, which allows such water to have a sterilization effect. Less
