Abstract	Cilj istraživanja bio je utvrditi optimalne elektromagnetske uvjete za rast i razvoj biljaka na nivou klijavosti sjemena. Sjemenke poljoprivredne kulture suncokreta (Helianthus annuus L.) tretirane su neionizirajućim elektromagnetskim zračenjem u tri varijante u ovisnosti o tri fizikalne veličine. Korištena frekvencija zračenja nalazi se u spektru od 0,8 do 8 GHz uz trajanje zračenja od 30 ili 60 minuta te jakosti polja od 0 do -12 dBm. U sve tri varijante prisutna je statistički značajna razlika kod promatranih karakteristika klijanaca uspoređenih s kontrolnim uzorkom. Najveći broj statistički značajnih razlika kod promatranih parametara nalazi se uz frekvenciju 1 GHz, pri kojoj je u četvrtom danu eksperimenta utvrđen stimulativni utjecaj zračenja visokim brojem klijanaca s razvijenim sekundarnim korijenjem, smanjenjem broja deformiranih klijanaca te povećanjem standardne klijavosti. Osim efekta zagrijavanja, utjecaj elektromagnetskog zračenja visokih frekvencija očituje se i kroz povećanje konduktivosti i pojačanog djelovanja enzima unutar biološke tvari, dakle parametara koji u ovom istraživanju nisu utvrđivani, te su potrebna daljnja istraživanja u svrhu određivanja optimalne količine stresa elektromagnetskim zračenjem na klijance poljoprivredne kulture.
Abstract (english)	The aim of the study was to determine the optimal electromagnetic conditions for plant growth and development at the level of seed germination. In the study, seed material of sunflower (Helianthus annuus L.) was treated with non-ionizing electromagnetic radiation in three variants depending on the three physical quantities. The radiation frequency used is in the spectrum from 0.8 to 8 GHz with a radiation duration of 30 or 60 minutes and a field strength of 0 to -12 dBm. In all three variants, there was a statistically significant difference in the observed characteristics of seedlings compared with the control sample. The largest number of statistically significant differences in the observed parameters is found with the radiation frequency of 1 GHz where on the fourth day of the experiment the stimulating effect of radiation with a high number of seedlings with developed secondary roots, reduction of deformed seedlings and increased of standard germination was determined. In addition to the warming effect, the effect of high frequency 23 electromagnetic field is manifested through increased conductivity and enhanced enzyme activity within biological matter, parameters that were not determined in this study. Therefore, further research is needed to determine the optimal amount of electromagnetic radiation stress on seedlings.
