Abstract	Sumpor i selen imaju važnu fiziološku ulogu u biljnom metabolizmu te kod mnogih bioloških spojeva, poput npr. aminokiselina, zbog svoje kemijske sličnosti, jedan element može zamijeniti drugi. Tretiranje sjemena pšenice spojevima koji sadrže sumpor ili selen može poboljšati otpornost biljke na različite stresne uvjete okoline. Cilj istraživanja je bio utvrditi utjecaj primiranja sjemena otopinama NaHS, Na2SeO4 i Na2SeO4+NaHS na fiziološka svojstva kod tri sorte pšenične trave uzgajane pri 10, 20 i 30 ℃. Ispitivan je sadržaj vitamina C, prolina, udio suhe tvari i stupanj lipidne peroksidacije. Kod sorte Katarina na sadržaj vitamina C i prolina najznačajnije je utjecao tretman sjemena kombinacijom Na2SeO4 i NaHS. Najviša razina lipidne peroksidacije je utvrđena kod kontrolnih biljaka čije sjeme je primirano u vodi i naklijavano pri 20 ℃. U usporedbi s 10 i 20 ℃, pri 30 ℃ je utvrđen značajno niži sadržaj suhe tvari. Pri 10 ℃ je utvrđen značajno veći sadržaj vitamina C kod sve tri sorte pšenične trave. Utvrđene su značajne razlike u odgovoru na pojedine varijante tretmana što upućuje na to da postoji genetska specifičnost u fiziološkom odgovoru na selen, sumporovodik i temperature uzgoja pšenične trave.
Abstract (english)	Sulphur and selenium have an important physiological role in plant metabolism and in many biological compounds, for example aminoacids, because of the similarity in their chemical structure, one element can replace the other. Treating wheat seeds with compounds that contain sulphur or selenium can improve the plants resistance to a wide range of stressful environmental conditions. The goal of this research was to determine the effect of seed priming with compounds NaHS, Na2SeO4 and Na2SeO4+NaHS on the physiological properties on three cultivars of wheatgrass grown at 10, 20 i 30 ℃. The content of vitamin C, proline, dry matter and the degree of lipid peroxidation was analyzed. Cultivar Katarina showed the greatest effect of the combination of Na2SeO4 and NaHS on vitamin C and proline content. The highest degree of lipid peroxidation was determined in the control plants whose seeds were primed in water and sprouted at 20 ℃. In comparison to 10 and 20 ℃, the highest applied temperature (30 ℃) resulted with a significantly lower dry matter content. At 10 ℃, a significantly higher content of vitamin C was determined in all three cultivars. Significant differences in response to individual treatment variants were determined, which indicates a genetic specificity in the physiological response to selenium, hydrogen sulfide and the growing temperature of wheat grass.
