Abstract	Klimatske promjene i abiotski stresovi sve su češći problemi u poljoprivrednoj proizvodnji koji za posljedicu imaju smanjenje dostupne hrane za sve veće svjetsko stanovništvo. Jedan od najčešćih abiotskih stresova je suša koja negativno utječe na biljke mijenjajući morfološke, fiziološke i metaboličke procese. Stoga se novim oplemenjivačkim programima, predsjetvenim tretmanima i drugim postupcima pokušava smanjiti njezin utjecaj na biljke. Cilj ovog rada je bio utvrditi utjecaj predsjetvog tretmana sjemena pšenice s različitim koncetracijama prolina (0, 15 i 25 mM) na klijavost sjemena, rani porast mladih izdanaka, morfološka svojstva te kemijska svojstva (sadržaj prolina, enzimatsku aktivnost superoksid dismutaze i peroksidaze) biljaka u suši. Korištenjem otopina različitog osmotskog potencijala (0, -0,5 i -1,0 MPa) inducirana je suša na šest različitih sorata pšenice (Bc1, Bc2, Bc2, Os1, Os2, Os3). Temeljem provedenih analiza utvrđeno je da je predsjetveni tretman prolinom od 15 mM imao pozitivan učinak na duljinu stablijke, svježu i suhu masu nadzemnog dijela te na smanjenu aktivnost superoksid dismutaze (SOD) i peroksidaze (POX).
Abstract (english)	Climate change and abiotic stresses are increasingly common problems in agricultural production, reducing available food for the ever-increasing world population. Drought is one of the most common abiotic stresses, which negatively affects plants by changing morphological, physiological and metabolic processes. Therefore, new breeding programs, seed priming treatments and other procedures are used to reduce its impact on plants. The aim of this work was to determine the influence of seed priming treatment in wheatwith different concentrations of proline (0, 15 and 25 mM) on seed germination, early growth of young shoots, morphological properties and chemical properties (proline content, enzymatic activity superoxide dismutase and peroxidase) of plants under drought. By using solutions of three different concentrations of different osmotic potential of PEG (0, -0.5 MPa and -1.0 MPa), drought was induced in six different varieties of wheat (Bc1, Bc2, Bc2, Os1, Os2, Os3).Based on the analysis, it was determined that the seed priming treatment with 15 mM proline positively affected stem length, fresh and dry weights of shoots, and the reduced activity of superoxide dismutase (SOD) and peroxidase (POX).
