abstract = "Drought is one of the most important factors limiting the successful production of cultivated plants. One of the most sensitive stage to the water deficit in plants is seed germination. There are various methods of pre-sowing treatments that aim to reduce the negative impact of drought stress and improve seed germination. One of them is priming seeds. The aim of this experiment was to examine the effect of priming seeds in solutions - KNO3 (1%), ascorbic acid - AsA (100 mgl-1) and potassium chloride KCl (1%) on the reduction of the negative effect of drought stress. The effect of drought stress was simulated using different concentrations of PEG 6000 (0 (control), -0.30, -0.51, -0.80 MPa). The results of the research showed that with the increase of water deficiency, the effect of priming seeds is greater. At the water potential of the solution of -0.30 MPa, germination energy and seed germination increased on average by 6.77% and 5.08%, while at the water potential of the solution of -0.80 MPa, the increase was 19.28% and 16.75%, respectively. Also, priming seeds significantly reduced the intensity of lipid peroxidation and the content of free proline. From all the above, it can be concluded that priming of seeds is a method that can serve to improve the germination of soybean seeds in conditions of drought stress., Suša je jedan od najvažnijih faktora koji ograničava uspešnu proizvodnju kulturnih biljaka. Jedna od najosetljivijih faza na nedostatak vode kod biljaka je klijanje semena. Postoje razne metode odnosno predsetveni tretmani koj imaju cilj da smanje negativan uticaj nedostatka vode i poboljšaju klijanje semena. Jedan od njih je potapanje semena. Cilj ovog eksperimenta bio je da se ispita uticaj potapanja semena u rastvore - KNO3 (1%), askorbinsku kiselinu - AsA (100mgl-1) i kalijum hlorid KCl (1%) na smanjenje negativnog uticaja suše. Dejstvo suše simulirano je primenom različitih koncentracija PEG-a 6000 (0 (kontrola), -0,30, -0,51, -0,80 MPa). Rezultati istraživanja su pokazali da je sa povećanjem nedostatka vode efekat potapanja semena veći. Pri vodnom potencijalu rastvora od -0,30 MPa enerija klijanja i klijavost semena povećani su, u proseku, za 6,77% odnosno 5,08% dok je pri vodnom potencijalu rastvora od - 0,80 MPa povećanje iznosilo 19,28% odnosno 16,75%. Takođe, potapanje semena značajno je smanjilo intenzitet lipidne peroksiacije i sadržaj slobodnog prolina. Iz svega navedenog može se zaključiti da je potapanje semena metod koji može da poboljša klijanje semena soje u uslovima suše.",
