Sažetak

Cilj rada bio je da se ispita optimalno vreme potapanja semena soje i njegov efekat u uslovima sonog stresa. Testiranje je sprovedeno u Institutu za ratarstvo i povrtarstvo u Novom Sadu na semenu sorte Galina. Optimalno vreme utvrđeno je potapanjem semena u prajmere: KNO3 (1%), H2O2 (0,1%) i H2O u trajanju od 6 h, 12 h, 18 h i 24 h. Posle sušenja do prvobitne vlage, seme je stavljeno na naklijavanje, a nakon 8 dana utvrđena je klijavost. U drugom ogledu seme je potapano u prajmere: KNO3 (1%), H2O2 (0,1%) i H2O, a nakon toga ispitivan je njihov efekat na energiju klijanja i klijavost semena u uslovima simulirane zaslanjenosti. Simulirane uslove zaslanjenosti predstavljale su podloge za naklijavanje kojima je dodat rastvor NaCl u različitim koncentracijama (0, 50, 100, 150, 200 mM). Rezultati istraživanja su pokazali da je najbolje šestočasovno potapanje semena kod svih prajmera. Sa povećanjem vremena potapanja linearno se smanjuje procenat klijavosti semena. Istraživanja su pokazala i da potapanje semena predstavlja povoljnu tehniku za smanjenje negativnog uticaja NaCl na energiju klijanja i klijavost semena soje, a najbolji efekat ostvaren je upotrebom KNO3.
