Sažetak
U današnje vreme, različite tehnike prajminga semena, kao što su hidroprajming i prajming semena cinkom, koriste se u cilju poboljšanja useva. Značaj tehnika prajminga u postizanju bolje klijavosti semena, poboljšanju useva i postizanju visokog prinosa kukuruza dobro je dokumentovana. Međutim, još uvek nedostaju rezultati o uticaju prajminga semena vodom i cinkom na kvalitet i životnu sposobnost semena, s obzirom da se seme kukuruza može čuvati u skladištu duži niz godina bez značajnog smanjenja klijavosti. Ovo istraživanje je sprovedeno sa ciljem da se ispita uticaj prajminga semena vodom i cinkom na kvalitet i životnu sposobnost semena kukuruza. Za procenu odgovora četiri hibrida kukuruza na prajming semena vodom i 4mM rastvorom cink-sulfata, seme je nakon prajminga podvrgnuto laboratorijskim testovima, testu klijavosti, hladnom testu i testu ubrzanog starenja. Oba tretmana prajminga semena su uticala na povećanje kvaliteta semena kukuruza, ali blagotvorni efekat prajminga semena cinkom se ispoljio u većem stepenu od hidroprajminga u stresnim uslovima hladnog testa i testa ubrzanog starenja. Negativni efekti hidroprajminga na životnu sposobnost semena hibrida NS 4023 ukazuju na moguće ograničenje za odloženu setvu semena kukuruza nakon prajminga.
