Životna sposobnost i vigor semena različitih inbred linija kukuruza tretiranih neonikotinoidima

The aim of this study was to examine the effects of different neonicotinoid seed treatments on viability and vigour of maize (Zea mays L.) inbred lines. The trial included three maize inbred lines (207 x 312/5 DNS, 7-1 NS, and 312/5 DNS) treated with recommended doses of three commercial formulations of systemic insecticides (Poncho 600-FS, Gaucho 600-FS, and Cruiser 350-FS). Generally, formulation Gaucho 600-FS can be considered the most harmful regarding the impact on the reduction of germination in all tested maize inbred lines. A significant reduction of germination in maize inbred line 7-1 NS was observed after seed treatment with Cruiser 350-FS, using the standard germination test and cold test. A significant increase in seedlings root and shoot growth of maize inbred line 312/5 DNS treated with Poncho 600-FS and Cruiser 350-FS was noted using the cold test.Cilj ovog istraživanja je bio da se ispita uticaj različitih tretmana semena neonikotinoidima na životnu sposobnost i vigor semena inbred (Zea mays L.) linija kukuruza. Eksperimentalni objekti su bile tri različite inbred linije kukuruza (207 x 312/5 DNS, 7-1 NS i 312/5 DNS) tretirane sa tri komercijalne formulacije (Poncho 600-FS, Gaucho 600-FS i Cruiser 350-FS) u preporučenim dozama. Generalno se Gaucho 600-FS može smatrati štetnim pošto utiče na smanjenje klijavosti semena kod svih ispitivanih inbred linija. Značajno smanjenje klijavosti semena inbred linije 7-1 NS primećeno je nakon tretmana sa Cruiser 350-FS kod standarnog testa klijavosti i hladnog testa. Značajan porast korena i nadzemnog dela izdanaka inbred linije 312/5 DNS tretirane formulacijama Poncho 600-FS i Cruiser 350-FS je uočen primenom hladnog testa
