Nickel (Ni) Content in the Above-Ground Portions and Kernel of Different Small Grain Cultivars

Abstract

To ensure safe food production, cultivar-specific traits of winter small grains were analysed in terms of mineral nutrition in order to determine differences between small grain (barley, oat and triticale) genotypes in the level of certain heavy metals (Ni). The kernel of mature small grain plants and their vegetative biomass were found to contain quite different levels of Ni, depending on genotype properties and fertilisation systems. Ni content in oat kernel was above toxic levels and cannot be used for safe food production. Barley and triticale samples complied with quality criteria in terms of their Ni levels.

U cilju proizvodnje zdravstveno bezbedne hrane ispitivane su sortne specifičnosti ozimih strnih žita, u odnosu na mineralnu ishranu, kako bi se ustanovile međusobne razlike genotipova strnih žita (ječma, ovsa i tritikalea), u odnosu na zastupljenost pojedinih teških metala (Ni). Konstatovano je da zrno zrelih biljaka strnih žita i vegetativna masa imaju veoma različite sadržaje Ni, u zavisnosti od osobina genotipova i sistema đubrenja. Sadržaj Ni u zrnu ovsa, bio je iznad toksičnih sadržaja i ne može se koristiti za proizvodnju zdravstveno bezbedne hrane. Sa aspekta sadržaja Ni u uzorcima ječma i tritikalea, možemo zaključiti da ispitivani uzorci zadovoljavaju kriterijume kvaliteta.
