dc.description.abstract | Wheat grains is often contaminated by initial population in the field, so that grain's surface parts contain the highest concentration of harmful matters. For this reason, surface treatment of wheat grains has a great importance. Micro and macro - elements in small and large particles produced by surface treatment of wheat grains of Novosadska rana 5 variety, harvested in 2002, was studied. The surface treatment was carried out using a special device constructed at the Faculty of Agriculture, Zemun, Serbia. First of all, the impurities from the kernel surface and the part of the very shell were removed by dry scoring for 2 minutes, small and large particles were wet mineralized and finally fifteen micro and macro - elements were determined by AAS ( Unicam SP 90). The results obtained were statistically analyzed using the StatistikaR ver. 5.0 (StatSoft Co., USA). The t - test, linear regression and correlation were performed. Differences in contents of Na, K Ca, Mg, Pb, Cu, Ni, Mn, Zn, Cd, Cr and Se in small and large particles were found to be statistically significant at the level of 0,05, while in the case of Fe no difference was observed. The statistical analysis was not performed in the case Hg and As, because they were present in traces. | en |
dc.description.abstract | Zrno pšenice često biva kontanimirano inicijalnom populacijom u polju, što dovodi do toga da površinski delovi pšeničnog zrna sadrže najveću koncentraciju štetnih materijala. U radu su izvršena ispitivanja mikro i makro elemenata u sitnom i krupnom prelazu posle površinske obrade zrna pšenice visokokvalitetne sorte Novosadska rana 5, berba 2002. godine. Najpre je postupkom suvog ribanja sa površine zrna odstranjena nečistoća i deo samog omotača a zatim su nakon mokrog spaljivanja, vršena određivanja sadržaja mikro i makro elemenata u krupnom i sitnom prelazu pomoću atomske apsorpcione spektrofotometrijske analize, uz upotrebu šuplje katodne lampe kao izvora zračenja, na AAS Unicam SP 90. Dobijeni rezultati statistički su obrađeni primenom softera StatistikaR ver. 5.0 (StatSoft Co., USA). | sr |
