“…The prerequisite for the production of high quality foodstuffs is a high quality raw material -grain. The results of studies on oats in Latvia confirmed that grain quality indices can be affected by the weather conditions during the growing season, location and genotypes (Bleidere et al, 2012), meteorological conditions (Zute et al, 2010) and nitrogen management (Brunava et al, 2015). Therefore development of oat cultivars adaptable to changing climatic conditions and capable of ensuring both stable yields and corresponding grain quality from year to year is the most significant task for oat breeders in Latvia.…”

“…'Stendes Emilija', included in this study, is the first local naked oat cultivar registered in Latvia. Other studies showed that grains of naked cultivars have an excellent biochemical composition -high levels of soluble fibres such as betaglucan (Brunava et al, 2015), crude protein (Sterna et al, 2016) and high content of α-tocopherol (Sterna et al, 2014) -traits, determining dietary quality of products.…”

The aim of the research was to quantify 13 macro and trace elements in different oat (Avena sativa L.) genotypes depending on the year of cultivation (2011, 2012 and 2013) and crop management practice (conventional or organic), agronomic practice (different N supply) and evaluate the risks regarding Cd, Pb, Cr, Ni, Cu, Zn and Al concentrations and nutritional aspects regarding K, Na, Ca, Mn, Mg, Fe, Cu, Zn and Cr concentrations in oat grain. Elements Cd, Pb, Cr, Ni and Al were detected by electrothermal atomic absorption spectrometry, and K, Na, Zn, Cu, Ca, Mg, Mn and Fe were analysed by flame atomic absorption spectrometry. Cluster analysis showed that genotype and agronomic / crop management practice play an important role in the concentration of macro and trace elements in oat grain. Statistically different concentrations of elements were noticed for Cr, Ni, Zn, K and Mg among the genotypes: for Mn and Fe in grains, grown conventionally or organically, for Cr, Ni, Zn, K and Mg in hulled and naked grain, and for Cd, Pb, Ni, Cu, Al, K, Na and Mg among the study years. The concentrations of potentially hazardous elements were low: Cd 0.008-0.023, Pb 0.014-0.060, Cr 0.117-1.460, Ni 0.447-1.834, Cu 3.2-4.1 and Zn 22.0-32.3 mg kg-1. Oat products can contribute to the consumption of necessary macro and trace elements, especially of Mn, Mg and Fe: 30.0-49.3, 1166-1486 and 33.5-48.9 mg kg-1 , respectively, as well as Cr and Zn.

Abstract. In this paper, the results obtained from the investigations performed on determination of the content of soluble dietary fibre component β-glucan in different cereals grown by conventional and organic farming method are presented. Because dietary fibre and its components have great importance for human and animal nutrition as well as health benefits, it was a need to investigate the content of β-glucan from cereal domestic origin. Standardized enzymatic-gravimetric method-a mixed-linkage β-glucan assay Megazyme Kit (Megazyme, Ireland) was used for determination of β-glucan content in 27 different cereal samples: barley, oat, rye and wheat, grown at three locations during 2013. The mean values of β-glucan content in cereals conventionally grown ranged from 34.41 ± 1.47 g.kg -1 db with barley, through 23.5 ± 4.52 g.kg -1 db and 15.61 ± 0.36 g.kg -1 db with oat and rye, respectively to 5.60 ± 1.02 g.kg -1 db with wheat. The mean values of β-glucan content in analyzed cereals which were organically grown ranged from 33.28 ± 2.34 g.kg -1 db with barley, 21.3 ± 1.87 g.kg -1 db with oat, 15.81 ± 2.30 g.kg -1 db with rye and to 6.04 ± 0.58 g.kg -1 db with wheat. Compared to the other cereals investigated, barley grown by either conventional or organic farming method proved to have the highest content of β-glucan demonstrating its good perspective in cereal processing and technology, food market and human and animal nutrition. The positive/negative correlations allow indirect evaluation of cereals in breeding work aimed at creation of forms with increased/decreased content of β-glucans in grain.
