“…Using protease XIV and sonication assisted hydrolysis and anion exchange chromatography techniques, SeMet and Se (VI) were detected and identified in durum and bread wheat grains, and SeMet, as the principal species, accounted for 54% to 95% of the total Se content depending on the cultivars and fertilization (Galinha et al., 2015). SeMet was the only soluble Se species identified in Tartary buckwheat ( Fagopyrum tataricum ) and hybrid buckwheat ( F. hybridum ) after protease XIV hydrolysis and ion exchange chromatography, and it accounted for approximately 35% of the total Se content in grain (Golob et al., 2016). Notably, XANES spectra showed that the Se of wheat grain from a seleniferous area (Punjab, India) existed in the forms of SeMeCys (∼70%) and SeCys (∼30%), with no inorganic species detected (Eiche et al., 2015).…”

Selenium (Se) is a trace mineral micronutrient essential for human health. The diet is the main source of Se intake. Se‐deficiency is associated with many diseases, and up to 1 billion people suffer from Se‐deficiency worldwide. Cereals are considered a good choice for Se intake due to their daily consumption as staple foods. Much attention has been paid to the contents of Se in cereals and other foods. Se‐enriched cereals are produced by biofortification. Notably, the gap between the nutritional and toxic levels of Se is fairly narrow. The chemical structures of Se compounds, rather than their total contents, contribute to the bioavailability, bioactivity, and toxicity of Se. Organic Se species show better bioavailability, higher nutritional value, and less toxicity than inorganic species. In this paper, we reviewed the total content of Se in cereals, Se speciation methods, and the biological effects of Se species on human health. Selenomethionine (SeMet) is generally the most prevalent and important Se species in cereal grains. In conclusion, Se species should be considered in addition to the total Se content when evaluating the nutritional and toxic values of foods such as cereals.

“…All that indicated that hybrid buckwheat had higher photosynthetic activity. Higher ETS activity in Se treated hybrid in comparison to Se treated Tartary buckwheat observed also Golob et al 2016. On the other hand, Tartary buckwheat had higher content of anthocyanins and UV-B and UV-A absorbing substances comparing to hybrid buckwheat (Fig.…”

“…It also has relatively high crude fiber content, and even more rutin and other phenolic compounds than common buckwheat (Fabjan et al 2003). Hybrid buckwheat (Fagopyrum hybridum) is a new buckwheat taxon that was recently obtained by the interspecific crossing of Fagopyrum tataricum (4x = 32) × Fagopyrum giganteum (Fesenko and Fesenko 2010), although little is known about its properties (Golob et al 2016, Golob et al 2018.…”

The impact of selenium (Se) addition and UV radiation on Tartary buckwheat and hybrid buckwheat were studied. Both buckwheat species grew outdoors at the experimental field of the Biotechnical Faculty in Ljubljana. They were exposed to four different treatments regarding the UV radiation (ambient or reduced) and added Se (naturally accessible or foliary treated with Na selenate in concentration 10 mg Se L-1). The content of pigments (chlorophyll a and b, carotenoids, anthocyanins) and UV absorbing compounds, transpiration rate, photochemical efficiency of photosystem II (PS) II and respiratory potential were measured. At the end of experiment we determined the biomass of different plant parts. The results showed that irrespective of the buckwheat species the added Se lowered the content of chlorophyll a and carotenoids, while it increased the effective quantum yield of PS II and transpiration rate. UV radiation reduced the content of anthocyanins only. Se and UV-B radiation as independent factors exerted no impact on buckwheat yield. Hybrid buckwheat had a higher physiological activity than the Tartary buckwheat yet a smaller biomass of plant parts, including reduced yield. Ambient UV radiation had a slightly negative impact on hybrid buckwheat while it had no noticeable negative impact on Tartary buckwheat. The Se treated Tartary and hybrid buckwheat were suitable for human andanimal diet regarding to Se concentrations in leaves and grains.

“…Essentiality of Se and I for plants is still under debate. However, it has been evidenced that Se has many positive effects on plants, capable of accumulating this element (Golob et al 2016). Recently there were some reports about combined effects of Se and I on plants (Zhu et al 2004, Smoleń et al 2014, 2016, Germ et al 2015, Osmić et al 2017, Jerše et al 2017.…”

Fagopyrin and rutin concentration in seeds of common buckwheat plants treated with Se and IVery little data about impact of simultaneous addition of selenium and iodine on plants exists. Plants of common buckwheat Fagopyrum esculentum Moench. were grown outdoors and were foliarly treated at the beginning of the flowering with different forms of Se (selenite, selenate) and I (iodide, iodate) and their combinations. Plants were harvested and seeds were collected and grounded, and the concentrations of fagopyrin and rutin were determined. Nor Se, nor I, alone or their combination had an influence on the concentration of fagopyrin. Selenium, iodine and their combination affected the amount of rutin in common buckwheat grain.Key words: fagopyrin, rutin, common buckwheat, seeds, Se, I IZVLEČEK Vsebnost fagopirina in rutina v semenih navadne ajde tretirane s selenom in jodomZelo malo je znanega o sočasnem vplivu elementov selena in joda na rastline. Rastline navadne ajde (Fagopyrum esculentum Moench.) gojene na prostem, smo v začetku cvetenja tretirali z raztopinami selena (selenit, selenat) in joda (jodit, jodat) ter njihovimi kombinacijami. Zrnje tretiranih rastlin je bilo zmleto in izmerili smo koncentracije fagopirina in rutina. Na koncentracijo fagopirina v zrnju ni vplivalo niti tretiranje rastlin s selenom niti z jodom, pa tudi ne kombinacija obeh elementov. Na koncentracijo rutina v zrnju pa so značilno vplivala tako posamična tretiranja z raztopinami obeh elementov kot tudi kombinirano tretiranje.
