“…Se application significantly increased wheat grain yield at regreening-jointing, jointing-heading, and heading-blooming stages, however, yield was not significantly affected by Se application at blooming-filling stage (Chu et al 2013). A positive effect of 5 g Se/ha for foliar spray on grain yield of common buckwheat was reported (Jiang et al 2015). Selenium at low concentrations acts as a growth stimulant whereas at high concentrations, it reduces root elongation and biomass production of wheat plants (Guerrero et al 2014).…”

Selenium (Se) is one of the elements that determine the normal functioning of an organism; it has antioxidant properties and protects the organism against the actions of free radicals and carcinogenic factors. Selenium is an element that fulfils an important physiological function (Kieliszek and Blažejak 2013), but apart from all the elements, selenium has one of the narrowest range between dietary deficiency (< 40 µg/day) and toxic levels (> 400 µg/day) (Fordyce 2007).While there is no evidence of Se need for higher plants, several reports show that when Se added at low concentrations, it exerts beneficial effects on plant growth. Se may act as quasi-essential micronutrient through altering different physiological and biochemical traits; thus, plants vary considerably in their physiological and biochemical response to Se (El-Ramady et al. 2016).During the last decade, studies related with strategies for Se biofortification in food plants for human nutrition have increased significantly because this metalloid is incorporated into human metabolism mainly as a constituent of food plants (Mora et al. 2015). Biofortification is defined as the process of increasing the bioavailable concentrations of essential elements in the edible portions of cultivated plants through agricultural management (fertilization) or genetic improvement (White and Brodlay 2005).Plant-derived foodstuffs, namely cereals, are the major dietary sources of Se in most countries throughout the world, even if Se contents are strongly dependent upon the corresponding levels in cereal-growing soils. Therefore, wheat is one of the staple crops that appears as an obvious candidate for Se biofortification, considering its Possibility of selenium biofortification of winter wheat grain

“…According to Jiang et al [2015], Se accumulation in common buckwheat was closely associated with the application rate of Se, similarly in case of Germ et al [2013] the increase in Se concentrations in the grain of the double fortified plants was 6-fold greater in comparison to the Se-only bio-fortified plants. According to Poblaciones et al [2013] the difference in concentration between selenite and selenate was more evident as the dose increases.…”

The presented paper deals with monitoring of the ways of selenium (Se) content increase by foliar biofortification with inorganic Se in two varieties of garden pea Pisum sativum L. (Premium, Ambassador) in the conditions of south Slovakia in 2014-2015. The results of experiments show that treatment of plants with two doses of Se concentration (50 g and 100 g Se ha -1 in the form of a sodium selenate anhydrous solution) at the flowering stage significantly increased the total Se content in the seeds of both varieties. Following the results by the consumption of 25 g of dried seeds of peas or 100 g of fresh pea seeds after the biofortification with 100 g Se ha -1 a recommended daily dose of Se in humans may be covered. The significantly positive influence of Se application on the total polyphenols content (TPC) has been confirmed in the both varieties after application of dosage in 100 g Se ha -1 (52% and 33%). A significant increase in the average value of total antioxidant capacity (TAC by DPPH method) in garden pea var. Ambassador was observed after the application of both doses of Se, in case of Premium variety only after application with a 100 g Se ha -1 . Significantly increasing level of TAC by PCL (photochemiluminescence) method was found out only in case of var. Premium.

“…It confirms that sepsis can cause significant liver damage. EPO is an endocrine hormone with anti-inflammatory, antioxidant, anti-apoptotic effects [11][12], and in order to further clarify EPO value for the treatment of acute liver injury induced by sepsis, serum liver damage molecule level change in EPO group was analyzed in the study, and the results showed that serum ALT and AST levels of EPO group were significantly lower than those of CLP group. It is confirms that the EPO has a protective effect on liver function injury caused by sepsis.…”
