“…Отмечено, что селен участвует в синтезе трикарбоновых кислот, в реакциях образования хлорофилла, а также в метаболизме высокомолекулярных жирных кислот. Вместе с молибденом и железом или один в качестве кофактора он присутствует в ряде окислительно-восстановительных ферментов [11,12]. В России и мире накоплен большой опыт выращи- Опыт включал следующие варианты: 1 -контроль 1 (сухие семена), 2 -контроль 2 (замачивание семян в дистиллированной воде), 3 -инкрустация семян НП Se (полусухое протравливание), 4 -замачивание семян за 30 мин до посева в растворе НП Se из расчета 0,1 г/га.…”

Peculiarities of yield formation of maize variety Obskiy 140 the cultivation of it with the use of selenium nanoparticles of an optimum concentration. The experiment was carried out in soil culture in 3-fold repetition. Agrochemical parameters of soil: рН 6,2; the КСl humus of 2.6%; P O 204 mg/kg and K O 219 mg/kg soil. Four variants of the experiment were developed: control 1 (dry seeds), 2 5 2 control 2 (soaking seeds in water), NP Se inlay (semi-dry etching) and NP Se soaking (30 minutes before sowing at the rate of 0,1 g/ha of NP selenium). In the experiments, NP Se containing 3,7 mg of nanopreparation Se in 1 liter of water was used. The positive effect of selenium nanoparticles on the growth processes of maize seeds: germination, germination energy, growth force is shown. Se NP seed treatment increases germination energy by 6,90 and 9,13%, laboratory germination by 4,67 and 8,34%, growth strength by 26,32 and 31,05%, respectively, control 2 (soaking in water) and control 1 (dry change). Under adverse conditions, the use of selenium nanoparticles increases the growth of plants in height. Positive effect on the accumulation of starch in corn grains inlay NP Se, and soaking in this drug increases the content of protein fractions. The greatest increase in the yield of dry corn phytomass provides soaking seeds with selenium nanoparticles, which is caused by an increase in the yield of green corn mass.

Investigation of the antioxidant activity (AOA) induction by selenium compounds (Na2SeO3, diacetophenonyl selenide (DAPS-25), L-selenocystine) in various organisms is interesting as a protection from stress induced cell membranes damages. A comparative analysis of the antioxidant activity of 23 amino acids was performed by coulometric titration with electrogenerated bromine and iodine. The activity decreases in the order: cystine tryptophan selenocystine tyrosine 3,3'-dimethyl-L-selenocystine methionine. Only amino acids with sulfhydryl and selenol groups as more active reductants can interact with the electrogenerated iodine: cysteine selenocysteine threo-3-methyl-L-selenocysteine. Probably the correction of the antioxidant status at the amino acids level is based on the sulfhydryl and selenol groups in radicals. In case they are not enough, cystine, selenocystin, tryptophan, tyrosine, and methionine will act as scavenger-reductants. It was found that selenium compounds dose-dependently induce the total antioxidant activity of the A. niger mycelium and affect indicators of the antioxidant status (amino acid composition and catalase activity), which in turn stimulates the biomass accumulation. DAPS-25 and sodium selenite treatment at the high doses (0.025 mg Se/L) caused the greatest effect on the total AOA induction (3.4–5.5 times). Lower concentrations (0.0025–0.00025 mg Se/L) had a lesser effect (25.8–41.7%). Activity in samples with L-selenocystin increased by 1.6–43.3%. It is noted that the iodine antioxidant activity in the mycelium was generally lower than the bromine one.
