Abstract
Abstract Background Selenium (Se 34 ) is an essential micronutrient for humans and animals and has growth promoting and antioxidative effects at low concentrations. Methods Effects of various sodium selenite (Na 2 SeO 3 ) doses on grain amino acid content of barley cultivars (Bülbül 89 and Çetin 2000) was investigated using ion exchange liquid chromatography. Results Majority of the amino acids could be altered with Selenium (Se) fertilization. Grain Se content of Bülbül 89 (0.175 mg kg −1 ) and Çetin 2000 (0.171 mg kg −1 ) were similar and both displayed an increase in proteinogenic, essential, and sulfur amino acids. The response of cultivars was more pronounced for Se accumulation and amino acid content at mid dose (12.5 mg ha −1 ). The quantities of proteinogenic, essential and sulfur amino acids increased considerably at that dose. Se induced increase in nitrogen content might cause an increase in some of the proteins of grain and consequently can alter amino acid composition. An obvious increase in the limiting amino acids (lysine and threonine) were prominent in response to Se fertilization. Conclusion Se treatment influence amino acid composition of barley grains; especially improve the quantity of limiting amino acids and consequently nutritional value of the grain.
