Abstract

Background: Selenium (Se34) is an essential micronutrientfor humans and animals and has growth promoting andantioxidative effects at low concentrations.Methods: Effects of various sodium selenite (Na2SeO3)doses on grain amino acid content of barley cultivars(Bülbül 89 and Çetin 2000) was investigated using ionexchange liquid chromatography.Results: Majority of the amino acids could be altered withSelenium (Se) fertilization. Grain Se content of Bülbül 89(0.175 mg kg−1) and Çetin 2000 (0.171 mg kg−1) were similarand both displayed an increase in proteinogenic, essential,and sulfur amino acids. The response of cultivars was morepronounced for Se accumulation and amino acid contentat mid dose (12.5 mg ha−1). The quantities of proteinogenic,essential and sulfur amino acids increased considerably atthat dose. Se induced increase in nitrogen content mightcause an increase in some of the proteins of grain and consequentlycan alter amino acid composition. An obviousincrease in the limiting amino acids (lysine and threonine)were prominent in response to Se fertilization.Conclusion: Se treatment influence amino acid compositionof barley grains; especially improve the quantity oflimiting amino acids and consequently nutritional valueof the grain.

Özet

Giriş: Selenyum (Se34) insan ve hayvanlar için esansiyel bir mikronütrient olup düşük dozlarda büyümeyi teşvik edici ve antioksidatif etki gösterir. Metod: Çeşitli dozlardaki sodyum selenitin (Na2SeO3) arpa çeşitlerinin (Bülbül 89, Çetin 2000) tane amino asit içeriği üzerindeki etkisi iyon değişimi sıvı kromatografisi ile analiz edilmiştir. Bulgular: Çeşitlerde amino asitlerin çoğunun selenyum (Se) uygulamasına bağlı olarak değişebileceği gösterilmiştir. Bülbül 89 (0.175 mg kg−1) ve Çetin 2000 (0.171 mg kg−1) çeşitlerinde tane Se içeriği birbirine yakın olup her ikiside proteinogenik, esansiyel ve kükürtlü aa içeriğinde artış göstermiştir. Çeşitlerin Se birikimi ve amino asit içeriği bakımından gösterdiği tepki ara dozda (12.5 mg ha−1) daha belirgin olmuştur. Bu dozda proteinogenik, esansiyel ve kükürtlü amino asit miktarı belirgin şekilde artış göstermiştir. Tane azot içeriğindeki Se indüklü artış bazı proteinlerin artışına neden olabilir ve buna bağlı olarakta amino asit bileşimini değiştirebilir. Çeşitlerde sınırlayıcı amino asitlerdeki (lizin ve treonin) bariz artış Se uygulamasına tepki olarak öne çıkmaktadır. Sonuç: Se uygulaması arpa tanesinde amino asit içeriğini etkilemekte olup özellikle sınırlayıcı amino asitlerin miktarını artırmak suretiyle tanede besin değerinin iyileştirilmesine katkı sağlamaktadır.
