Contents of amino acids in various cultivars of barley (Hordeum vulgare L.)

Abstract

The twenty barley cultivars were grown under nutrition by Nitrogen dose 60 kg ha-1 on field soil (type pseudogley). The grains of barley cultivars were used for study of variability of amino-acid. By qualitative analysis are identified 11 different amino acids. For each of indentified amino acid was used quantitative method to determine their concentration. The total concentration of free amino acids was analyzed for all varieties of barley. The highest total concentration of free amino acids in the analyzed varieties of barley cultivars with Ac Oxbow (11.5%), Sissy (11.3%), Steffi (11.2%), Severa (11.1%), Scarlett (11.0%) and the smallest variety Zaida, Ursa, Seebe, Aren (8.8%) and cultivar Tempera (8.0%). Soil fertility implies the existence of easily accessible nutrients for plants. Out of all the elements absorbed from the soil, the plants need nitrogen in the largest quantities.
