THE STUDY OF THE ACCUMULATION OF GLUTENIN UNDER THE ACTION OF LONG-TERM FERTILIZATION

Alina Laura Agapie

Abstract

This paper presents the effect of fertilizers with nitrogen and phosphorus, applied both unilaterally and in different combinations, on the quality of wheat grains during the period 2014-2017. In this regard, the research was carried out on Ciprian wheat variety, created at SCDA Lovrin, in a long-term experience with fertilizers, founded in 1967. In addition to genetics, the climatic factor and the technological factor play a fundamental role for obtaining superior quality productions for winter wheat, to the deepest levels. The glutenin extraction was performed by the Lab on a Chip method. The study of the average glutenin accumulation results demonstrates the importance of the combined application of the two types of fertilizer. If we report the average results obtained during the three years of vegetation to the total content of glutenin it results a significant increase of its values (between 23.92 g and 25.89 g) in all fertilized variants compared to the unfertilized control variant with an average content of glutenin of only 11.01 g / 100 g flour. The fertilizer combinations studied influences distinctly significantly positive and the accumulation of HMW glutenin subunits.
