Content of prolin and essential amino acids in spring wheat grain in dry conditions

The article presents the results of the analysis of amino acid composition of grain of spring soft and durum wheat varieties by the amount of proline and essential amino acids under conditions of favorable and dry years in terms of weather factors. An increase in the amount of proline was established under conditions of temperature stress and a lack of moisture in soil, it allows us to consider this fact as an index of resistance to unfavorable environmental factors. The amount of essential amino acids depended on weather and technological factors. The content of the amino acid proline in spring wheat grain should be considered as a signaling function for stressful vegetation conditions. The content of essential amino acids in spring wheat grain increases in favorable years and against the background of moldboard plowing.
