Ecological and physiological features of the phytomass of amaranth in introduction in the Republic of Tatarstan

The dynamics of the distribution of soluble forms of the green mass protein of two types of amaranth in ontogenesis was studied. The influence of weather conditions during vegetation periods with the introduction in the Republic of Tatarstan on the fractional and amino acid structure of amaranth green mass protein is analyzed. When amaranth is cultivated under new conditions, it is revealed that the proteins of the phytomass A. cruentus and A. Mantegazzianus Passerini mainly accumulate readily soluble fractions (from 60 to 80%) with a high content of irreplaceable amino acids. The species specificity of the reaction of the protein synthesizing system of amaranth leaves on the influence of environmental factors in A. cruentus is manifested in a noticeable decrease in the proportion of easily soluble protein fractions in ontogenesis and an increase in the proportion of soluble proteins with SCC 0.5. Ecological and physiological changes in the fractional composition of proteins in A. Mantegazzianus Passerini are less significant. The redistributions that occur in the complex of soluble proteins and the amino acid pool at different meteorological conditions do not have a significant effect on the biological value of amaranth proteins, but are part of its adaptive mechanisms of environmental sustainability.
