The aim of the research is to clarify the physiological and biochemical processes in the plant organism that occur in the optimal and stressful conditions, as well as to search for anthropogenic methods of their manifestation in connection with the protein content in grain of wheat varieties of different origin in the conditions of the Forest-Steppe Ukraine. The impact of temperature factor and the moistening mode of the period of winter wheat seed formation and ripening (Triticum aestivum L.) has been studied. The impact of varieties of Ukrainian and foreign plant breeding on the protein content in grain of the obtained offspring (reproduction yield) has been studied too. The ways to eliminate the influence of weather conditions on the protein content in grain and on the bases of sowing of different seed fractions have been searched.
