Abstract
Description
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. Research
methods: field (studying the influence of growing conditions on grain quality), laboratory
(determination of protein content), correlation-regression (establishing connection between
factors), statistical method (to confirm the difference between variants). According to the results
of the first stage of research, the dependence has been established: sowing with seed, grown in
the arid conditions, allows obtaining offspring with high protein content, and vice versa. This is
confirmed by the strong correlation both for winter wheat variety. At the second stage of research
it has been determined that sowing with fine seed raises the yield protein content in grain, and
protein yield without additional costs, but using seed, formed in the arid conditions.
