Effect of new biologies on winter wheat structure and technological properties

The paper discusses the scientific aspects towards new biologies based on the natural cells components for winter wheat curing, aimed at increasing wheat yield as well as the plant survival rate under adverse winter factors. Experimental data revealing the effect of new biologies on the technological properties of grain are presented. Biologies based on bean lectins and buckwheat bioflavonoids have a significant impact on shaping the yield structure elements. Thus, the spike grain content according to the experimental results has increased on average by 7.71%, spike productivity by 11%, weight of 1000 grains by 3.3%. The highest yield of winter wheat was obtained from the Leonida cultivar by using the biologies containing bean lectins and buckwheat bioflavonoids - 8.67 t/ha, the maximum yield increase for the hard cultivar 'Kristella' amounted to 0.87 t/ha or 33%. Biologies significantly improve the quality characteristics of winter wheat, increasing the gluten content from 5 to 22%, and changing the IDK indicators by 11 - 18 units. The experimental material opens up the prospects to conduct further research in the field of winter resistance of plants under biologies influence.
