Seed qualities variation of spring wheat grain depending on its alignment

Choosing the optimal seed size plays a significant role in obtaining a high grain yield with excellent technological, seed and yield qualities. The obtained experimental material will allow agricultural enterprises to form batches of grain with high food and seed qualities, depending on the grain alignment. The purpose of this work was to assess the impact of seed size on seed quality indicators of soft spring wheat. The role of alignment in the formation of germination energy, growth strength and germination of soft spring wheat seeds was studied. As a result, it was found that the germination energy of spring wheat seeds reached a maximum in fractions of size from 2.5 mm to 3.0 mm and from 3.0 mm and above – 93 %. The variation of the indicator was low 8 %. The strength of seed growth was subject to a high and medium degree of variation in fractions (18-43 %). Not one of the fractions could form seeds with a growth strength of 60 % consistently. Seed germination was close to 100 % for grains with a size of more than 2.5 mm and reached a maximum for seeds with a thickness of more than 3.0 mm. The difference between the germination of the smallest fraction and the other two ones was more than 40 %, and its average value was at the level of 56 %.
