Expediency of fiber flax seed fractionation to improve their sowing qualities

Abstract

The paper substantiates the expediency of presowing fractionation of fiber flax seeds. The size of the fractions and their influence on the sowing characteristics, chemical and biochemical properties of the seed material for the formation of a monomorphic highly productive cenosis have been established. A direct proportional relationship was established between the volumetric weight of seeds and their mass (R2 = 0,98), germination (R2 = 0,94), sowing suitability (R2 = 0,94) and an inverse relationship with their infection with diseases (R2 = 0,93). A decrease in the volumetric weight of seeds reduces the content of nitrogen and crude protein in the seeds, and increases the content of crude fiber.
