Scientifically based quality concept of seeding seeds of varieties

This article speaks of the need for specific soil and climatic conditions to study in more detail the degree of variability of the properties of seeds and their conjugation. It is especially important to establish the nature of the relationship traditionally taken into account in the selection of linear dimensions and the mass of the seed. It is necessary to correctly distinguish the process of germination associated with qualitative changes in the seed, with the period of germination, i.e. the duration of certain transformations. With a single process of seed development during their sorting (calibration), one controlled parameter is insufficient, which does not allow the selection of biologically more valuable seeds. According to the qualifications of ISTA (International Association for the Control of Seed Quality), the end of the seed germination process in the physiological sense is the appearance of a root (pecking); in the control-seed analysis the development of the root and cotyledons to a state that makes it possible to judge the ability of the seed to produce a healthy plant under favorable conditions; in agronomic the emergence of seedlings.
