ENERGY CONSIDERATIONS FOR A METHOD OF ASSESSING THE VIABILITY OF SEEDS

Methods for determining the viability of biological objects are based on the identification of differences in the response of objects to the effects of external environmental parameters. To analyze the existing methods for determining the viability of seeds and providing prerequisites for the development of a rapid method for estimating this indicator, use was made of the fundamentals of the analysis of material-energy transformations of material systems in the course of biotechnological processes occurring in them. The most general approach to the analysis of biotechnological processes occurring during storage and subsequent cyclic activation is the regularities of multivariate energy transformations, i.e. this is actually a thermodynamic approach. On this basis, the grain biosystem was compared with the following systems: an isolated system; an energy
conservative system; a dynamically stationary system; and a dynamically quasi-stationary system. The authors have formalized energy conditions, in which biosystems jump into other qualitative states under the influence of external factors. The viability of the examined grain is determined according to the form of the transient process.
