Variants of seed response to external disturbances were studied to determine the principles that should be followed during pre-sowing treatment. The approach that involves analysis of seeds' adaptive response has been applied. The basic organizational rules have been specified for external disturbance application to seeds. The use of informational method for studying the biological response of seeds on external actions made it possible to find the rules that have to be followed when pre-sawing treatment is performed with the use of electrophysical excitation. The essence of these rules is that the following sequence of operations shall be carried out in the process of pre-sowing treatment: to define the lowest energy level of external disturbance corresponding to the seed's sensitivity threshold, to organize cyclic action of external factors on seeds, to vary the amplitude of external factor within cycles, to vary the mode of external disturbance. The field experiments were carried out for several years, during which the pre-sowing treatment of seeds was determined.

Grain is a biological object, with all specific responses to external actions, that reside in this category. To define principles that are needed for pre-sowing seed treatment, possible seed responses to external actions were examined. For this, the analysis of the seed’s adaptive response was used as an approach. Main rules to organize seeds stimulus have been established. Use of an informational approach for analysis of bio-logical seed response on external action allowed to find utilizing rules for electrophysical stimulation during a pre-sowing treatment. The idea behind them is to use the following sequence of operations at the pre-sawing seeds treatment: determine the lowest external action energetic at which grains response; organize cyclical action of external factor on seeds; change of action amplitude in each cycle; change of external action type. Field experiments have been conducted for several years, during which were determined operational modes of aerated grain bin electrical equipment, when used for pre-sowing seed treatment.
