How to Manage the Effectiveness of Presowing Treatment of Seeds

Abstract

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.
