Abstract
The objective of this study was to determine whether the kinetics of germination of seeds stimulated by multi- periodic and
chaotic electromagnetic fields could be described using the modified Malthus-Verhulst equation. The electrical circuits used for
magnetization could generate signals of period 1, -2, and -4 as well as chaotic ones. The study was carried out on two varieties of
beans (V1 and V2) whose seeds were stimulated for 3 and 5 minutes respectively with electromagnetic fields of periodic properties
mentioned above. A group of unexposed seeds served as the control for comparative analysis. The curves were plotted for the
experimental data by minimizing the square sum of the differences between the experimental data and the mathematical model.
We found that the experimental data fit well with the model, but only on the condition that all the seeds submitted to the same
experimental treatment do not emerge at the same time. Analysis of variance (ANOVA) showed a significant difference in germination
rates as well as the difference in lengths for various treatments (P < 0.05). The conclusion that the effect of electromagnetic signals
on the development of these plants depends both on the variety of seeds and the duration of stimulation, as well as on the periodicity
of the signal could be drawn.
