“…On the other hand, seeking to contrast this behaviour with others obtained with magnetically treated maize, in the literature it is found that this type of seed has been studied in different varieties for which there was an increase in response to the attack of a pathogen, when the seeds were treated with a electromagnetic field at 60 (Zepeda et al, 2014) length and mass of the root and plant (Aladjadjiyan, 2002;Vashisth & Nagarajan, 2009), vigour indexes (Kataria, Baghel, & Guruprasad, 2015;Vashisth & Nagarajan, 2009;Isaac, Hernández, Domínguez & Cruz, 2011) and establishment (Zepeda et al, 2010). Variables that express effects on germination improvement are reported in: G max between 10% and 16% (Hernandez et al, 2009;Dominguez et al, 2010;Zepeda et al, 2011;Isaac, Hernández, Domínguez,, & Cruz, 2011); V Ger (Dominguez et al, 2010;Shine et al, 2017;Zepeda et al, 2010); MGT and the time to germinate 10%, 25%, and 75% of the seeds have presented significant decrease up to 21% for the MGT (Florez, Carbonell, & Martínez, 2007;Martinez, Florez, & Carbonell, 2017) regarding the control.…”

The effect of homogeneous static magnetic stimulation on Zea mays L. (maize) seeds and its potential utility as a tool in biotechnological development for the improvement of maize seeds was studied. The values of magnetic flux density that influenced the biological development of some plant species of the Poaceae family were determined from a literature review. ICA V-305 variety corn seeds were exposed to seven values of magnetic flux density between 50.0 mT and 250.0 mT, with homogeneity of 98.4% and at (1.0, 3.0, 5.0 and 7.0) min exposure times. The mean germination time (MGT), index of germination speed (VGer) and germination rate (Gmax) were evaluated as responses. The magnetic flux density of 50.0 mT with a one-minute exposure time recorded the largest reduction (12.4%) in the MGT while the germination rate for the same treatment increased by 17.4% with respect to the control. No significant effects of the magnetic treatment were recorded for the Gmáx . The magnetic treatment of seeds with homogeneous static fields does not have as favourable a response as the treatments with fields with magnetic gradients, that is to say, using toroidal magnets.

“…To stimulate seeds prior to sowing, some authors have subjected the seeds of various cash crops to different values of static magnetic fields for different durations [19]. Other authors have repeated the same processes as before but with sinusoidal electromagnetic fields of various frequencies [20]. The presowing stimulation of seeds with a variable electromagnetic field may involve specially designed electromagnets [21].…”

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 (V 1 and V 2 ) 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.

Relevance. High voltage electric power transmission lines (HVEPTL) cover a fairly large area of agricultural land all over the world. Investigations of electromagnetic field effect on growth and development of plants are held in various countries. The reaction of individual plant species and even varieties to the electromagnetic field manifests itself in different ways. The network of HVEPTL is growing steadily in our region as well. Nevertheless, information about the effect of the electromagnetic field on bean plants is rather scares. The aim of the present work was to evaluate HVEPTL effect on the growth and development of vegetable beans, depending on the intensity of the electromagnetic field.Material and Methods. The work was achieved on green beans Phaseolus vulgaris L. (Sakfit, Pagoda, MBZ 556, Arishka cvs) grown in conditions of different electromagnetic field values under HVEPTL. Biometrical parameters, plant productivity, yield, dry matter, photosynthetic pigments content, ascorbic acid, total antioxidant activity and total phenolics were determined.Results. In the ranges of electric field values from (5-10) to (400-440) B/m and magnetic field from 0 to 0.53 μT a beneficial effect of electromagnetic field on accumulation of leaves photosynthetic pigments (15-65% increase of chlorophyll а and 6-52% increase of chlorophyll b), polyphenol content (increase up to 17%), antioxidant activity (1-15% increase), and dry matter content (2,5-11% increase) and beans ascorbic acid levels (12-28% increase) were registered. Accordingy, increased plants growth, development and productivity were demonstrated. Peculiarities of beans plants grown under HVEPTL included decrease leaves carotene levels at electric field level of 60-100 B/m (70 m form HVEPTL), and lack of correlation between chlorophyll and carotene in leaves and total antioxidant activity and phenolics content at the stage of technical ripening.
