Abstract
Plant response to magnetic field stimulation (MFS) is varied and dependent on many factors such as the intensity, time of exposition, or application form. It is known that high intensity MFS inhibits the growth and development of plants. However, weak MF stimulates many processes in plant cells. This study reports the effects of 130-mT magnetic field stimulation (MFS) on the growth and selected biochemical parameters in the common bean (Phaseolus vulgaris L.) in laboratory conditions. Our results indicated that the stimulation of plants by a weak permanent magnetic field (130 mT) increased mitotic activity in meristematic cells of the common bean (P. vulgaris L.). There was no influence of the 130-mT MFS on the development of aboveground plant parts; however, there was a marked increase in GPOX activity in the leaves after 130-mT magnetic field stimulation.
Highlights
Both magnetic and electromagnetic field influence the functioning of biological organisms
The results of this study showed that the 130-mT magnetic field (MF) stimulation had a beneficial effect on cell mitotic activity in common bean (P. vulgaris L.) root meristems, and the mitotic index (MI) increased by 59%
We indicated that there was no significant effect of the 130-mT magnetic field stimulation (MFS) on the assimilation pigment content in bean (Phaseolus vulgaris L.)
Summary
Both magnetic and electromagnetic field influence the functioning of biological organisms. The optimal magnetic field stimulates plant growth and development or seed germination (Pietruszewski et al, 2001). It was observed that weak magnetic field stimulation had a beneficial effect on seed germination in radish (Novitskaya et al, 2001), root formation in wheat (Aksyonov et al, 2001), or formation of somatic embryos in cultures of alfalfa (Medicago sativa L.) (Dijak et al, 1986). The results obtained by researchers on the magnetic field stimulation are promising and important. Some species of legumes are used as animal fodder (Câmara et al, 2013) These properties have contributed to the selection of these plants for this study. The objective of our study was to investigate the influence of weak permanent magnetic field stimulation (130 mT) on the growth and selected biochemical parameters of the common bean (Phaseolus vulgaris L.)
