Effect of Pre-sowing Magnetic Field Treatment on Some Biochemical and Physiological Processes in Faba Bean (Vicia faba L. spp. Minor)

Abstract

The aim of this paper was to determine the changes in some biochemical and physiological processes, which occurred in seeds and seedlings of faba bean and to evaluate the germination dynamics and plant emergence after pre-sowing seeds treatment with a magnetic field. The study was carried out on Petri dishes in climatic chambers of the company HERAEUS (Germany). Each plate was lined with filter paper and 80 seeds of faba bean were sown. The paper was sprayed with the same amount of distilled water in each plate. Treatment of seeds significantly increased the activity of amylolytic enzymes in faba bean seeds and seedlings. The greatest differentiation in enzymatic activity between stimulated and nontreated seeds was noted after 96 h from the time of sowing. Seeds treated with the magnetic field showed greater dynamics of weight at the time of imbibition than nontreated seeds. Treating of seeds with a magnetic field considerably increased the amount of indole-3-acetic acid and gibberellic acid in germinating seeds, above-ground parts and in roots of faba bean seedlings. The pre-sowing treatment with a magnetic field had favorable effects on the growth and development of seedlings.

Effects of Electromagnetic Fields and their Shielding on the Growth of Dwarf Runner Beans

“…The authors also observed the increase in Fe, Cu, Mn, Zn, K and Na contents with a reduced level of Ca. Treating faba bean seeds with 30 mT magnetic field for 15 s increased amylolytic enzymes activity in seeds and seedlings and had a beneficial effect on seedling growth and development [27]. Yadav et al [28] observed a higher activity of α-amylase, ß-amylase, catalase and peroxidase in rice seeds subjected to 25 mT magnetic field for 15 to 90 min compared to untreated seeds.…”

Magnetic Field Treatments Improves Sunflower Yield by Inducing Physiological and Biochemical Modulations in Seeds

“…Magnetic field is a kind of energy treatment, which is absorbed by electron in different molecules and then used for accelerating the seed metabolism that trigger the biochemical and enzyme reaction to help in early seed germination [ 13 ]. The higher concentration of indole-3-acetic acid and gibberellin acid as well as higher imbibition rate was observed in germinating seeds of faba bean [ 33 ]. Improved emergence of magnetically treated seeds is the outcome of high concentration of secondary metabolites, enzymatic activity, and anti-oxidative capacity [ 39 , 41 ].…”

“…Magnetic field pretreatment increased seed germination rate, seedling growth and yield [ 32 ] of cumin. The beneficial effect of magnetic seed stimulation has been associated with various biochemical, cellular, and molecular events including enzymatic stimulation and bioenergetic excitements [ 33 ] and synthesis of proteins. Ion cyclotron resonance, radical pair mechanism [ 34 ] and formation of radicle pair by cytochromes have been reviewed as magnetoreceptors in plants [ 35 ].…”

Effects of Electromagnetic Fields and their Shielding on the Quality of Carrot (Daucus Carota L.) Seeds

“…Zardzewialy et al [28] found that sugar beet seeds exposed to magnetic field induction of 40 mT and 50 Hz frequency for 60 s germinated significantly faster than control seeds. According to Podlesna et al [29] seeds stimulated with magnetic field imbibe and germinate faster than untreated ones because of more advanced enzyme activity. Seedlings grown from stimulated seeds produce longer sprouts and roots and often have better vigour.…”
