Influence of magnetic fields on the activity of enzymes: alpha- and beta-amylase and glutathione S-transferase [GST] in wheat plants

Abstract: The paper presents the impact of magnetic fields on enzyme activities in plants. Three species of wheat with different ploidy levels were used in the experiments: Triticum monococum (diploid), T. dicocum (tetraploid), and T. aestivum (hexaploid). Air-dry seed samples, made up of 100 seeds each, were treated with an alternating magnetic field of low frequency (16 Hz) for 2 h. The control samples were not tested with the magnetic field. After the 13th day of magnetic field treatment, measurements were conducted on the following enzymes: - and -amylase and glutathione S-transferase. The magnetic field caused a reduction in the activity of alpha- and beta amylases. This can be really important in breeding and seed production and in certain sections of the agricultural and food industry. Plants grown from treated seeds will be more resistant to sprouting in the future. The magnetic field caused a higher activity in the glutathione S-transferase enzyme. It caused that the plants have a higher resistan- ce to pathogen attack, oxidative stress, and heavy-metal toxicity.

Impact of low frequency magnetic fields on yield and quality of sugar beet

Abstract: Pre-sowing treatment of seeds using a low frequency magnetic field (16 Hz, 5mT) and its impact on the yield and quality of plants were investigated. Magnetic treatments increased the emergence of seeds, especially for low vigour seeds. The chlorophyll content also increased significantly. As a result, the yield of plant roots was increased. The magnetic field also influenced the content of sugar in the root of the beet.

Influence of alternating low frequency magnetic field on improvement of seed quality

Abstract: A b s t r a c t. The paper shows the influence of magnetic field on improvement of seed quality. Spring wheat kernels were treated with a 16 Hz alternating magnetic field. Magnetic induction of the field was 5 mT. The optimum time of treatment of wheat seeds with alternating magnetic field equals 2 h. The best germination of seeds starts around 20 days after being treated with magnetic field. Presowing stimulation with alternating low-frequency magnetic fields has a positive influence on wheat grains germination. K e y w o r d s: magnetic field, spring wheat, seed germination

Effect of magnetic field on germination and yield of wheat.

Abstract: A b s t r a c t. The effect of magnetic field on germination and yields of spring wheat is presented. In the performed experiment two magnetic doses: D11=D13= 12.9 and D21=D23=17.9 kJ m -3 s were applied. The germination kinetic and yield of wheat depended on both magnetic field exposure doses. In both cases the better germination of seeds as compared to control seeds was observed. The yield of wheat for the exposure doses D11=D13 was 12.5% higher and for doses D21=D23 was 14.5% higher than obtained for the control.

Alleviation of adverse effects of drought stress on growth and some potential physiological attributes in maize (Zea mays L.) by seed electromagnetic treatment.

Abstract: Effects of varying preseed magnetic treatments on growth, chlorophyll pigments, photosynthesis, water relation attributes, fluorescence and levels of osmoprotectants in maize plants were tested under normal and drought stress conditions. Seeds of two maize cultivars were treated with different (T0 [0 mT], T1 [100 mT for 5 min], T2 [100 mT for 10 min], T3 [150 mT for 5 min] and T4 [150 mT for 10 min]) electromagnetic treatments. Drought stress considerably suppressed growth, chlorophyll a and b pigments, leaf water potential, photosynthetic rate (A), stomatal conductance (g(s)) and substomatal CO(2) concentration (C(i)), while it increased leaf glycinebetaine and proline accumulation in both maize cultivars. However, pretreated seeds with different magnetic treatments significantly alleviated the drought-induced adverse effects on growth by improving chlorophyll a, A, E, g(s), C(i) and photochemical quenching and nonphotochemical quenching, while it had no significant effect on other attributes. However, different magnetic treatments negatively affected the g(s) and C(i) particularly in cv. Agaiti-2002 under drought stress conditions. Of all magnetic treatments, 100 and 150 mT for 10 min were most effective in alleviating the drought-induced adverse effects. Overall, preseed electromagnetic treatments could be used to minimize the drought-induced adverse effects on different crop plants.

Magnetic field as a method of improving the quality of sowing material: a review

Abstract: A b s t r a c t. The effect of magnetic field on the growth and yield of crop plants is presented based on 80 references on the studies of many authors. The introduction gives an outline of the history of the effect of magnetic field on biological organisms including plants since the second half of the 19th century. Then the role of static and alternating magnetic fields is discussed in relation to seed germination, root and stem growth, yield, protein and chlorophyll content, rhizosphere community.
