“…Maize seeds exposed to magnetic field of 125 mT or 250 mT for varying periods of time germinated faster and the treated seedlings grew higher and heavier (Flórez et al 2007). Kubisz et al (2012) found that low-frequency magnetic field (10, 30, and 60 min) improved germination capacity of onion seeds, while most doses with longer treated time did not significantly improve the germination rate. A longer exposure of seeds to SMF might be detrimental.…”

“…Recently, several studies have reported the positive effects of static magnetic fields (SMF) on seed germination. For instance, magnetic field applied to plant seeds was found to increase the rate of germination and the subsequent seedling growth of onion (Kubisz et al 2012), wheat (Pittman & Ormrod 1970;Hussein et al 2012), sunflower (Vashisth & Nagarajan 2010;Matwijczuk et al 2012), tobacco (Aladjadjiyan & Ylieva 2003), maize (Flórez et al 2007), and date palm species (Dhawi & Al-Khayri 2011). Maize seeds treated with 150 mT SMF showed an increased germination, a higher fresh weight and the shoot length were longer than control (Aladjadjiyan 2002).…”

Based on preliminary experiments, the speed of germination (SG) was in general increased for Pinus taeda L. seeds treated with a static magnetic field (B = 150 mT) for 10, 30 and 60 min. Negative impact was obtained for seeds treated with SMF for 24 h and 48 h. Mean germination time (MGT), the SG, and time required to obtain 10%, 25%, 50%, 75%, and 90% of seeds to germinate (T 10 -T 90 ) were calculated. Results showed a reduction of the MGT and T 10 -T 90 for seeds treated with SMF for 10, 30, and 60 min; therefore, the germination speed was increased. Among various magnetic treatments, loblolly pine seeds treated with S3 (SMF60 min) yielded the peak performance.

“…Both static (i.e., stationary) and alternating magnetic fields have been used for seed stimulation. The induction of fields used for seed treatment varied from 3 mT (Soltani et al 2006a Treatment of seeds with magnetic field had a positive effect on the germination energy (Kubisz et al 2012;Krawiec et al 2013;Hołubowicz et al 2014). Stimulation of onion seeds with low frequency magnetic field (LFMF) 20 mT for 10, 20 and 30 minutes caused an increase of that parameter.…”

Due to the common trend towards limitation of excessive use of chemicals in agriculture, there is a growth of interest in methods of seed quality improvement that would be safe for the environment. These include methods based on the effect of various physical factors, such as laser light, magnetic field, seed treatment with magnetized water, electric field. The work provides detailed information on the impact of seed stimulation of these factors on germination, growth, development and yielding of horticultural plants. Summarizing the results of the study, it can be concluded that the application of physical factors in appropriate doses can be an effective way to enhance many plant parameters that increase their productivity. The beneficial effects of seed stimulation are mainly related to the first stages of plant life, i.e. – germination, emergence and growth of seedlings. In many cases, the enhancement of these features is also the result of the increase of plant yields. The increase of yield is even several dozen percent. The results of the study encourage the implementation of these physical methods of seed quality improvement into agricultural and horticultural practice.

“…There are some known publication works relevant to the treatment of both large-seeded crops (wheat, soya, rice, and French beans) and small-seeded crops (carrot, tomato, beet, onion) [1][2][3][4][5][6][7][8][9][10][11][12][13]. The effect of microwave electromagnetic radiation allows saving seeds from pathogenic microflora, which subsequently in future will positively affect the increase of power growth, plant vitality, and final yield [1][2][3].…”

“…The effect of microwave electromagnetic radiation allows saving seeds from pathogenic microflora, which subsequently in future will positively affect the increase of power growth, plant vitality, and final yield [1][2][3]. As a rule, seed treatment by other electromagnetic fields is directed to improving their sowing qualities (germination energy and germination capacity) that can be supposedly explained by the field effect on the processes of intracellular metabolism of seeds [4][5][6][7][8][9].…”

The article considers the presowing seed treatment by pulse electric field under the laboratory conditions to improve their sowing quality. The tests were carried out in each treatment mode in fourfold repetition with 100 seeds in each repetition to have reliable experimental data. The control was untreated seeds. The control and tested seeds had initial moisture content-11 %. The control and tested seeds were put for germination into sterile Petri dishes on a bed of filter paper being wetted by distilled water. The analysis of the obtained experimental data was conducted by the methods of mathematical statistics with applying computer calculation according to the task-level programming. The following parameters suitable for practical application of the rational mode of presowing treatment of onion seeds were established: the amplitude and the voltage pulse duration were correspondingly equal to 200V and 35 µs, pulse frequency-600 Hz, time treatment-8 s.At the same time, the seed germination energy was increased by 7.9 % on the average, and germination by 8.5 % compared with the control untreated seeds. The rational parameters of the presowing treatment mode of onion seeds have been obtained experimentally, allowing to increase the seed germination energy by 7.9 % (up to 77.9 %), on the average and germination by 8.5 % (up to 91 %) in comparison with the control untreated seeds. The given rational mode can be practically used to improve sowing quality of onion seeds prior their sowing.
