The geomagnetic field (GMF) is a natural component of our environment. Plants, which are known to sense different wavelengths of light, respond to gravity, react to touch and electrical signaling, cannot escape the effect of GMF. While phototropism, gravitropism, and tigmotropism have been thoroughly studied, the impact of GMF on plant growth and development is not well-understood. This review describes the effects of altering magnetic field (MF) conditions on plants by considering plant responses to MF values either lower or higher than those of the GMF. The possible role of GMF on plant evolution and the nature of the magnetoreceptor is also discussed.

“…Moreover, hydropriming (48 hrs) for tomato and sand matrix priming (80% water holding capacity, 3 days) for eggplant and chilli were established as best methods of priming treatment capable of improving seed vigour (Venkatasubramanian & Umarani, 2007). Furthermore, a low frequency magnetic field (16 Hz) can be used as a method of post harvest seed improvement for different plant species, especially for seeds of temperature-sensitive species germinating at low temperatures (Rochalska & Orzeszko-Rywka, 2005).…”

ABSTRACT. The objective of this study was to assess the comparative efficiency of different priming techniques on germination and early seedling growth of maize cultivars. Laboratory experiments were conducted to examine the efficacy of different seed invigoration treatments on seed germination and vigor traits of three maize hybrids, Pioneer 3025, Pioneer 70 and Baber at Agronomy research laboratory, University of Agriculture, Peshawar, Pakistan. The experiment was laid in completely randomized design (CRD) and was replicated thrice.The treatments included control treatment (T 1 ) unsoaked/dry seed, (T 2 ) hydropriming with distilled water for 24 hrs, (T 3 ) halo priming treatments with NaCl (3% solution) for 24 hrs, (T 4 ) osmopriming with PEG-6000 for 24 hrs and (T 5 ), hormonal priming with GA 3 for 24 hrs. The results showed that seed invigoration treatment with gibberellic acid (GA 3 ) PEG-6000 and hydropriming with distilled water for 24 hrs gave higher germination, decreased days to 50% germination, increased shoot length, root length, seedling fresh and dry weight, as compared to halo priming with NaCl and control treatment. It is concluded that seed invigoration with GA 3 , osmopriming with PEG-6000 and hydropriming with distilled water for 24 hrs serve as an appropriate treatment for accelerating the emergence and growth parameters of maize hybrid. Pioneer 3025 showed its superiority over other cultivars in all the studied parameters.

“…Today it is known that MF has positive effects on plant characteristics such as seed germination, shoot development, fresh weight and plant length, fruit yield per plant, and average fruit weight [Danilov et al, 1994;Namba et al, 1995;Aladjadjıyan, 2002;Esitken, 2003;Rochalska and Orzeszko-Rywka, 2005;De Souza et al, 2006]. MF was shown to induce germination in wheat, soybean, cotton [Phirke et al, 1996a], barley , rice , oak [Celestino et al, 2000], tomato [Moon and Chung, 2000], lettuce , corn [Florez et al, 2007], and chickpea [Vashisth and Nagarajan, 2008].…”

Magnetic field (MF) can have different effects on plant metabolism depending on its application style, intensity, and environmental conditions. This study reports the effects of different intensities of static MF (4 or 7 mT) on seed germination and seedling growth of bean or wheat seeds in different media having 0, 2, 6, and 10 atmosphere (atm) osmotic pressure prepared with sucrose or salt. The germination percentages of the treated seeds were compared with untreated seeds germinated in different osmotic pressure during 7 days of incubation. The application of both MFs promoted the germination ratios of bean and wheat seeds, regardless of increasing osmotic pressure of sucrose or salt. Growth data measured on the 7th day showed that the treated plants grew faster than control. After 7 days of incubation, the mean length of treated seedlings was statistically higher than control plants in all the media. The greatest germination and growth rates in both plants were from the test groups exposed to 7 mT MF. Strikingly, effects of static MF on germination and growth increased positively with increasing osmotic pressure or salt stress compared to their respective controls. On the other hand, MF application caused an increase in dry biomass accumulation of root and shoots of both seedlings; however, this effect was found statistically important in all the conditions for wheat but not for bean, in general.
