“…Scientists have found an induction of primary root curvature in radish seedlings in a static magnetic field, roots responded tropically to magnetic field with the tropism appearing to be negative; these roots responded significantly to the south pole of the magnet (Yano, et al 2001). The application of magnetic field doses of 4 mT and 7 mT promoted germination ratios of bean and wheat seeds (Cakmak, et al 2010). Magnetic treated pea plants grew higher and heavier than control; the greatest differences were observed for seeds treated with doses of 125 mT and 250 mT, for 24 hours or permanent.…”

“…It has shown that magnetic and electromagnetic treatments enhance the salinealkali tolerance (Xi et al, 1994), enhance seed germination and seedling growth under heat stress (Ružič and Jerman, 2002;Cakmak et al, 2010), and improve plant osmotic tolerance (Karimi et al, 2012). In contrast, Yao et al (2005) showed that MF treatments enhanced sensitivity of cucumber seedlings to UV irradiation.…”

This study evaluates seed germination and growth of sweet corn under NaCl stress (0, 50, and 100 mM), after exposing the seeds to weak (15 mT) or strong (150 mT) magnetic fields (MF) for different durations (0, 6, 12, and 24 hours). Salinity reduced seed germination and plant growth. MF treatments enhanced rate and percentage of germination and improved plant growth, regardless of salinity. Higher germination rate was obtained by the stronger MF, however, the seedling were more vigorous after priming with 15 mT MF. Proline accumulation was observed in parallel with the loss of plant water content under 100 mM NaCl stress. MF prevented proline accumulation by improving water absorption. Positive correlation between H 2 O 2 accumulation and membrane thermostability (MTI) was found after MF treatments, which revealed that MF primed the plant for salinity by H 2 O 2 signaling. However, over-accumulation of H 2 O 2 after prolonged MF exposure adversely affected MTI under severe salt stress. In conclusion, magnetic priming for 6 hours was suggested for enhancing germination and growth of sweet corn under salt stress. IZVLEČEK INDUKCIJA TOLERANCE NA SOL SLADKE KORUZE S PREDHODNIM OBRAVNAVANJEM SEMEN Z MAGNETNIM POLJEMV raziskavi sta bili ovrednoteni kalitev in rast sladke koruze v razmerah solnega stresa (NaCl; 0, 50, in 100 mM), po izpostavitvi semen šibkemu (15 mT) in močnemu (150 mT) magnetnemu polju (MF) v trajanju 0, 6, 12, in 24 ur. Slanost je zmanjšala kalitev semen in rast rastlin. Obravnavanje z magnetnim poljem je povečalo hitrost in odstotek kalitve ter izboljšalo rast rastlin, ne glede na slanost. Kalitev je bila značilno večja pri obravnavanju z močnejšim magnetnim poljem, kalice so bile bolj vitalne pri obravnavanju z 15 mT MF. Akumulacija prolina je bila opažena sočasno z izgubo vsebnosti vode v razmerah močnega NaCl stresa. Obravnavanje z magnetnim poljem je izboljšalo absorbcijo vode in preprečilo akumulacijo prolina. Pozitivna korelacija med akumulacijo H 2 O 2 in termostabilnostjo membran (MTI), ki je bila opažena po obravnavanju z MF je pokazala, da so bile tako obravnavane rastline odpornejše na slanost preko H 2 O 2 signalizacije. Kljub temu je prekomerna akumulacija H 2 O 2 , kot posledica podaljšane izpostavitve MF, negativno vplivala na MTI v razmerah solnega stresa. Zaključimo lahko, da predobravnavanje semen z magnetnim poljem za 6 ur pospeši nihovo kalitev in rast rastlin v razmerah solnega stresa. Ključne

“…Application of magnetic fields of extremely low frequencies positively affects seed germination, shoot development, plant length, fresh weight, fruit production and mean fruit weight (Cakmak et al, 2010). The positive effects of magnetic fields have also been shown in the biosynthesis of proteins, cell production, photochemical activity, respiration rate, enzyme activity and nucleic acid content (Stange et al, 2002).…”

Seed treatments are the biological, physical and chemical agents and techniques applied to seed to provide protection and improve the establishment of healthy crops. The benefits of seed treatments are increased germination, uniform seedling emergence, protect seeds or seedlings from early season diseases and insect pests improving crop emergence and its growth. Anthropogenic changes of the soil, water and atmosphere due to the use of different chemical additives for raising plants productivity led to searching alternative ways. Safe methods for increasing the yield includes the reasonable use of chemicals and substitution of some of them by appropriate physical treatments viz., magnetic field, gamma irradiation, electric field, laser irradiation, sound, healing energy, light and heat.Key words: Energy treatment, Germination, Seedling vigour, Seedling growth, Seed yield.Recently the use of physical methods for plant growth stimulation is getting more popular due to the less harmful influence on the environment. Physical factors can be used to get positive biological changes in crop plants without affecting the ecology. Growth, development and yield of dill seed is accelerated using physical treatment. All living processes are highly dependent on energy exchange between the cell and the environment. This is the core concept in "quantum agriculture" that has been intensively discussed in the last decades (www.btinternet.com). Energy treatment is an innovative area of research to improve the yield of crops. It initiates physiological and biochemical changes, which reflect the plant growth and development processes and ultimately improve the yield and quality of produce. Treatment led to change of seed vitality indices (germinating energy, germination, and uniformity of germination): In this paper, different types of energy treatments viz., magnetic field, gamma irradiation, electric field, laser irradiation, sound energy, healing energy, light and heat energy on germination, seed yield and quality of agriculture and horticulture crops. MECHANISM INVOLVED IN ENERGY TREATMENTPhysical factors import different kind of energy into the cells. It is a kind of energy treatment that stimulates the enzymes and other biochemical reactions that helps in early germination. Imported energy is absorbed by the electrons in different molecules. The absorbed energy may be transformed in another kind of energy (most probably chemical one) and then used for accelerating the seed metabolism. It helps to elucidate the mechanisms of energy exchange in molecules and thus stimulation of plant development. In the case of chemical amelioration the necessary substances are directly inserted into the cell. Whereas in the physical treatment, energy introduced in the cell creates conditions for molecular transformations. Magnetic field energy:Application of magnetic fields of extremely low frequencies positively affects seed germination, shoot development, plant length, fresh weight, fruit production and mean fruit weight (Cakmak et al.,...
