Abstract
In this study, various magnetic field intensities between 2.9 to 4.8 mT by 1ms-1speed applied to mature embryos of Flamura-85 wheat variety and effects of magnetic field on different physiological (regeneration rate, average plant fresh weights, and average plant lengths) and biochemical [total protein, and chlorophyll amounts, superoxide dismutase (SOD), catalase (CAT), peroxidase (POX) and ascorbate peroxidase (APX) enzyme activities] parameters were investigated. Compared to the control group, an increase was detected on physiological parameters of 2.2 and 19.8 s magnetic field applied Flamura-85 wheat variety. Total protein and chlorophyll amounts, SOD, CAT, POX and APX enzyme activities of 2.2 and 19.8 s magnetic field applied experimental groups presented increase compared to the control, depending on applied magnetic field intensity. Key words: Antioxidant enzymes, chlorophyll amount, growth parameters, magnetic field, plant tissue culture, protein amount, wheat.
Highlights
Magnetic field is an inevitable environmental factor for all living organisms (Esitken and Turan, 2004)
According to many researcher’s results on studies with different plants, it was reported that magnetic field (MF) affects plant growth positively and regeneration rate, plant fresh and dry weight, leaf number, length, shoot number, rooting rate increased compared to the control (Lucchesini et al, 1992; Corneanu et al, 1994; Yaycili and Alikamanoglu, 2005)
In the 3rd day after we applied magnetic field to the cultures regeneration, rates of all MF intensities were increased compared to the control
Summary
Magnetic field is an inevitable environmental factor for all living organisms (Esitken and Turan, 2004). There are several hypotheses trying to explain cellular responses of magnetic and electromagnetic field on biological systems. The first one is the orientation of particles which present ferromagnetic properties in living systems, and the other one is the energy level alterations and changes on electron spin conditions of ionic formed atom and molecules which present paramagnetic properties (Van et al, 1998). Various researchers assume that magnetic fields between 10-3 to 10-2 Tesla can effect chemical reactions by changing electron spin locations and in this manner they have potential to cause biological effects
