Interactive effect of static magnetic field and abiotic stressors on growth and biochemical parameters of germinating wheat cultivars

In this study, the effects of the individual and combined application of the static magnetic field andabiotic stressors (60 gL-1 PEG6000 (as a drought stress inducer) or 100 mM NaCI (as a salinity stressinducer)) on the cultivars of germinating wheat were investigated by assessing growth, biochemicaland antioxidant defence parameters. The seeds of Nina and Flamura-85 species of bread wheat wereexposed to 2.9-4.7 mT static magnetic flow density for a period of 0, 2.2 and 19.8 seconds on a bandturning with the speed of 1 ms-1. Moreover, this magnetic field application was performed together withabiotic stressors and separately. The growth parameters of both wheat cultivars increased under the staticmagnetic field applications, while they decreased when subject to the abiotic stress application than thecontrol. The application of the static magnetic field together with abiotic stressors statistically increasedthe amount of • OH and H2O2 in root samples, and the total Chl, Chl a and Chl b amounts in leaf samples.The application of the static magnetic field together with abiotic stressors or separately significantlyincreased antioxidant enzyme activities (SOD, POD, CAT, APX and GR), and GSH and GSSG contentin all experimental groups when compared to the control. Consequently, that the application of themagnetic field triggers the antioxidant defence parameters reduced the negative effects of drought andsalinity stresses on the growth parameters in both species.
