Impact of plasma pre-treatment on winter wheat genotypes

One of the approaches to increase the crop yield under abiotic stresses is to improve the seed germination. Chemical methods are ofen used for this purpose but due their negative impact on human health and environment, their usage should be minimized as much as possible. Plasma treatment is a new physical technology in agricultural practice, which can promote the seed germination and growth of seedlings. Plasma is a fourth aggregate state with zero net electric charge of particles. It changes the chemical properties of seed coat by creating a special wetting ability. In this study, effect of liquid-plasma with several radiofrequency on wheat genotypes under drought exposure will be tested. Before drought treatments seeds of two wheat genotypes will be soaked in liquid-plasma medium for several minutes. Te effect will be tracked by measuring the germination rate, germination percentage, morphometric parameters such shoot and root length during several days under control and restricted water regime. Te drought will be applied by using polyethylene glycol (PEG), a moisture defcit stress inducing media. Tis research will provide a potential of non-invasive plasma method in improving the drought tolerance of winter wheat genotypes in early developmental stage. Moreover, the results of this study may be benefcial for the breeders in selection of genotypes with best traits.
