| description | Abstract At the present time one of the tasks of modern agricultural industry consists in obtaining the ecologically safe and clean products. Contamination of soils with heavy metals due to an anthropogenic impact drives up their content in the composition of plant products. This shapes not only a reduction in crop yields, but also a deterioration in products quality. Within the terms of vegetation research in soil culture, there has been studied the protective and stimulating effect of sodium selenite upon the adaptive capacity of spring wheat plants of the variety Zlata under conditions of oxidative stress due to the soil contamination with cadmium. There has been studied the effect of different methods of sodium selenite application on the yield of spring wheat and the plants photosynthetic activity, depending on the level of soil contamination with cadmium. The object of research was a spring wheat variety Zlata. Plants have been cultivated in a greenhouse trial under soil culture conditions in Mitscherlich-vessels with a capacity of 6 kg of soil. Sod-podzolic soil has been used for research. Sodium selenite was introduced in three ways: pre-sowing seed treatment, foliar treatment of vegetative plants at the beginning of stage VI of organogenesis - the end of the tillering phase - the beginning of the stem-extension phase and the application of a salt solution into the soil when packing the vessels. The control samples represented variants without sodium selenite. To assess the plants photosynthetic productivity, there has been determined the chlorophyll content in plant leaves. The research results made it possible to determine the protective effect of sodium selenite on the adaptive capacity of plants under conditions of oxidative stress due to the soil contamination with cadmium. The increase in the adaptive capacity of plants manifested itself through the decrease in yield diminishing due to the improvement of conditions for fertile florets and ear initiations on the vegetative apex, as well as the development of flowers into grains, which contributed to increase in the grain content of the spike. The stimulating effect of selenium on the intensity of photosynthetic processes has been revealed, which showed not only the increase of chlorophylls content, but also the ratio changes of chlorophylls a and b. |
