THE INFLUENCE OF THE IONIZING RADIATION ON THE WHEAT PLANTS AFFECTION BY THE STEAM RUST

Investigated have been 25 sorts of wheat and uredospores of the pathogene of the stem rust races 21, 11, 1K and the population have been studied. The work is aimed at studying the influence of the ionizing radiation on the wheat affection with the stem rust and at determining the possibility of application of the methods of prognosis and protection of plants, to be developed earlier, from the diseases under the conditions of the radiactive contamination of the agricultural lands. For the first time, the peculiarities of the wheat affection with the stem rust has been revealed, depending on the sort composition, the phase of the plants development and the stage of the pathological process of the fungus, the dose of radiation, the postradiation period and the factors of the outside medium. The possibility has been established and the proposals to the production have been given about the application of the existing systems of the chemical protection of the cereals cultures from the complex of the fungus diseases under the conditions of the ionizing radiation effects.
