SOWING QUALITIES OF SEEDS, MORPHOLOGICAL AND PHYSIOLOGICAL INDICES OF WINTER WHEAT PLANTS IN THE INITIAL PERIOD OF THEIR GROWTH AND DEVELOPMENT, DEPENDING ON THE INFLUENCE OF VARIOUS EXOGENOUS FACTORS ON SEED FORMATION
The results of studies conducted on winter wheat Orenburgskaya-105, cultivated on south chernozem soil of Orenburg Preduralye, are submitted in the article. The purpose of the research was to study the sowing qualities of seeds, the morphological and physiological characteristics of winter wheat plants in the initial period of their growth, depending on the influence of outside-the-roots application of growth regulators and fertilizers, based on humic acids, on the formation of seeds. The Immunotsitofit and Ribav-Extra growth regulators and the Rostok fertilizer, based on humic acids, have been used. The outside-the-roots fertilization was carried out in two terms - at the start of sprouting and at the start of ear formation. As result of studies conducted, it was revealed that in the process of the Orenburgskaya-105 winter wheat variety growing, the application of Ribav-Extra, Immunocytophyte growth regulators and the Rostock preparation, in the above stages of growth, did not have any negative effects on the seeds sowing properties and thus could be used to increase seed crops yields.
