Popis: |
The main trend of modern crop production is the expansion of the use of plant protection solutions and technologies, that ensure not only effective management of the number of populations of harmful organisms, but also the production of environmentally safe agricultural products with minimal anthropogenic impact on agro-ecosystems. One of our priorities is to develop new environmentally sound polyfunctional biopreparations, that combine useful properties of microbial strains such as phytopathogen antagonists and chitosan compositions that increase disease resistance. The introscopic analysis of the seed material quality realized with the non–destructive express techniques application was used for evaluation the effectiveness of the compositions' complex influence on plants. The research studies the effectiveness of the influence of Bacillus subtilis strains and chitosan compositions, including their combined effect, on soft wheat productivity and its damage by disease agents. Data on the quality assessment of the grain using microfocus x-ray radiography and gas-discharge visualization (electrophotography) are also provided. The complex of more than 20 structural elements of wheat productivity was analysed during the research. Assessment of the plant damage intensity according to the standard criterion – the disease development, and additional phytopathological indicators was carried out. The evaluation of the grains’ introscopic characteristics was carried out by the microfocus x-ray radiography techniques combined with the digital x-ray image analysis. It is shown that the biopreparation complexes, containing B. subtilis strains and Chitosan, have a combined biological activity manifested in the optimization of wheat plants’ physiological state, increasing productivity, diseases resistance. |
