Features of development of corn root system of hybrid Dniprovskyi 181 CB under the influence ofthe microbial preparation Polimiksobakteryn (biological agent os which Paenibacillus polymyxa KB is anactive producer of physiologically active substances) were investigated in a vegetation experiment. It hasbeen established that the use of Polimiksobakteryn for pre-sowing bacterization of deeds and surfacetreatment of the vegetative plants in a phase of 3-5 or 7-9 leaflets induces increase in the size of the rootsystem and its adsorption surface. It was shown that the bacteria Paenibacillus polymyxa KB is aproducer of phytohormone substances of auxin nature, which explains the ability of the microbialpreparation Polimiksobakteryn to positively influence the processes of growth and development of the rootsystem.

The purpose of the research was to identify growth stimulators that promote the activa-tion of growth processes and root formation, to improve the technology of growing high-quality own-rooted grape seedlings from shortened three-eyed cuttings. The influence of physiologically active substances (PAS): Epin, Silk, Kornevin, Nikfan, Kavkaz on sur-vival, activation of growth processes, root formation of shortened cuttings of Bianca grapes was determined. As a result of pro-cessing cuttings with PAS, the survival rate of cuttings in the nursery increased by 10.6–19.1 % relative to the control. The yield of seedlings of the variety in the experimental variants exceeded the control indicators by 2.8–18.4 %. The effect of preparations on plant growth was noted, the increase in one-year growth in the variants varied from 5.8 to 18.0 cm relative to the control. When the ba-sal part of the cuttings was briefly immersed in a 0.01 % solution of Nikfan, the growth length was 78.1 cm, when soaked in a 0.1 % solution of Kornevin – 76.8 cm, in a 0.1 % solution of Silk –75.5 cm, in the control this indicator was 60.1 cm. The positive effect of growth stimulants on the development of the root system has been established. The indica-tor of the average number of roots per own-rooted seedling for the variants varied from 10.5 to 12.5 pcs., in the control variant – 10.7 pcs. According to the complex of indi-cators, a variant with the treatment of the ba-sal part of the cuttings for 24 hours with the preparation Kornevin-0.1% was identified.

Application of microbial preparations in the technologies of decorative plant cultivation promotes uptake of biological nitrogen and phosphorus, increases population of beneficial soil microflora, causing favorable effect on growth of green plantations. The studies have shown that introduction of nitrogen fixing and phosphate mobilizing bacteria into the rhizosphere of floral, deciduous and coniferous decorative shrubby arboreal species had risen the biogenic potential of rhizospheric soil, had stimulated the growth and development of ornamentals by increasing plants height and forming big healthy root system, as well as had facilitated early budding and blossoming in floral species.

The detection of viruses, disease biomarkers, physiologically active substances, drugs, and chemicals is of great significance in many areas of our lives. Immunodetection technology is based on the specificity and affinity of antigen–antibody reactions. Compared with other analytical methods such as liquid chromatography coupled with mass spectrometry, which requires a large and expensive instrument, immunodetection has the advantages of simplicity and good selectivity and is thus widely used in disease diagnosis and food/environmental monitoring. Quenchbody (Q-body), a new type of fluorescent immunosensor, is an antibody fragment labeled with fluorescent dyes. When the Q-body binds to its antigen, the fluorescence intensity increases. The detection of antigens by changes in fluorescence intensity is simple, easy to operate, and highly sensitive. This review comprehensively discusses the principle, construction, application, and current progress related to Q-bodies.
