Fruit growing
and viticulture of South Russia

Annotation

It is suggested that the effect of drugs as chemical substances with physiological activity at the molecular and cellular levels may be identical or similar for animal and plant organisms due to common targets of drugs, in particular, such as ion channels and enzymes. Research on the search for substances whose use at a certain critical stage of organogenesis of generative organs of a particular seed grape variety can induce embryo abortion and seedless berries without negatively affecting the conducting system of the grape comb, the degree of lignification of the comb, and the shedding of seedless berries is of relevance. An important condition and requirement for these drugs should be the environmental and biomedical safety of their use. The purpose of research is to screen physiologically active substances of pharm phytohormonal activity and are promising for use in viticulture. The research was carried out on the plantations of grapes Closed Joint-Stock Company them Sh. Aliyev (2004-2005) of the Republic of Daghestan and experimental basis of DSTSVH � branch NCFSCHVW (2017-2019). The object of research � the generative grape organs of Agadai and Moldova varieties, which occupies a large area in the Republic of Daghestan. The influence of pharmacological preparations isolated at the stage of virtual screening on the development of ovary elements when used at the stage of pollination (blossoming) and post-fertilization (7 days after mass blossoming) was studied. The standard was classical growth regulators with different mechanisms of action � analogs of phytohormones. Screening and initial assessment of the pharmacological drugs effect of various classes the generative grape organs were carried out. A stimulating effect the weight of berries was found levamisole (+11%), dibazole (+18 %), mercazolil (+32%), methyluracil (+41 %) and ranitidine (+60%) during post- fertilization treatment. Treatment by pyrantel and nifedipine of inflorescences at the stage of pollination reduces the number of seeds and their weight in the berries, which leads to increasing a seed index of Agadai variety by 2.5 times Nifedipin increases in seed index Moldova variety by 1.5 times. Pharmacological preparations can be promising for use in the technology for obtaining the seedless berries, speeding up the beginning of crop maturation, increasing in the yield and quality of seed grapes without adversely affecting the commercial value, environmental and biomedical safety of products.
