“…In order to reduce the impact of stress factors on a plant organism, growth-regulators containing phyto-hormones and other synthetics growth-stimulators are applied. Their effect is directed towards prolongation of active photosynthesis, cessation of leaf apparatus activity and intensification of growth functions (Small et al, 2018;Mu et al, 2018;Panfilova et al, 2019Panfilova et al, , 2021.…”

The purpose of the study was to establish dependence of sunflower productivity on hybrid plasticity under the climatic conditions of the Steppe zone and effectiveness of growth-regulators on the basis of the analysis of differentiation of a vegetation index. The research on the development and productivity of different sunflower hybrids under the natural-climatic conditions of the Steppe zone of Ukraine was conducted in the years of 2019 (medium-wet), 2020 (dry) and 2021 (wet). Spatio-temporal differentiation of the vegetation of sunflower hybrids was established on the basis of calculation of a normalized difference vegetation index (NDVI) using the data of the decoded space images of Sentinel 2. Cartographic and grapho-analytical materials reflecting the reaction of plants to natural-climatic conditions and multifunctional growth-regulators were obtained. The dependence of the reaction of sunflower hybrids to multifunctional growth-regulators on their plasticity in response to the naturalclimatic conditions of the Steppe zone was established. There was a weak reaction to application of growthregulators of the sunflower hybrids Oplot and P64HE133 which are characterized by a high level of plasticity in response to the natural-climatic conditions of the Steppe zone. It was proven that the application of the biological preparation Helafit Combi exceeded the level of agrocenoses productivity in comparison with the chemical preparation Architect ТМ by 1.1-5.4%. It was established that foliar treatment with growth-regulators led to a decline in water uptake by the sunflower hybrids by 1.2-10.0% in the dry year, by 3.8-8.6% in the medium-wet year and by 3.7%-21.9% in the wet year. There was a significant reduction in the level of water uptake by the hybrid Hector -by 7.7-10.0% and the hybrid 8KH477KL -by 1.2-21.9%.The research results are the basis for forecasting the development of sunflower hybrid crops with further measurement of the crop productivity that allows establishing a probable level of efficiency of sunflower hybrid production by agricultural producers under the climatic conditions of the Steppe zone.

“…The yield indicator implements the effect of a set of factors on the plant organism during its growing season, and the yield is the result of a compromise between productivity and resistance to biotic and abiotic factors of the environment (Herrera et al, 2021). For maximum harvest indicators, the characteristics of productivity and stability must be selected and adjusted in such a way that in each individual case they best correspond to the conditions of the external environment (Domaratskiy et al, 2020;Panfilova et al, 2021).…”

Climate changes in recent decades have increased the degree of risks in crop production. The consequence of such processes is an increase in the temperature regime against the background of a significant moisture deficit in critical periods of plant growth and development. Accordingly, research aimed at establishing the adaptability of plants to such climatic changes is relevant and timely. The purpose of the research is to establish the principles of implementing the adaptive potential of new varieties of winter wheat of different types of development in the Steppe zone under the conditions of climate change. Records and their assessment were carried out according to the generally accepted methods of Ukrainian variety testing with mandatory statistical and dispersion analysis of the results of field experiments. The establishment of indicators of the stability of quantitative traits and plasticity was carried out using the Eberhard-Russell algorithm, which is based on a regression analysis of the dependence of the grain yield of winter wheat of different varieties on the environmental index. The results of the research established that universal type varieties with a stem length of 85-90 cm are the most suitable for irrigated and non-irrigated conditions. Regression analysis of the data on the plasticity and stability of the elements of the crop structure in different varieties of winter wheat proved that their variability directly depends on the genotype and ecological gradients. According to the results of the assessment of the adaptive potential, it was established that the parameters of plasticity (bi = 0.804-0.989) and yield (7.33-7.63 t/ha exceed the standard by 10.4-14.9%) showed winter wheat varieties of the universal type - Askaniyska, Askaniyska Bereginya, Perlyna, Znahidka Odeska, while Khersonska 99, Kirena, Yaroslavna, Kuyalnyk, etc. were characterized by an intensive type of development. Varieties of the universal type were more plastic and stable in the formation of ear productivity, compared to short and tall biotypes. The scientific significance of the research lies in the substantiation of scientific principles, practical recommendations for improving varietal agricultural technology of winter wheat, which had different genetic and ecological origins, in irrigated and non-irrigated conditions of the Steppe zone
