The aim of the research. Given that the existing data on the effect of growth inhibitors on the redistribution of assimilates in oil crops are not numerous and the controversial data on the effect of the anti-gibberellin drug chlormequat chloride on the content of carbohydrates and nitrogen the purpose of the experiment was to find out the influence of CCC on the redistribution of assimilates in oil crops.Methodology. Oil poppy and rapeseed plants of the Halytsky variety were treated during the budding period with a 0.5% solution of chlormequat chloride with a Mastertool hydraulic sprayer, while the plants of the control sample were treated with water. Experimental plots were laid in farms of the Podilskyi region in 2020-2021. The number of experimental plots of each of the experimental options is 5, the area is 5 m2. The content of total nitrogen was determined by the Kjeldahl method, sugars and starch content was measured using the iodometric method. The novelty of the research. The effect of a growth regulator on the redistribution of carbohydrates between plant organs during the growing season was for the first time investigated on the oil poppy culture. The accumulation of excessive carbohydrates in the leaves and roots of the experimental samples has a positive meaning due to the creation of a powerful reserve fund of assimilates. It is used for the formation and growth of the fruits of the oil poppy, the number of which increased. An increase in the content of carbohydrates in the vegetative organs of oil poppy plants under the action of chlormequat chloride was found to go along with a decrease in the content of total nitrogen in the roots and leaves both in the control sample and in the plants of the experimental variant.Conclusions. The usage of growth regulators in the budding phase causes an increase in the productivity of oil poppy and rapeseed culture. Under the action of these preparations, a correction of donor-acceptor relations in the plant is observed. It is implemented through the redistribution of assimilates from vegetative organs to the needs of carpogenesis. The formation of a more powerful acceptor sphere is associated with laying a larger number of fruits - the main acceptors of assimilates in the second half of the growing season. An increase in the load of the plant with fruits in the plants of the experimental variants also affected a more intensive flow of carbohydrates and nitrogen-containing compounds to them, which ultimately led to an increase in the seed yield.

“…Because of the effectiveness of the application, growth regulators of the inhibitory type -retardants -have become widespread, these are anti-gibberellin preparations that affect the donoracceptor relationship in the plant organism and slow down vegetative growth, redistributing the flow of photoassimilates to economically significant organs (Polyvanyi et al, 2020;Shevchuk et al, 2021). Moreover, physiologically active complexes as part of growth stimulants contribute to a more intensive course of metabolic processes, mitosis, activate enzyme systems, photosynthesis and air nutrition, improve plant resistance to diseases or fluctuations in environmental conditions (Bakry et al, 2013;Sang-Kuk et al, 2014).…”

“…It is important to note that these drugs have good ecological characteristics: they are low-toxic; have no carcinogenic and blastomogenic properties; the growth regulators donʹt accumulate and decompose in the organism, after two days they are excreted from it (Polyvanyi et al, 2020). The half-life period of chlormequat chloride in the soil is about 3 to 43 days, depending on the temperature and humidity.…”

Contemporary agrobiology is aimed at solving the problem of sufficiently stable agricultural crop yield, given the principles of eco-friendly nature use and mandatory monitoring of anthropogenic load on agrocenoses. Hormonal regulation of physiological functions, including the use of preparations based on phytohormones and modifiers of their activity, is one of the topical directions for tackling the problem of plant productivity. The article presents the research results of the effect of the inhibitor of antigibberellin action -chlormequat chloride -and the stimulator based on treptoleum phytohormones on the processes of morphogenesis, the formation of the photosynthetic apparatus, and the yield of flax plants. The plant height is established to decrease under the action of chlormequat chloride, and increase under the influence of treptolem. Both preparations caused an increase in the flax stem diameter. When applying growth regulators, the number of leaves and their total surface area, duration of functioning increased, which generally contributed to the improvement of the crop structure and flax plants productivity. Determination of the content of residual amounts of drugs was carried out on samples of leaves and stems of flax, while the complete absence or traces of chlormequat chloride was noted.

Tobacco plants of Ternopil 14 variety were treated with gibberellin inhibitors 2-CEPA, EW-250 and CCC-750. Under the influence of antigibberellins, the leaf blades of tobacco thickened due to the growth of chlorenchyma. The greatest increase in leaf thickness was found after the use of 2-CEPA and EW-25. These same drugs increased the volume of the cells of the columnar parenchyma. The size of the cells of the spongy parenchyma under the action of gibberellin inhibitors was reduced significantly.CCC-750 was found to increase the number of epidermal cells per unit abaxial leaf surface, while 2-CEPA and EW-250 decreased. All growth inhibitors reduced the number of stomata and increased the area of the stomata. All drugs thickened the layer of the primary periderm, and retardants thickened the layer of the collenchyma. EW-250 increased the size of sclerenchymal fiber cells, while other drugs reduced them. All antigibberellins thickened the membranes of sclerenchyma cells. Ethylene producer increased the thickness of the layer of the secondary periderm, and other drugs reduced this figure. EW-250 increased, 2-CEPA decreased, and CCC-750 did not change the thickness of the xylem layer. The diameter of the largest vessels decreased with 2-CEPA and CCC-750 and did not change after treatment with EW-250.
