Вплив Екологічно Безпечного Регулятора Росту На Перерозподіл Вуглеводів Та Азоту Між Органами Рослин Олійних Культур

Abstract

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.
