Recently, growth regulators of natural origin have been used in fields with winter wheat crops. As scientific research and practice prove, these preparations help cropsto better absorb micro and macro elements, solar energy, and water in variousenvironmental conditions. Especially winter wheat during its life cycle, plants are affected by many stress factors, such as drought resistance, water deficiency, and saltstress. Our research aims to study the effect of the Paulownia tomentosa plant extract on thebiometric and quality indicators of winter wheat to improve cultivation technology. The object of research is the polyprenol of the extract of the plant P. tomentosa and thestimulant Uchkun - stimulating the synthesis of auxins. Crops were processed at thetime of the exit phase into the tube. The subject of research was the most commonwinter wheat variety Grom and the local winter wheat variety Bunyodkor. As a resultof the studies, it was found that the polyprenol of P. tomentosa and stimulant Uchkun, under conditions of drought resistance during the growing season in the Kashkadaryaregion, contributed to an increase in the content of chlorophylls, the amount of greenmass, the coagulation temperature of water-soluble proteins in the leaves of winterwheat. In the experimental variant with the use of polyprenol, the value of the sum of chlorophylls in the leaves increased by 5.6% compared to the control variant and amounted to about 56.2%. The use of the Uchkun stimulator in the winter wheat cropsof the Bunyodkor variety responded with an increase to the control within 14.0%, and the value of this indicator was 58.5%. The temperature of coagulation of water-soluble proteins in the leaves of winter wheat Grom and Bunyodkor variety ranged from 58°Cto 59°C during the phases of budding and heading.
