Abstract
In recent years, there has been a persistent search for new methods and technologies for cultivating specific crops to increase their productivity and improve product quality. The aim of the study was to obtain essential oil from poplar buds by the barothermal method, to standardize the obtained essential oil, to study the effect of an aqueous emulsion of poplar oil on the growth and development of tomato seeds. For obtaining the maximum yield of balsam poplar essential oil, the optimum pressure, input of raw material, and processing time were investigated. The essential poplar oil was standardized according to organoleptic and physico-chemical parameters. The study found that the use of an aqueous emulsion of poplar bud oil had a significant impact on the morphogenesis, physiological and biochemical parameters of tomato seeds.
