The focus of the research is allelopathic activity of Patrinia scabiosifolia and Patrinia rupestris. Secondary metabolites of higher plants, which regulate growth, are of interest as the basis for possible agents to be used in crop production. In order to study the phytogenic field, soil samples were selected. Gramineous and forb plant association soil was used as control. Cucumber seeds (Cucumis sativus) were used as test culture to identify the allelopathic activity of the phytopathogenic field. The results were analyzed by methods of mathematical statistics using Statistica 6.0. The bioassays of soil samples showed pronounced phyto-activity of the samples tested, which owes to secretions of parts of the donor plants. The results obtained may be used for commercialization of P. scabiosifolia and P. rupestris material as a source of biologically active substances possessing sedative and adaptogenic properties, as well as in crop production. Metabolites of P. rupestris manifest an inhibitory action, with maximum impact on the test crop caused by generative parts and leaves. Metabolites of parts of P. scabiosifolia did not have a meaningful impact on germination of test cultures and had a stimulating effect on the development of seedlings. https://biomedpharmajournal.org/vol10no2/allelopathic-activity-of-patrinia-scabiosifolia-and-patrinia-rupestris/ Allelopathic Activity P. scabiosifolia P.Phytopathogenic Field rupestris
