“…Allelopathy is a natural phenomenon that has a significant impact on the functioning of biocenoses. The phenomenon of allelopathy includes various types of chemical interactions between organisms and is carried out by the formation and release of metabolites with allelopathic activity into the environment (Polyak et al, 2019;Aci et al, 2022;Hussain et al, 2021). The term "allelopathy" is most often used to characterize the relationships between plants, but it is also widely used to describe the relationships between microorganisms and between plants and microorganisms (Kucheryavay, 2020; Zorikova et al, 2017).…”

“…Ukrainian Black Sea Region Agrarian Science, 26 (4), [19][20][21][22][23][24][25][26][27][28][29] According to M. Shinwari et al (2013), 70 species of Japanese plants were examined for allelopathy using the aqueous extraction method. The scientists concluded that before large-scale cultivation of any medicinal plant in an established agricultural field, the plant should be evaluated allelopathically, as chemical exposure from previous plants, residues, related plants and even autotoxicity can adversely affect the cropping system.…”

The need for phytoremediation prompts the introduction of plants into the culture, which will not only have several directions of use of the obtained raw materials, but also contribute to the improvement of the soil and be a good precursor for the further successful cultivation of the following agricultural crops. It is known that essential oil crops activate the development of beneficial microbiota and prevent soil fatigue. The article presents the results of research on the allelopathic activity of plant parts of medicinal hyssop (Hyssopus officinalis L.) of the Marquis variety, taking into account age characteristics under conditions of climate change in Southern Ukraine. The aim of the work was to reveal the influence of allelopathic activity of aqueous extracts of leaves, stems and flowers of hyssop, soil in the rhizosphere zone and plant age on the growth of watercress roots. In the research process, empirical methods were used, in particular, an experiment. As a result of research carried out with the medicinal hyssop culture of the first, second and third years of vegetation on the basis of the experimental field of the Mykolaiv National Agrarian University during 2019-2021, the optimal concentration of water extracts of the culture with a stimulating effect was found. The dependence of the allelopathic activity of water-soluble biologically active substances of aerial organs of medicinal hyssop plants is shown, and the concentration of the solution, which causes an inhibitory effect, is revealed. Thus, the highest allelopathic activity was noted on the variant using hyssop flowers of medicinal plants of the second year of vegetation in a concentration of 1:10. Aqueous solutions of the soil layer of the root system where medicinal hyssop plants grew in the third year of vegetation have an inhibitory effect on the linear growth of watercress roots. It was the largest in the leaf + stem variant at a concentration of the aqueous solution of 1:10. This suggests that it is necessary to use the culture of medicinal hyssop in crop rotation carefully taking into account its ontogenesis features. The obtained results will have practical application in enterprises of various forms of ownership that will have the desire to grow medicinal hyssop and use it in the structure of crop rotation

“…Em relação à este último parâmetro, tem-se que as plantas influenciam diretamente o ambiente rizosférico, podendo favorecer ou não a sobrevivência de determinados grupos microbianos (Mandon et al, 2021). Dentre os diversos compostos liberados pelas plantas, pode-se destacar os compostos alelopáticos ou aleloquímicos (Lorenzo et al, 2013;Polyak et al, 2019).…”

Objetivou-se com este estudo verificar a influência de compostos alelopáticos liberados por Brachiaria brizantha cv. Marandu na tolerância de bactérias promotoras do crescimento vegetal (BPCV). Foram obtidos extratos da parte aérea e raiz de B. brizantha nas concentrações de 12,5; 25,0; 50,0 e 75,0% e avaliado o efeito no crescimento de 10 estirpes de BPCV utilizando as metodologias de perfuração em ágar e diluição seriada. O experimento foi instalado em delineamento inteiramente casualizado (DIC) em esquema fatorial, 10 x 5 x 2 com 4 repetições, sendo 10 estirpes bacterianas, 5 constituindo as quatro diferentes concentrações e um tratamento controle (sem extrato) e 2 extratos de compostos alelopáticos, parte aérea e radicular, de B. brizantha. Foi verificado inibição pelo extrato radicular na concentração de 75% para as estirpes UNIFENAS 100-01; 100-13; 100-39; 100-02 e 100-94 pelo método da perfuração do ágar. As demais estirpes cresceram normalmente no meio de cultura em todas as concentrações. De acordo com os dados obtidos foi possível observar que os extratos alelopático de B. brizantha podem interferir no crescimento de estirpes de BPCV, podendo comprometer a eficiência destas quando utilizadas como inoculantes.
