| Summary: | On the basis of biotesting of the different parts and organs of Echinacea purpurea plants (Echinacea purpurea (L.) Moench) cultivated in Poltava region it has been established that plants of the first vegetation year showed higher allelopathy activity compared with plants of the second year. The most perceptible hamper effect was typical to stem extracts of Echinacea purpurea of the first year existence. Allelopathy active components are accumulated more in an overground part than in a root system. It should be taken into account during agroecological evaluation of phytocoenosis. |
