| Sumario: | The article is dedicated to the study of the dynamics of allelopathic activity of secretions (water-soluble, alcohol-soluble and
volatile) from vegetative and generative organs of the plants of Dracocephalum moldavicum L. species. Allelopathic effect of
water-soluble and alcohol-soluble extracts had exclusively phytotoxic activity on selected test objects regardless of growing
conditions and plant organs, except for the extracts from Moldavian dragonhead leaves under environmental conditions of
Uman city at the beginning of the growing season and in the budding phase. An interesting result was also noted concerning
the volatile secretions of Moldavian dragonhead, which were the most active toward the acceptor. Roots of garden cress among
the test objects were sensitive to the inhibitory effect of water-soluble secretions. Extracts of leaves and inflorescences showed
sufficiently high phytotoxicity. |
