title: ALLELOPATHIC ACTIVITY OF THE VEGETATIONAL MASS SECRETIONS OF MOLDAVIAN DRAGONHEAD SPECIES (DRACOCEPHALUM MOLDAVICUM L.)
abstract: 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.
