Abstract : Effect of essential oils extracted from Anethum graveolens, Origanum vulgare, Juniperus communis, Salvia officinalis and Satureja montana on seed germination and seedling growth of common ragweed (Ambrosia artemisiifolia) and giant ragweed (Ambrosia trifida) were studied. For germination studies seeds incubated one week in the Petri dishes containing 5 ml of diluted oil (500 µl oil + 500 µl 70% ethanol / 100 ml distilled water) in the dark at 25 oC. In order to test effect of diluted oils on seedling growth, seeds germinated on destined water and when germinated (at the moment of radicle emergence) were transferred into Petri dishes containing 5 ml of diluted oil. Our results confirmed that some tested essential oils possess inhibitory effect, while some stimulate germination of ragweed species. Also, inhibitory effect on seedling growth were confirmed, except for the oil of J. communis, which slightly stimulated growth of common ragweed seedlings.
