De zaden van deze parasiet kiemen enkel als antwoord op één of meerdere specifieke chemische signalen die afgescheiden worden door de wortels van de gastheerplant. Zo kiemen Orobanche ramosa en O. cumana zaden enkel in aanwezigheid van hun respectievelijke gastheren tabak en zonnebloem.

Broomrapes (Orobanche spp.) are obligate root parasites of many crops. Parasitism by the root parasites often results in severe yield losses. The seeds of those parasites germinate only in response to specific chemical signal(s) released from the host plant roots. Orobanche ramosa and O. cumana seeds germinate in the presence of their respective host tobacco and sunflower. A determination of the germination stimulants released from sunflower and tobacco roots is of great importance from a theoretical and practical point of view. The aim of this study is to clarify the correlation between the dynamic in quantity of plant hormones during the infection process and their role for triggering the defense reaction of the host plant. Determination of the nature of the plant host specific substances responsible for provoking the parasite seed germination will be our main goal. These experiments will give an opportunity to study the interactions between hosts and parasites and to go in more details by biochemical investigations of the chemical signals between tobacco and sunflower from one side and the Orobanche spp. from the other side.
