Abstract
Algit Super®, an extract ofAscophyllum nodosum, was found to be an effective stimulant for the germination ofOrobanche ramosa seeds. The biological activity of Algit Super® was tested at a wide range of concentrations from 2.5 v/v to 1.2 × 10−3 v/v. The seed germination in all studiedO. ramosa populations showed a concentration dependence, with an inhibitory effect at higher concentrations. The response ofO. ramosa to Algit Super® resembled its response to the reference stimulant GR24. VariousO. ramosa populations demonstrated differential response to the stimulant.
