Rezumat:

For the first time the strigolactone composition in root exudates of host plants of rare Orobanche spp. occurring in the spontaneous flora have been investigated by LC-MS/MS analysis. The obtained results were discussed in the context with host specificity of Orobanche spp. The results show host plant specific qualitative differences in the composition of strigolactones. Known structures have been found, but there are also indications for related compounds, whose structures are not yet revealed. Evidence is seen for the assumption that the composition of strigolactone “bouquets” may determine the host specificity.
