Germination-inducing activity on Phelipanche aegyptiaca seeds of rac-1–9 and of strigol, ST23b, EGO10, and EDOT at different concentrations, compared to rac-GR24 0.1 μM as a positive control and to acetone as a negative control. The y-axis shows the percentage of germinated seeds normalized to rac-GR24 at 0.1 μM, which was set to 100%. The x-axis indicates the range of concentrations. Data are means (±SD) of n>250 seeds. Confidence intervals at 95% are used to express errors of the means. The data for for rac-1–9 are indicated by ‘D-lactams’.
