Effect of Triton X-100, KK023-N1, KK023-N2, and KK094 on S. hermonthica seed germination. Preconditioned Striga seeds (∼50–100 per disc) were first pretreated with the indicated concentrations of inhibitors for 24 h, and then mixture of each inhibitor at the indicated concentrations along with GR24 at (A) 0.5 nM and (B) 1 nM was applied for another 24 h. Germinated and nongerminated seeds were counted from each disc to calculate percentage germination. Data are means ± se (n = 6 discs). The negative value on top of each bar is the percentage reduction of Striga seed germination over control.
