Striga emergence in response to the application of various SL analogs in pots under greenhouse conditions. (A) Representative pots of greenhouse study, showing Striga emergence under different treatments. (B) Number of Striga plants that emerged in mock, MP3, MP16, or Nijmegen-1 treatment. The selected SL analogs were applied twice at a 1 μM concentration to 10-day preconditioned Striga-infested pots. (C) Rice plant height in response to different treatments. Data are means ± SE (n = 6). Error bars represent the standard error of the mean. Values in parenthesis show the percentage increase (+) or decrease (−) over mock treatment. For each SL analog, treatments with various asterisks differ significantly according to one-way analysis of variance (ANOVA), ** p < 0.005, *** p < 0.005, **** p < 0.0005).
