Geotropic and phototropic responses of seedlings of rape, wheat and rye‐grass are inhibited by 9‐fluorenol‐9‐carboxylic acid and certain of its substituted derivatives. The antitropic effect of these and other acidic aromatic substances is discussed, and it is suggested that they may act through a competitive interference with the lateral transport of β‐indolylacetic acid.
