The flowering response by plants of Lolium temulentum after exposure to 1 long day was significantly reduced by single applications of abscisin 11 to the leaves or near the shoot apex. The time course of this inhibitory effect suggests that abscisin 11 acts at the shoot apex when the floral stimulus arrives there.
