A series of experiments were carried out in order to elucidate whether acetylsalicylic acid (ASA) fed via petioles to beans could affect transpiration rate. In comparison with the water control it was found that a 10 −3 M ASA reduces transpiration as much as 43%, a reduction equivalent to 5 × 10 −5 M abscisic acid (ABA). Preliminary kinetics on the ABA, ASA and the water control on transpiration rate are presented and the results discussed.
