The activity of IAA‐oxidising enzymes from Lens roots is enhanced in vitro by dalapon (2,2‐dichloropropionic acid) and perfluidone (1,1,1 ‐trifluoro‐ N ‐[2‐methyl‐4‐(phenylsulphonyl)phenyl]methanesulphonamide). When concentrations are greater than 10 −8 M, both these herbicides act as activators. In vivo higher levels of the enzymatic activity are obtained when seed germination is carried out in the presence of 10 −5 M perfluidone or 10 −3 M dalapon. Gas‐liquid chromatography is used for IAA determination.
