Abstract
Summary Uptake and metabolism of the synthetic auxin α -chloro- β -(3-chloro-o-tolyl)propionitrile (Cl-ClTPN) were studied in intact Mung bean seedlings and in hypocotyl segments. Cl-ClTPN was taken up much faster by hypocotyl segments than by roots of intact plants. In extracts of plants treated with Cl-ClTPN several metabolites were detected: α -chloro- β -(3-chloro-o-tolyl)propionic acid, α -hydroxy- β -(3-chloro-o-tolyl)propionitrile and α -(3-chloro-o-tolyl)acetic acid (ClTAA). Besides, a lot of unidentified metabolites, most of them being apolar, could be revealed. From the identified metabolites and from the growth promoting activity of several homologues of them in the Avena cylinder test, it is suggested that Cl-ClTPN is converted to ClTAA, which is supposed to be the physiological active form of Cl-ClTPN.
