Abstract

This paper elucidates the effects of chloroflurenol (morphactin, IT 3456) treatment on the kinetics of 14C-IAA transport through Zea mays L. (cv. Orla-266) coleoptile segments. Maximum inhibition of transport was achieved when chloroflurenol remained in contact with the tissue segments for at least 20 min or more. The treatment, without materially affecting the 14C-IAA-transport polarity, or uptake, significantly reduced the velocity from 20.5 mm h−1 to 8.79 mm h−1 and also the intensity from 919 (ct/min) h−1 to 413 (ct/min) h−1.
