Transport and regulative properties of phenylacetic acid

Original Papers


The mode of transport and regulative properties of phenylacetic acid (PAA) were studied in 11-cm long segments of pea epicotyls capable of growth. The transport of PAA m both the basipetal and aeropetal direction was limited to tissues situated immediately below and/or above the site of its application. PAA was able to promote the flow of14C-ABA in the acropetal direction. PAA-initiated thickening growth was probably the cause of this promotion.
