Abstract

The uptake, translocation, and fate of 14C-labeled 3,6-dichloro-o-anisic acid (14C-dicamba) were studied in wheat (Triticum aestivum L., 'Selkirk’) and wild buckwheat (Polygonum convolvulus L.) as resistant and susceptible species, respectively. Selectivity could not be explained by interspecific differences in uptake of 14C-dicamba by leaf sections submerged in exogenous solutions. 14C-dicamba accumulated in meristems of wild buckwheat but not in the youngest tillers of wheat. Moreover, wheat main culms conjugated or metabolized 14C-dicamba more quickly than did wild buckwheat meristems. Therefore, selectivity of dicamba apparently was related to interspecific differences in translocation and metabolism.
