Abstract
The differing sensitivities of different forms of C. repens to picloram are attributed, in part, to the anatomical characteristics of the vegetative organs. Very susceptible plants showed well developed vascular systems in the stems and leaves, an increased number of stomata on the leaves and a thin cuticular layer, all of which promoted picloram assimilation and activity against the root system.
