Abstract
Previous indirect evidence that the endogenous concentration of plant hormones of the auxin type is controlled by a limitation of transport over the physiological range of concentration was confirmed by measuring directly the transport of the native auxin, indoleacetic acid, through segments of Coleus stems.
