Summary. After the 4‐ or 5‐leaf stage in young barley plants, there is a decrease in the translocation of 2,4‐D from the leaves to the root system. It is shown that there is no relation between this phenomenon and ear initiation, which occurs at this stage of development. Movement of 2,4‐D out of leaves of the tiller in the axils of the 1st and 2nd leaves was also shown to be very small. There is some evidence for a‘block’in the movement of 2,4‐D in established grass plants. La migration du 2,4‐D marqué dans l'orge
