Petioles and apical regions of Phaseolus vulgaris var. Black Valentine were subjected to ionizing radiation to study the effect on the translocation process. Petiole irradiation produced no discernible effect. Inhibition of translocation to the irradiated meristems was reversed by application of the auxin naphthaleneacetic acid.
