Abstract
THE retarding action of neutron rays upon the roots of wheat seedlings has been reported by R. E. Zirkle, P. C. Aebersold and E. R. Dempster1, and recently by R. E. Zirkle and I. Lampe2, but the daily growth of individual seedlings after irradiation has not been reported yet. In the present experiments, the lengths of individual roots of Vicia Faba, which were exposed to radiations produced by bombarding a beryllium target with 2.8 Mev. deuterons from the cyclotron of this laboratory, were measured day by day after the exposure.
