Ricinine-3,5-(14)C (N-methyl-3-cyano-4-methoxy-2-pyridone) administered to senescent leaves of Ricinus communis L. was translocated to all other tissues of the plant. Developing fruit and especially seeds were found to be labeled the most rapidly. Young growing leaves and other developing tissues of
