S ummary Bloom node leaves and pods of 25‐35‐day‐old fruits of Vicia faba L. var. Triple White, were allowed to photosynthesize in 14 CO 2 and the distribution of label in pod and seed amino acids determined by autoradiography. The pod was shown to export carbon to the seeds chiefly as aspartic acid. The leaf contributed sugars and serine directly and many other amino acids after metabolism of precursor compounds in the pod. The seed was apparently capable of amino acid interconversion and synthesis. Both leaf and pod donated carbon to seed protein, the leaf providing about ten times as much total seed carbon as did the pod.
