SUMMARY 14 CO 2 was fed to the bloom node leaf subtending 30‐35‐day‐old broad bean pods, and the leaf, pod and seeds harvested during 19 hours. An immediate transfer of label from leaf to fruit was observed. During the night, a second peak of activity occurred in the fruit owing to an influx of labelled carbohydrate into the seed, but this was not at the expense of leaf carbon. Possible sources of this carbohydrate are discussed.
