Young coffee plants were allowed to absorb radiophosphate via leaves during 30, 60, 90 and 120 minutes and via roots during 24 hours. It was verified that leaf absorption was almost twice more intense than root uptake despite the considerable difference in time of contact which would favour the latter. Translocation of leaf applied material was also more marked.
