Studies on the transport of caffeine in the arabica coffee plant


, : Studies on the transport of caffeine in the arabica coffee plant. Planta 108(1): 11-20

Caffein transport in small amounts from leaf to leaf was demonstrated by the application of doubly-labelled caffeine (3H and 14C). There was no translocation from the subtending leaves into the fruits, but heavy translocation from the pericarp into the seed tissue could be demonstrated. The results were confirmed by the analysis of grafts between caffeine-containing and caffeine-free Coffea species.
