Publisher: 1972Subject(s): COFFEA ARABICA | FISIOLOGIA | CAFEINA | TRANSLOCACION | CAFEINA EN LOS GRANOS | COFFEA ARABICA | CAFFEINE | COFFEA ARABICA | CAFEINE In: Planta (Alemania, R.F.) v. 108(1) p. 11-20Summary: Caffeine transport in small amounts from leaf to leaf was demonstrated by application of doubly-lavelled caffeine. There was no translocation from the subtending leaves into the fruits, but heavy translocation from the pericarp into the seed tissue could be shown. The results were confirmed by the analysis of grafts between caffeine-containing and caffeine-free species. The importance of the pericarp with respect to the caffeine content of the mature coffee bean is discussed
