The effect is most pronounced in young leaves; it is, however, transient. After six days in old leaves and after 12 days in young leaves, the caffeine content has decreased to its normal leve. The results are discussed in relation to the recently discovered fact that cytokinins are constituents of rare nucleotides of seryl-t-RNA. It seems plausible that the methylations necessary in the synthesis of caffeine are linked with this primary function of cytokinins
