SUMMARY Kinetin, zeatin or zeatin riboside applied to parts of excised leaves of Sagittaria graminea change the distance profile of 14 C‐α‐amino‐iso‐butyric acid translocation in these leaves. They probably enhance the rate of accumulation of the basipetally translocated amino acid. The metabolic inhibitor carbonyl cyanide m‐chlorophenylhydrazone (CCCP) appeared to act in a very similar way on amino acid translocation; it also caused chlorophyll retention. Some possible cytokinin‐CCCP relations are briefly discussed.
