Using combined gas chromatography and mass spectrometry a growth‐promoting, organic component of sea water has been quantitatively estimated and identified as the cytokinin 6‐(3 methyl‐2‐butenylamino) purine. Additions of this cytokinin, kinetin or sea water from the Fucus‐Ascophyllum zone increased the growth of Ectocarpus confervoides and Pylaiella litoralis in artificial sea water. Additions of kinetin to bacteria‐free cultures of Ectocarpus fasciculatus also initiated the production of upright ectocarpoid filaments.
