SUMMARY The dose‐response curves for the effect of red and green light on the synthesis of anthocyanin in mustard seedlings show a plateau. This plateau is reached with energy doses of 1 (red light) resp. 10 (green light) μW sec cm −2 . A further increase in the amount of anthocyanin is induced by red or green light doses exceeding 10 3 μW sec cm −2 . Thus the occurrence of a plateau in the dose‐response curve of a phytochrome‐mediated process is not restricted to the growth of the Avena mesocotyl and coleoptile.
