• Fronds of marine algae, especially green alga, Codium latum, and red alga, Porphyra tenera, evolved a quantity of ethylene when IAA was exogenously applied, while brown alga, Padina arborescens, evolved only a little. Propionic acid, when added together with IAA, noticeably enhanced IAA-induced ethylene evolution in P. tenera and P. arborescens. This evolution was also enhanced by added acrylic acid in P. arborescens but not in P. tenera. It was promoted by methionine, though only at a high concentration (0.1 M), in P. tenera but not in P. arborescens. The rate of ethylene evolution was highest at 12℃ among the incubation temperatures tested of 5, 12 and 15℃. The conversion of ^<14>C-3-methionine to radioactive ethylene in P. tenera was remarkably inhibited by a proteinaceous inhibitor from P. tenera.
