Ulva fasciata (Ulvales, Chlorophyta) and Dictyota humifusa (Dictyotales, Phaeophyta) were collected bimonthly from the inter-tidal zone at Rocky Bay, South Africa. cis-Zeatin, isopentenyladenine and their ribotide and riboside conjugates were the main cytokinins present in both seaweeds with low concentrations of trans-zeatin, dihydrozeatin and aromatic cytokinins. Based on the cytokinins detected, we propose that the ribotides are also the first intermediates formed during de novo biosynthesis in seaweeds and are subsequently converted to free-bases and ribosides. The only indole compounds detected in both species were free indole-3-acetic acid and indole-3-acetamide (IAM). Endogenous abscisic acid was detected in most samples with levels in U. fasciata generally being higher than those measured in D. humifusa.
