Vegetative shoots of Arizona cypress (Cupressus arizonica Greene) were found to contain an estimated 40 to 70 mug of gibberellin-like activity per kg. Based on elution patterns of silicic acid and celite partition columns, mobilities on thin layer chromatograms and specificity of the cucumber, d-3 dwarf maize, dwarf pea, and barley half seed bioassays it was possible to determine that the tissue contained at least 5 acidic, ethyl acetate-soluble gibberellin-like substances. The major one would appear to be GA(3). In addition, GA(9), GA(4), and/or GA(7)-like compounds, and 2 unidentified gibberellin-like substances are present.
