Fresh pollen of Ornithogalum caudatum was germinated in the absence or presence of trans‐cinnamic acid (t‐CA), trans‐cinnamaldehyde (t‐CAld) and related compounds, and germination percentage studied. Hydrocinnamic acid, t‐CA, and t‐CAld reduced germination to 50% of the control at 20–40 mg/liter. Hydrocinnamaldehyde, 3‐phenyl‐1‐propanol and phenylacetic acid gave 50% reduction at 70–80 mg/liter, and caffeic acid, ferulic acid, phenethyl alcohol, coumarin, styrene, phenylalanine or ethyl cinnamate required 200 mg/liter or more for similar reduction in germination percentage. The inhibition of germination by t‐CA could not be overcome by indole acetic acid and vice versa, indicating a lack of antiauxin activity.
