Oxindole-3-acetic acid (OxIAA) has been identified in germinating seeds of Scots pine (Pinus sylvestris) using gas chromatography-mass spectrometry. Seeds germinated for 5 d contained 2.7 ng OxIAA·g-1 (dry weight) whereas ungerminated seeds contained 0.2 ng·g-1. Isotopically labelled OxIAA was formed in seeds incubated with [1′-14C]-, [2′-14C]- or [2H5]indole-3-acetic acid.
