Abstract

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'-(14)C]-, [2'-(14)C]- or [(2)H5]indole-3-acetic acid.
