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 OxIAAยทg(-1) (dry weight) whereas ungerminated seeds contained 0.2 ngยทg(-1). Isotopically labelled OxIAA was f

## Abstract A general method for microscale synthesis of ^14^Cโlabeled indoleโ3โacetic acids with halogen substitutions in the benzene ring is described. The method utilizes halogen substituted phenylhydrazines reacted with [^14^C]โ2โoxoglutarate to generate the halogenated indoleโ3โacetic acid. 3โ
## Abstract The synthesis of 3โindolylacetic acid labelled with ^14^C in side chain carbon atoms has been effected using (1โ^14^C)glycolic acid, (1,2โ^14^C~2~)glycolic acid and (2โ^14^C)glycolic acid in an yield of 40โ60%. Some of the parameters that affect the synthesis have been studied and the r
