Identification of IAA in phloem and root pressure saps of Ricinus communis L. by mass spectrometry.
Using gas-liquid chromatography and mass spectrometry, IAA was identified in the phloem sap and root pressure sap of Ricinus communis L. The bark incision procedure for collecting phloem sap was not associated with a significant rise in the IAA level in the bark tissues.
