title: Mass spectrometric measurement of zeatin glycoside levels in Vinca rosea L. crown gall tissue.
abstract: The range of zeatin glycosides found in crown gall tissue of Vinca rosea L. has been quantified using a mass spectrometric isotope dilution procedure. Problems in the quantitative analysis of cytokinins in plant extracts are discussed.
