The principal biologically active cytokinins in xylem exudate of young Phaseolus vulgaris L. plants were identified by bioassay, high-performance liquid chromatography, enzymic degradation and combined gas chromatography-mass spectrometry (selected ion monitoring) a zeatin riboside, zeatin nucleotide, dihydrozeatin riboside, dihydrozeatin nucleotide, O-glucosyl zeatin, O-glycosyl dihydrozeatin, O-glucosyl dihydrozeatin riboside, and O-glucosyl dihydrozeatin nucleotide. Trace amounts of O-glucosyl zeatin riboside and O-glucosyl zeatin nucleotide were also detected.
