| Abstract: | ![]()
Phaseolus vulgaris plants decapitated above the primary leaves accumulate high cytokinin activity. The major cytokinin in these leaves was identified by Sephadex LH 20 chromatography, sensitivity to  -glucosidase and permanganate oxidation, and by combined gas chromatography-mass spectrometry as 6-(4-O--D-glucosyl-3-methylbutylamino) purine, (dihydrozeatin-O--D-glucoside). A possible reason for the persistance of this compound in the primary leaves is discussed.Abbreviations BSA Bis-(trimethylsilyl)-acetamide - DHZ dihydrozeatin - DHZOG dihydrozeatin-O--D-glucoside - TMS trimethylsilyl - Z zeatin |
