Abstract:
:The cytokinins present in the spring sap of Acer pseudoplatanus L. were investigated. Ribosyl-trans-zeatin, trans-zeatin and dihydrozeatin were isolated and identified by combined gas chromatography-mass spectrometry (GC-MS). A number of other cytokinin active fractions were observed. One of these was less polar than zeatin and did not behave as any known cytokinin. Two other fractions were more polar than ribosylzeatin and were unstable. A decomposition product of one of these was identified as ribosyl-trans-zeatin by GC-MS. The possible nature of the unstable compounds is discussed. Data on the changes in cytokinin activity of the various fractions during spring 1973 are presented and discussed.
