The endogenous cytokinins in cones of the hop plant (Humulus lupulus L. cv. Shinshuwase) were identified by combined gas chromatography and selected ion current monitoring (GC-SIM) and high performance liquid chromatography as ribosyl-cis-zeatin, ribosyl-trans-zeatin, cis-zeatin, trans-zeatin and ribosyl-trans-zeatin-O-glucoside. The contents of these cytokinins in both fertilized and unfertilized cones at various growth stages were determined using GC-SIM and/or bioassay. Based on these data, the rapid growth of the fertilized cone is attributed mainly to ribosyl-trans-zeatin which accumulates mostly in the seed. Ribosyl-cis-zeatin was found in both fertilized and unfertilized cones. In the latter, ribosyl-cis-zeatin was quantitatively a major cytokinin and seemed to cooperate with ribosyl-trans-zeatin and trans-zeatin in promoting the growth.
