Abstrakt: Changes in the levels of endogenous cytokinins during Norway spruce somatic embryogenesis were described. New LC-MS method was used, enabling the detection of almost 20 cytokinins. Selected cytokinins were also analyzed using immunodetection in situ. We suppose somatic embryogenesis is co-regulated both by marked changes of endogenous cytokinins during particular stages of the process, and by the changes of other endogenous phytohormones, IAA and ABA.
