摘要：

The growth and the content of endogenous cytokinins (CKs) of current-year-old shoots from juniper plants ( Juniperus communis L.) growing over and off ore site were compared. The juniper shoots from ore site ( M plants) had higher metal content and exhibited delayed growth. Less bases and nucleosides of Z- and iP- type CK and more iP- conjugates were present in the M shoots. These changes were probably due to inhibited CK export from the roots and/or altered CK metabolism forming less biologically active CKs.
