The metabolism of /sup 14/C-zeatin was examined in embryos of P. coccineus cvs. Scarlet Runner (SR) and Desiree (Des). The O-xylosyl derivatives of zeatin and ribosylzeatin previously isolated from P. vulgaris embryos were found in both cultivars. In addition, two new metabolites were isolated from SR embryos and were identified by enzymatic degradation and GC-MS analyses as O-xylosyldihydrozeatin and its ribonucleaside. O-xylosylation of zeatin was also detected in P. acutifolius, but not in P. lunatus embryos. Both the formation of O-xylosyl derivatives and side chain reduction seem to be genotype specific. Moreover, they are most pronounced at early stages of embryo development.
