Abstract
A QUIESCENT centre in root meristems was first reported by Clowes1, who fed radioactive nucleic acid precursors and radioactive amino-acids to root tips. From autoradiographs of median longitudinal sections he demonstrated the presence of a patch of cells in the meristem which did not incorporate so much radioactivity as cells in other regions of the meristem1–3. During the course of experiments with excised tomato roots, grown in a White's medium as modified by Boll and Street4, it was necessary to prepare autoradiographs of longitudinal sections of roots which had been in contact with sucrose-U-14C or glucose-U-14C.
