[Micromorphometric analysis of root cap cells in Allium cepa]

A two-dimensional micromorphometric analysis of a root cap in Allium cepa included the measurement of the areas of about six thousand cell profiles on both longitudinal and transversal sections. Basing on the results of this analysis, quantitative descriptions of two cell populations from the columella and periferic part of the root cap have been created. The scheme of arrangement of root cap cells, located at a distance of 250 microm or less from a root tip, has been developed.
