Number of nucleoli in diploids and polyploids of the genus Achillea L.
Acta Societatis Botanicorum Poloniae, 2014 Nucleoli were counted in 9228 interphase nuclei of the apical root meristem of 40 Achillea L. taxa (di-, tetra-. hexa- and octoploids). It was established that the distribution of nucleoli number in an interphase nucleus can be used as a rough practical ...
