Abstract:
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 indicator to distinguish between diploids and polyploids. The highest number of nucleoli (12) was found in an octoploid Achillea pannonica, but only in a small percentage of the nuclei (0.3% out of 283 nuclei).
