Karyomorphological studies of Aponogeton appendiculatus Bruggen and Aponogeton crispus Thunb.

Abstract

The study focused on the correct taxonomic
identification and the determination of somatic chromosome
numbers of Aponogeton appendiculatus Bruggen and
Aponogeton crispus Thunb. A somatic chromosome number of
2n = 30 and 2n = 32 was observed in A. appendiculatus and
A. crispus, respectively. The chromosomes of both species
were short with median to submedian primary constriction.
The karyotypes were reasonably symmetrical, indicating the
primitiveness of the family in general.
