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.
