Cytotaxonomic Studies of Three Ornamental Aroids

Full Text PDF


Cytotaxanomical analysis carried out on three ornamental aroids (Anchomanes difformis, Anchomanes hookeri and Arum maculatum) proved that cytological studies is none negligible tool in phylogeny and scientific classificationns of plants. Aceto-orcein stain squash technique was used in this study. Anchomanes difformis and Anchomanes. hookeri showed more relatedness in chromosome number and chromosome morphology, sharing the same chromosome number 2n=13, while Arum maculatum has 2n=8. The following karyotypes formular were revealed: 2n=8=3M+3SM+2ST in Arum maculatum; 2n=13=5M+1SM+7ST in A. difformis; and 2n=13=3M+6SM+4 A. hookeri. Other karyotype parameters investigated like CI%, AsI and degree of asymmetry of the genomes supported current taxonomic ranking
