1991

The karyotypes of some populations of the species Iris pallida Lam., I. illyrica Tomm. and I. pseudopallida Trinajstic (series Pallidae) were investigated. A studies of somatic chromosome morphology was made using root-tip squash technique and aceto-carmine stain, after pretreatment with p-dichlorbenzene. For all populations investigated mitotic number of chromosomes 2n = 24 has been established, which corresponds to previous studies of species from the series Pallidae (Simonet 1934, Mitra 1956, Lausi 1964, Mitic 1989). Morphometrical analysis has shown variations of karyotypes, which in I. illyrica species go down to population level. The differences among karyotypic appearances of the species under study were established, especially regarding the position of chromosomes with satellites within karyotypes. Also, the similarity of karyotypes in populations studied now with karyotypes of previously investigated populations (Mitra 1956, Lausi 1964) has been established.
