Karyotype analysis in Chaerophyllum cicutaria Vill. with special emphasis on satellited chromosomes

Abstract

Karyological studies were carried out on plants of <em>Chaerophyllum cicutaria (Umbelliferae)</em>, which came from both lowland and montane natural populations. The chromosome number in all the examined plants was 2n = 22 and their karyotypes, though similar in general, showed some minute but distinct differences. There was` a single pair of SAT chromosomes in the chromosome complement. They had compound satellites divided into two or three segments. Seven morphological types of SAT chromosomes differing in number and size of satellite segments were distinguished. With respect to SAT chromosome morphology, the species showed both intra- and interpopulational karyological variation.
