Cytological study of Allium cepa and Allium sativum

ActaSatech 9 (1):113-120 (2017)

Abstract

The large number of species in the Allium genus has necessitated comparative analysis of related species which has always been used in many cases to describe patterns and directions of chromosomal evolution within a group. This study was carried out to cytologically analyse two species of Allium- Allium cepa and Allium sativum. All the four stages of cell division were observed in both species, although well spread metaphase chromosomes could not be observed in A. sativum which limited the extent to which we could cytologically evaluate the species. Allium cepa in this study show cell with a complement of sixteen chromosomes. A total chromosome length of 577.5 µm was observed in the best c-metaphase spread with the longest chromosome being 43.4µm and the shortest 27.9 µm. Further studies are still required in the karyotype analysis of A. sativum from Nigeria
