Abstract
A study of Cenchrus ciliaris was conducted in a Tunisian arid zone of between 1996 and 2002. Karyological analysis of twenty populations and reproduction observations on this species by seed were made. The chromosomes numbers at diakinesis I show a high degree of aneuploidy and vary between n = 18 and 36. The hexaploid populations (n = 27) are most frequent. The distribution of both populations, based on chromosome numbers, doesn't answer to the very determined ecological requirements. The number of spike production and the fertility rate were determined for plant in pastorutum. Seed production is generally very high. The seeds are able to germinate under laboratory conditions, and the plant can reproduce in this manner in the field.
