Karyological investigation in the Poaceae from Tunisian steppes

Acta Botanica Gallica 141(3): 327-341

Karyological investigation in the Poaceae from Tunisian steppes

The chromosome numbers of twenty five Poaceae species in the add Tunisian flora have been determined. Sixteen of these taxa are polyploids: three hexaploids, twelve tetraploids and one triploid. Six new chromosomes numbers have been found : Aristida obtusa Del. (n = 22), Panicum turgidum Forsk. (n = 27), Pennisetum dichotomum Del. (n = 27), Pennisetum setaceum Desf. (n = 18), Oryzopsis miliacea L. (n = 18) and Stipa tenacissima L. (n = 33).
