| Abstract | ||
| Diploid and haploid chromosome number were counted for eight species of Polygonaceae including aquatic and terrestrial plant Calligonum comosum(L.) Her , Emex spinosus (L.) Campd. , Polygonum aviculare L. , P. argyrocoleon Steud. ex. Kunze , Persicaria lapathifolia (L.) S.F. Gray , P.salcifolia (Brouss. Ex.Willd) Assenov , Rumex dentatus L.and R. vesicarius L. The results appears that chromosome numbers of aquatic species (P. lapathifolia and P. salcifolia) differs from other terrestrial species. Haploid numbers were counted from pollen mother cells , and also diploid numbers were counted from root tips. These numbers are 2n=18,20 &22, n=9 , 10, 11 &20 .Karyotype variations of these species were analyzed. | ||
