Karyological notes on seven Trifolium L. taxa from Turkey.

Three basic chromosome counts (x:5, 7 and 8) were determined in this study. It was found that T. resupinatum L. var. resupinatum, T. stellatum L. var. stellatum and T. purpureum Lois. var. purpureum have 2n: 16; T. arvense var. arvense, T. hausknechtii Boiss. var. hausknechtii and T. pauciflorum d'Urv. have 2n.14; T. hirtum has 2n:10 chromosome numbers according to the present results. All chromosomes have median point (M), median region (m) centromeres and satellites were not observed in the studied Trifolium taxa. The chromosome number and morphology of T. haussknechtii Boiss. var. haussknechtii and T. pauciflorum d'Urv. are reported for the first time. [ABSTRACT FROM AUTHOR]
