Abstract :The nuclear DNA contents and nuclear areas of some endemic Hedysarum L. species were investigated. A significant variation in the DNA content of Hedysarum species was established. The 2C nuclear DNA amount in the Hedysarum species (x = 8) ranged from approximately 4 to 6 picograms. It was found that the variation in the 2C nuclear DNA content was not related to chromosome numbers. However, there was a very high positive linear relationship between nuclear DNA content and nuclear area.
